I. Sources for the collections of data I.1 Create a plan for the
collection of primary and secondary data for UAI study
Plan The first thing we need to prepare for the survey is
creating a plan. When we have a plan, we can divide and arrange
time logically to achive the best goals for the survey. The table
below is a plan of my team, Thanh Khe team.

Table 1: Survey planPopulation
Applying my team to create a plan to collect the primary and
secondary data for UAI study, the first thing my team need to do is
define the cluster of the information we collect. The cluster we
defined is the parents who have the high income and have the
children who will study in university in next or three years. We
will collect the data at Thanh Khe district, so we need to zone the
streets that belongs to Thanh Khe districts such as Dien Bien Phu,
Ham Nghi, Nguyen Tri Phuong, Tran Cao Van, Hai Phong, Le Duan, Phan
Thanh, Le Dinh Ly, etc.Sampling method We use the cluster method on
sampling method to divide and define the sample that we need to
give the survey and have the interviews. With cluster method, we
practice step by step as follow:Step 1: We apply the cluster to
divide belongs to the district and defind the people that are
suitable with the conditions that we want to get surveyStep 2: We
collect the address and bread winer names that belongs to Thanh Khe
district and is suitable with the defined conditionsStep 3:
Finally, we aplly to the random samplingSampling sizeWe calculate
the sampling size to know the total number of parents we need to
give the survey. The samling size is calculated by the formula
ME =
With Z = 90% = 1.645ME = 5% = 0.05P = 50% = 0.5
According to the formula and the data, we can calculate the
sampling size n= 260. This means that we will collect information
from 260 people that live at Thanh Khe district. It helps us reduce
expenses and time by allowing us to estimate information about a
whole population without having to survey each member of the
population. (Steven Julious; 2009)Source of data
Primary datais information that you collect directly from
first-hand experience. It is specifically for the purpose of your
research project. An advantage of primary data is that it is
specifically tailored to your research needs. Researchers can
collects the data by themselves, using surveys, interview or direct
observation (Shawn Grimsley, Marketing research). For example, in
recent research, the researcher needs to find out the level of
salary that the workers want to achieve after two years they work
for company. The researcher can give the survey or direct interview
with them. The workers answers are consider as primary data. (At
Work, Issue 54, Fall 2008: Institute for Work & Health,
Toronto)
Figure 1: Primary dataSource: Ghauri et al., 1995
Primary data is include direct interview (face to face) and
phone interview. With my team, we choose the direct interview (face
to face) by giving the survey at bread-winner house. We come to
houses that are suitable with our defined condition which are
located around the areas that we are living to collect the
information. By direct interview, we have change to contact with
the parents and give more information about the international
universities that they want to know. Moreover, we can explain
carefully for the respondents more information or somethings they
are interested.
Secondary data is the information that is collected in the past
or from other parties. It is for a purpose other than your current
research project but it has the relevance and utility for the
research.
Figure 2: Secondary dataSoure: Mahatra, Marketing Research
(p.108)Secondary data is divided into two parts: external and
internal data. The researhers can collect information from
published material such as internet or library. In addition to
this, secondary data tends to be readily available inexpensive to
obtain. We can examined the data for a longer period of time. For
example, we can look at a companys lost-time rates over several
years to see at trends. (At Work, Issue 54, Fall 2008: Institute
for Work & Health, Toronto)we can collect the secondary data at
Committee of People in precinct that belongs to Thanh Khe district
such as Thac Gian, Tan Chinh, Hoa Khe and etc. We come to there to
collect some necessary information such as the telephone numbers of
parents have children who will be in university in 3 next years and
have high income. Moreover, the committee of people in precinct can
provide us the list of people have high income at that ward. From
there, we can come and see the bread-winner house to give the
survey. The information from the committee of people in each ward
is really useful for us to find and list the parents that are
suitable with our given conditions. It helps us save much time to
find and make right decisions.I.2 Survey methodology and sampling
frame At the final step of the sampling process, a particular
survey sampling methodology is chosen and applied. The methodology
that is chosen depends on the types of survey. The survey sampling
methodology is divided into two main parts. That are probability
and non probability. (surveyonics,2011)
Figure 3: Survey sampling methodologySource: Principles of
Online Survey Design & Delivery, 2011Non probability
samplesAbout the non probability sampling method, it includes the
judgment and convenience sample. In non probability, samples are
selected from the population in some non random manner. Judgment
sampling is a common nonprobability method. The researchers select
the sample based on the judgment. This means that they choose the
samples base on their specific knowledge or expertise (Survey
sampling method, 2014). For example, when we want to research about
the level of income of people who are living in Danang city, we can
choose one or two districts in Danang city to research instead of
all the population in Danang city. However, when we use this
method, we need to make sure that the sample that is chosen is
truly representative of the entire population in Danang city.
Convenience sampling is used when there are a few available
members of the target population. At the name implies, the sample
is selected because of its convenience. It can help the researchers
save much time and cost. The researchers can choose sample from
whole population by random selecting. For example, at a shopping
mall, the manager wants to research about the level of satisfaction
of customers when they come to the shopping mall. He can choose
random the first 100 customers come to the shopping mall on the
morning to give survey. This method can be used for preliminary
research efforts to get a gross estimate of the results, without
waste much money or time (Survey sampling method, 2014).
Figure 4: convenience samplingSource: Visual learner, 2009
Probability samplesProbability sampling method is any method
that utilizes some form of random selection. The probability
samples are included simple random, systematic sampling, stratified
sampling and cluster sampling. The main benefit of this method is
that the researcher can guarantee the sample chosen is
representative of the population. This means that the conclusion is
efficiency and the researcher can give the right decision from the
results of the surveys. (Probability sampling, 2006)
Simple random sample is a sample selected in such a way that
every item in the population has an equal chance of being included
(business decision making book, 2010.p24)
Figure 5: Simple random sampling Source: Simple random
sampling
Systematic sample is often used instead of random sampling. It
works by selecting every nth item after a random start. After the
require sample size has been calculated, every nth record is chosen
from a list of population member. Systematic sampling is frequently
used to select a specified number of records from a computer file
(Survey sampling method, 2014).
Figure 6: Systematic samplingSource: SamplingTechniques,
2009
Stratified sampling is the best method of choosing a sample in
many situations because it reduces sampling error. The population
must be divided into strata or categories. The examples of this
method are male and female, employment and unemployment. With the
stratified method, the population is divided into groups that based
on the characteristics of each group. With each group, the
researcher chooses the random sample until they are enough for
researchers to do survey (Survey sampling method, 2014).
Figure 7: Stratified sampling Source: Probability sampling,
2006Cluster sampling is that representative sample from the
population is selected by using a probability, often simple random
sampling. Every member of population is assigned to only one group.
It makes sure that only individual within sampled cluster are
surveyed (Survey sampling method, 2014).
Figure 8: Cluster SamplingSource: Visual learner, 2009
Danang city has 7 districts, include Thanh Khe, Hai Chau, Son
Tra, Ngu Hanh Son, Hoa Vang, Lien Chieu and Cam Le district. Each
district is seen as a cluster. Our team is responsibility to
research Thanh Khe district. To survey about the usage attitude and
image survey for CIE in Danang city, we use cluster sampling to
choose Thanh Khe district, that belongs to Danang city and we
research all families that are living in Thanh Khe district that
are suitable with defined conditions. At Thanh Khe district, my
team comes to bread winners who have children are last year high
school or will be in university in 3 next years. Sample frameSample
frame is a complete list of all members of the population that we
need to research. The sample frame includes the numerical identify
for each individual and information about characteristics of
individual. (business dicrtionary)
Figure 9: Example of sample frameSource: Sample frame, 2002After
collecting information from respondents, we list the sample frame
of all respondents. The respondents are person who are living at
Thanh Khe district such as on Dien Bien Phu st, Tran Cao Van st,
Phan Thanh st, Doan Nhu Hai st and so on. The sample frame of my
team is attached in appendix part.
I.3 A questionnaire for Thanh Khe districtSurvey method is
divided into two broad categories: questionnaire and interview.
Figure 10: Questionnaire sample
Questionnaires are usually paper and pencil instrument that the
respondent complete. Nowadays, questionnaire survey is one of the
most popular survey method for statiscals. They can be easy to
approach the respondents to provide information and explain
carefully what respondents need to know. Questionnaire includes
mail survey, self administated, group administrated and household
drop off . Internet is becoming popular on the world so many
businesses use website as one of method to give online survey for
their customers such as mail survey or online questionnaire survey
on the websites. This method can save much time and cost for the
businesses who want to get survey (Types of survey, 2012).
Interview is completed by the interviwers that based on what the
respondents answer the question. Interview includes the face to
face interview, phone interview or online interview. In the face to
face interview, the researchers will work directly with the
respondents. They can have chance to probe or ask follow up
questions. Moreover, they will be easier to get opinions from the
interviewees and make the impression to them.
Figure 11: Interview sampleMy team uses both questionnaire and
face to face interview to get the best result for the survey. We
design the questionnaire that has 26 questions and come to the
respondents houses to give the questionnaire and also ask them some
questions that are related to the survey to get more opinions and
make impression. Moreover, our teams questionnaire focus on
investigating the popularity of the international university to
parents at Thanh Khe district and what they desire to the
international university, especialy Sunderland university. The
sample of questionnaire of my team is below:

information for decisions making
Figure 12: data collection processSource: Data collection
services, 2014
At the final step of data collection process ,we have to get the
final data set to present it throughout the tables and charts in
order to the managers can understand clearly about the survey and
make right decisions.Q1. The family have children will study in
University in the next three years:

As can be seen from the pie chart, the number of families who
have their children will study in the university in the next three
years say yes is 83%. In contrast, the number of families says no
is 17%. Yes percentage is higher than No percentage about 5 times.
Our team chooses families who choose Yes to continue the interview.
Combine to the families with high income above 20 millions, we
choose the higher percentage to continue the survey.Q3, The
International Universities comes to your mind:

Throughout the table and the bar chart, in FM, we can see that
the highest number is Sunderland university with 41 parents. The
lowest bumber is Seatle Pacific university with only 2 parents. In
OM choice, Sunderland university is still stand at the first with 3
parents. This means that Sunderland university has good strategies
in marketing. It helps Sunderland university be more and more
popular with the parents. Therefore, when they consider the
university for their children, Sunderland university also come
their mind.

The lowest percentage is workshop. Social network is also a helpful
tool with 24% parents know about it. The reason is in social
network, it has lower parents use it. In the real life, parents
have relationship with friends relative and neighborhood.
Therefore, if they are satisfied with the program, they can promote
and introduce it to others.Table 4: Source of program

we can see that, the table and the bar chart show the rate of
university that parents have seen in the past three months. In FM
choice, the highest rate is Sunderland university with 61 rates and
the lowest rate is Carnegie Mellon university with 2 rates. This
means that Sunderland university is becoming more and more popular
with parents. Q7, the field of study

Table 6: THE FIELD OF STUDY
Figure 17: The field of study
According to the bar chart and the table, we can see that the
highest percentage of the field of study that most of parents want
to orientate their children learn for future is business management
(with 27%). Which is followed by finance management and marketing
with 17% and 13%. Related to last figures, the main majors of the
University of Sunderland program in the first three year are
Business management, finance management and marketing. It is one of
reasons why parents know most about Sunderland program. The lowest
percentage is commerce with only has 3%.
Q11, who prarents know study in the same university?
Figure 18: Who parents know studying in the universityIn the bar
chart, the main element who parents know studying in the university
is children of friend with 36%. The lowest percentage is the choice
of others. The percentage of neighborhood and relatives is almost
the same with 27% and 23%. Thoes mean that parents often consult
opinions from their friends who also have children study in the
same university and believe them rather than see the advertisement.
It is the strength of word of mouth. Sunderland university can base
on this thing to make the right decision for marketing strategies
for future.II.2 Central tendencyMeanMean is the most popular and
well known of central tendency. It is average of a range of values
or quantitives. It is calculated by dividing the total of all
values by the number of values. The formula of Mean is presented as
follow: (Sample mean formula,formulas.tutorvista.com)It is also
presented like that (Sample mean
formula,formulas.tutorvista.com)With x is total of valuesn is
number of values
Applying to our collecting data table, we can calculate the mean
of each question of all respondens as some tables and charts
below:Q18:Importance of University quality and characteristics
Figure 19: Importance of university qualities and
characteristics
Rate
International environment3.07
International teaching staffs and lectures2.95

Having opportunities to study abroad easily2.71
Studying international universities with the lowest cost2.98
Having much opportunities to study and practice at international
companies3.23
Table 7: importance of qualities and characteristics
According to the table and chart, we can see that the value of
mean of diploma is recognized around the world get the highest rate
with 3.53, compare to the level of importance of characteristics,
it reaches level extremely important. This means that parents are
interested so much in whether the diploma of international
university is recognized by other countries on the world or not. It
is one of the most important characteristics that parents make
decision that should or shouldnot give their children come to
international universities. Following by diploma that are having
opportunities to study and practice at international companies with
3.23 and international environment with 3.07. Those compare to the
level of importance is quite important that results rated by
respondents. However, the lowest is having opportunities to study
aboard. The reason can be that parents mostly find a national
university with have a international degree than study aboard.
Q19: Assessment on quality and characteristics of University of
Sunderland.
Figure 20: The assessment on university qualities and
characteristics of Sunderland university
The bar chart shows about the assessment that parents vote for
characteristics at Sunderland University. As we can see that the
characteristics that has the highest voted is international
environment with 4.18 percentage. It is necessary for any students
who want to experience the international environment with the
lowest cost and the international lecture from many countries
around the world. In addition to this, the diploma is recognized by
most of countries around the world with 4.17 percent. Students can
transfer the Top-up year to any university after 3 years studying
at Sunderland University in Vietnam.
MedianMedianis the middle score for a set of data that has been
arranged in order of magnitude. The median is less affected by
outliers and skewed data (Measures of Central Tendency, 2013). The
median is computed by placing the numbers that are given in value
order and find the middle number (Median defintion, 2013).We can
calculate the median step by step.Step 1: We have a list of number
as follow {13, 23, 11, 16, 15, 10, 26}Step 2: We put them in the
order: {10, 11, 13, 15, 16, 23, 26}Step 3: We define the middle
number is 15, so the median is 15 (Median defintion, 2013).With
another example of median is that if total numbers on the list is
even numbered, we can define the median by choosing two middle
number, take their total and divide it into 2. The result of this
is the median. Applying to our data calculating table, with
question 1 to question 14, we can have the median of them

Table 8: Median calculating resultsAccording to the table, we
can see two types of results. It includes round numbers and decimal
number. This means that if the list of number is even numbered, the
result of median is often decimal number.ModeThe mode is the most
frequence number in data set. On the histogram, the mode represents
the highest colum in the chart or histogram. Therefore, you can
understand that the mode is shown as being a popular option of
respondends. We can see clearly how can the mode represent as the
charts follow:
Cu 18: MODE of Importance of University quality and
characteristics
Importance of University quality and characteristics
Figure 21: Importance of university quality and
characteristics
The bar chart shows the mode of the importance of university
quality and characteristics at international universities. The
number is represented on the table is the most frequency of rates
that reponsdents voted for each characteristics of international
universities. As we can see that the highest bar chart is diploma
is recognized around the world with 4, extremely important. All
rest of characteristics is rates as the same result is 3, quite
important. Therefore, parents give much attention that the diploma
is recognized around the world despite of studying Vietnam than
studying abroad. The marketer can focus on this point in order to
have the right marketing strategies for future.
Q19, The assessment on quality and characteristics of Sunderland
university.The Mode of assessment on quality and characteristics of
Sunderland university.
Figure 22: Assessment of quality and characteristics on
Sunderland university.
According to the bar chart, we can see that most of
characteristics of Sunderland university is voted with the highest
grade with 4, generally high. There is only 1 characteristics is
voted with 3, neither highly nor poorly. Thoes means that
Sunderland university can meet most of expected of parents when
they give their children come to international university.
Inaddtion to that, parents also give their high assessment fot all
characteristics of Sunderland university. Therefore, Sunderland
uiversity needs to preservate and improve to make Sunderland
university become better and better.Standart deviation Standart
deviation is a measure of the dispersion of a set of data from its
mean. The more spread apart the data, the higher the deviation.
Standard deviation is calculated as the square root of variance.
Its symbol is. In finance, standard deviation is applied to the
annual rate of return of an investment to measure the investment's
volatility. Standard deviation is also known as historical
volatility and is used by investors as a gauge for the amount of
expected volatility (investopedia, standart deviation
definition).The standart deviation is calculated by the formula
below:
(Standart deviation,bbc.co.uk)
Where n is sample size x is meanFor example:With factor like the
international environment, we can calculate like thatMean =
3.07Variance = 0.8309Sample size n = 100(Detail attached on
CD)Standard deviation: = 0.8973According to the standard deviation,
we can apply to our data calculating table and calculating the
standard deviation as the table follow:

II.3 Quartiles, percentiles and the correlation
coefficientCorrelation coefficientCorrelation coefficient is a
statistical measure of the degree to which changes to the value of
one variable predict change to the value of another. In positive
correlated variables, the value of them is both increasing or
decreasing. On the concentrary, in the negative correlated
variables, the value of one is increasing while the value of the
other is decreasing (Correlation coefficient, 2014). The
correlation coeffiencient are expressed between -1 and 1. When the
correlation is +1, it is the positive correlation coefficient. A
change of value of one variable will predict a same change
direction of the other variable. The correlation is -1 is the
negative correlation. A change of value of a one variable will
predict a opposite change direction of the other variable. Lesser
degrees of correlation are expressed as non-zero decimals. The

According to the table 9 and 10, we can see that the result of
correlation coefficient is 0.764036. so, it is the positive
correlation. The result belongs between 0.76 and 1 so it is strong
positive correlation.
