Introduction

Our survey is focused on a very common chronic disease called Trisomy 21, which is

commonly known as Down syndrome. Down syndrome is a genetic disorder caused by the

presence of all or part of a third copy of chromosome 21.

It is typically associated with physical growth delays, characteristic facial features, and mild

to moderate intellectual disability. Abnormal reproductive cells do not carry out the functions

of a reproductive cells and replicates an extra copy of chromosome 21. Those with Down

syndrome nearly always have physical and intellectual disabilities. As adults, their mental

abilities are typically similar to those of an 8- or 9-year-old. They also typically have poor

immune function and generally reach developmental milestones at a later age. They have an

increased risk of a number of other health problems, including congenital heart disease,

epilepsy, leukaemia, thyroid diseases, and mental disorders, among others.

However, in both men and women worldwide, not much people know about some hard facts

about it. In this survey, we had prepared some questions regarding Down syndrome, such as

the symptoms of Down syndrome, causes of

Down syndrome and the effects of Down syndrome. We also included some facts that are not

commonly known about lung cancer like the probability of cultural effects and life

expectancy of a Down syndrome patient. What we want to learn through this survey is the

comparison of knowledge of Taylor’s students between females and males. We will analyse

the ratio of the answers from our respondents to learn how much the students here

understands about Down syndrome.

Objectives

We have chosen to focus on Taylors students of female and male respondents for our survey

question. Our objectives of the survey are firstly, to test and compare the knowledge of both

student genders about Down syndrome as people often misunderstand the causes and

symptoms of Down syndrome. Secondly, we are to get an accurate result from different

people as we have a minimum of 300 personal individual targets. This way, we could create a

fair statistic to compare the results. Lastly, we are to complete everything and then come to a

conclusion of the survey.

METHODOLOGY

Since we were targeting 300 Taylors students for the survey, each of us were responsible to

survey 50 respondents each, of course those that finished earlier could help the others to

complete and pass the surveys around.

We used two ways to survey the respondents. One, we used the conventional survey forms

and distributed them when we see a potential respondent. The second, we also utilized

Google Docs to make digital a survey page so that we can send the forms efficiently via

social medias such as Facebook. Our respondents include family members, relatives, friends,

strangers, students and staffs in Taylors’ University. We later transferred the data received

into forms. We spent 2 weeks of surveying from 27th of December to 9th of January, and

then gathered the information together to do the statistics analysis.

After gathering all the completed survey forms, a total of 159 females and 141 males, each of

us analyse our own 50 forms, (me and David shared a 100 forms between us) and then

gathered all the information together to make our statistics analysis for this report. We first

discuss with each other about the calculations needed and the appropriate diagrams to portray

the information, and we transfer all the information into the report.

Students at Taylors University Lakeside Campus

Page 19: Final report statistics

Conclusion

In conclusion, we have acquired enough information to understand the students’ level of

understanding of Down Syndrome. From the statistics analysis, we could see that the female

class has only got 5 questions higher than the male class while the male class has 10

questions higher than female students. Besides, the male class has also answered a higher

percentage of correct answers compared to the female classes. Therefore it could be

concluded that male students has a higher understanding of Down syndrome compared to

Female students.
