RESEARCHMETHODOLOGY
Data collection
• Preparing a questionnaire of two different fast food chains using
different variables
• Where people had to rate it on the scale of 1 to 10
• Data was collected from the people who had visited both McDonald
and KFC .
• The sample size taken into consideration was 60
• The mean was calculated and was further considered for the rest of
calculations

MEAN
MEAN:
• The most popular and widely used measure of representing the entire data by one value is called as Arithmetic Mean.
• INTERPRETATION:
The mean rating of McDONALD is high.
VARIABLES McD KFC
RATINGS 7.60 6.57
Median• It is a measure of central tendency which appears in the middle of order sequence of
values i.e. half of the observation in the set of the data are lower and half are greater than it .Hence median is called as ‘Positional Average’ .It is calculated as
• N/2 - Locate the median Class = Median Position• Median = L+ [{(N/2 – P.C.F)/F}×i]
Where, L=Lower limit of the class interval of median class P.C.F=Preceding Cumulative Frequency F=Frequency of median class i =class interval• INTERPRETATION:
The Median of VALUE FOR MONEY of McDONALD is high.
VARIABLES McD KFC
VALUE FOR MONEY 8 7
Mode• Mode is defined as the value which occurs maximum number of time i.e. which
has maximum frequency .
• Results:
This shows the mode of ambience of is more.
VARIABLE McD KFC
AMBIENCE
Standard Deviation• It is a measure of how much spread or variability is present in the sample. If all the number in
the sample are very close to each other in such cases SD is zero (0) and if the numbers are well dispersed than SD tends to be large. It is calculated as:
•
Standard Deviation (б) = ∑( x-x ) n-1
• Results:
The Standard deviation of KFC is higher which means that the availability of outlets is less.

SKEWNESS
• Measures of asymmetry of data – Positive or right skewed: Longer right tail– Negative or left skewed: Longer left tail
Formula:-• 3(Mean-Mode)• Std deviation
VARIABLE McD KFC
AMBIENCE
KURTOSIS
• In statistics, kurtosis is any measure of the "peakedness" of the probability distribution of a real-valued random variable.
We can say that the majority of the rating of the people lie around the mean
VARIABLE McD KFC
AMBIENCE
COEFFICIENT OF VARIATION
• Coefficient of Variation: The standard deviation of data divided by it’s mean. It is usually expressed in percent.Coefficient of Variation= 100

VARIABLE McD KFC
Availability of Outlets 20.24% 26.24%
Karl- Pearson’s Coefficient Of Correlation
• Correlation is a statistical tool with the help of which the
relationship between two or more variables is studied.
• The measure of correlation is called as co-efficient of
correlation and denoted by ‘r’.
• Types of correlation :
1) Positive correlation
2) Negative correlation
Co-efficient of Correlation(r) = ∑ x y
∑x² . ∑y²
Interpretation:-They both show a negative correlation.
VARIABLE McD KFC
QUANTITY V/SVALUE FOR MONEY
0.37 0.51
Conclusion
• The conclusion so drawn from the data was that both the places rated good on different variables and some did not. So it could be concluded that depending on customers priority for a particular variable the person could visit the restaurant which was good for that particular variable.
