Sample size for thesis

What should be sample size for phd thesis

Study related to consumer behavior, mumbai city

[ADITYA KUMAR SAHU]

Dear Madam,

If it is a empirical study, the sample size would depend on the number of variables/constructs/factors you are going to take in your analysis.

The rule of thumb suggests that 

sample size = (total number of statements/items in your study) * 5 

for obtaining a better sample adequacy.

Otherwise, for management Research, involving primary data, a large sample, usually 1000 or more is suggested by leading management departments of india.

There are various ways for determining the appropriate sample size.

It depends upon number of factors:

1. Population type ------- Infinite population or finite population

2. Type of scale --- 5 point Likert scale or 7 point likert scale

3 Alpha level (5%) for social sciences

4. Acceptable margin of error which is 5% for categorical data and 3% for continuous data;

   
Now there can be 4 possible cases that actually will decide the appropriate sample size

1. Infinite population (Continuous Data) ---- 5 point Likert scale or 7 point likert scale

For this case for 5 point Likert scale minimum sample size is 2964

2 Infinite population (Categorical Data)

For this case the minimum sample size is 384

3.Finite population (Continuous Data) ---- 5 point Likert scale or 7 point likert scale

For this case (say n= 10,000) for 5 point Likert scale minimum sample size is 2945

4.Finite population (Categorical Data)
For this case the minimum sample size is 370

Dear Nikisha

Mir has explained the concepts beautifully.

Determining the sample size is the 6th step in the process of sample design.

I've also explained the same on https://www.youtube.com/playlist?list=PLzUJUtTJcj8QUTu-fc3odVazY4-uoR7Is

Best wishes
