Here, for measuring sample size , I have used Cochran formula. I took around 600 plus as respondents.
My target population is supermarket customers in Bangladesh ( all over the country).
I have 8 Exogenous variables, 1 Intervening variable (Customer Satisfaction) and 1 Endogenous variable (Customer Loyalty).
Data and insights are also being collected from 60 personnels including supermarket experts, entrepreneurs and customers by in-depth interview.
Is my sample size alright?
Mohammad Kamrul Ahsan in general the number of respondents needs to be between 300 and over. For your side, 600 and over (600 - 800 respondents) may be convenient for the research. 365 respondents had been used in my research.
