Please help me here. I am doing a study on consumer reaction towards E-marketing - A case study in Guwahati City,Assam and am stuck with the sampling design.
The proposed environment of the study shall consist of all the employees of small- and medium-sized organizations in Guwahati city of Assam, who have access to the Internet and have made at least one online purchase in the last one year.
Sampling Unit shall comprise of 10, purposively selected wards, out of the total 60 number of wards in Guwahati city, covering 50 small and medium sized organizations in each ward.
Sample size: A total number of 500 respondents shall be surveyed for the purpose, with not more than 5 respondents, in case of each small sized organisation and 10 in case of each medium sized organisation, until the total target of 500 respondents have been arrived at. However, the major problem lies here.
1. How should I select the enterprise in each ward?
2 And after selecting the ward, how should I select the respondents (sample) of these enterprises? (Not getting a proper scientific sampling technique).
For the purpose of the study, the parameter of interest is that the respondents must be internet users and has to have made at least one online purchase in the past one year.
Dear Tapati
You can do a survey and publish it on your website. Then pass the information to the employees of Branches to asked to complete a survey. From the results of these surveys choose which fulfill your criteria.
I think you may need to do stratified random sampling.
you have to generate a list with all wards you have. [categorize them into small, medium, and large] then randomly select the desired number of wards which correspond to your sampling design.
Thank you very much for your answer Professor Muayyad Ahmad.
Sir, I have a list of the total number of wards. It is 60 in number. Am planning to use convenient sampling to arrive at 10 wards out of the total 60. Then, select 50 SMEs from the 10 wards.The problem that lies here is-
1. How do I go about in choosing the small and medium enterprises in each ward?
2. And after selecting the ward, what should be the sampling technique to select the ultimate respondent?
Initially you can go for purposive sampling but later as Professor Ahmad has suggested go for stratified random sampling.
You may collect the list of enterprises from the relevant office, like municipal corporation. Then go for stratified random sampling.
