We are currently conducting a qualitative research on the effects of influencer marketing on purchase behavior. However, before that, our panel has suggested to conduct a pre-survey to (1) identify the products endorsed by influencer marketing that students mostly purchase, and (2)the social media platforms that students purchase influencer-endorsed products. The purpose of the pre-survey will help us narrow down our scope based on the results of the pre-survey by focusing on a specific social media platform and product.
Our question is how can we determine the sample size?
Thank you in advance!
I am a bit confused by the order in which you are trying to do things. Is the goal of the pre-survey to determine what you will do in a qualitative study that in turns guides the content of a larger survey? If so, I think this is getting things backwards, because it is the goals of your larger survey that should determine the design of your preliminary qualitative study.
In mixed methods research terminology, it seems like the core of your overall project its an exploratory sequential design (qual --> QUAN). But if you restrict your qual component too much, it will won't effectively inform the QUAN component.
Hello, sir. Thank you for the fast response. The pre-survey will serve as a tool to define the scope of our qualitative research, specifically targeting a particular product and social media platform.
Our panel suggested we conduct a survey that will help us focus on a specific industry and social media platform. The survey asks what products they usually buy and what social media platforms they use to purchase. This data will help us delineate the scope and key focus areas.
Thank you in advance!
RV Krejcie and DW Morgan,Educational and Psychological Measurement, 1970,30:607-610, gave a table to choose sample size. Also MA Hertzog ,Research in zNursing and Health,2008,31:180-191. Suggested that sample sizes should be higher that 40. REGARDS.
