I am conducting a study on the retail e-commerce segment in Nigeria and planning to do quantitative analysis using PLS-SEM [to help test mediating effects] but the population is less than 20 and so is the sample size.
The data type is Primary, collected through survey.
1. Can I do an acceptable/adequate analysis with a sample size of 13 respondents?
2. If no, what are my options to proceed considering population size is limited?
3. Would switching to a qualitative/descriptive approach be an option, and why?
4. What data analysis tool should be most ideal for use in my situation and considering I need to test for mediating effects of variables?
