How can we determine the sample size from an unknown population?

06 June 2018 1 6K Report

My research involves upper limb and lower limb driving disabled people in my country. So what would be a reasonable sample size in this case since I can not readily quantify how many disabled people by region in my country.

Caleb A. Aldridge

It depends on what you're intending to know, e.g., a response of disabled people or a proportion within the population? The following might be helpful.

Cheers,

Caleb

What test should I use to compare two or three means, if data is not normally distributed but sample size is > 30 in each group?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...
