Question

I'm writing a lab report. In the statisticts part in which I'm doing two tailed unnpaired t-test between two groups, If I am comparing the difference between two groups of peop;e on a particular variable, and the number of people in one sample size is only 25 and the number of people in the other group is 1749. Then can I include as a possible source of error that there was such a big difference in the sampling size? How should I explain the source of error? I mean what impact this difference between the two sample sizes can make on my data? The hypothesis is that that there's a difference between the mean weekly study hours between people who exercise regularly and the people who don't, and the null hypothesis is that there's no difference.

Explanation / Answer

Mostly t-test used for small sample test and for large sample you want to use normal two mean test.

But your one sample size is very small as compared to other .

So you get minimum sample size by using SRSWOR sampling technique.

Then you also use t-test and it's hypothesis.
