Question

Is it possible for two experiments to be well run with similar sample sizes to get different data?

Short answer

Yes, it is feasible for two well-run studies with similar sample sizes to provide different results.

Step-by-step solution

Introduction

Independent groups denote that the two samples obtained are unrelated in any sense, i.e., sample values from one population are unrelated to sample values from the other population.

The first sample, for example, was selecting in a classroom, whereas the second sample was selecting at a football stadium.

Both samples would clearly be different, and so the data obtained would be different as well, despite the fact that the sample size would be the same.
