Small sample sizes don’t invalidate studies. They reduce the statistical certainty, but can still be accurate and there’s formulas for gauging how accurate a given sample size is based off the standard deviation.
The student only part does mean a sampling biase, but that doesn’t invalidate things either. Mostly just limits it such that we can only make the claim for students and not anyone else (but it’s still a meaningful result and provides justification for larger studies).
Nonsense. Small sample size studies are legitimate, there is just an increased margin of error when generalizing to the population. They can absolutely still be significant.
