Two students recently completed their term research projects. Each used a t-test for tow independent groups. One found a significant t using 10 subjects per group, while the other found a significant t of the same magnitude using 45 subjects per group. Which result impresses you more?


I'm thinking the student who only had 10 subjects per group. I'm having a hard time explaining why.

there were more homogenouos in the responses of de 10 subject set i would say...

the 45 subject sample appeared to find more outliers and more residual opinions ...
