Hello, I have 2 groups of pupils: group A and group B. In group A are 30 pupils and in group B are 32 pupils. Both groups do the same test. How can I calculate whether the marks of group A are significantly better than group B? I know the solution must be easy, but my knowledge of statistics goes no further than the standard deviation. example (scale 110) group A group B 6 5 7 6 8 4 9 7 4 8 6 4 7 7 5 9 8 6 7 3 8 6 7 6 .. .. .. .. Thanks in advance. Last edited by dedemsvaart; February 14th, 2017 at 05:16 AM.
