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 1-10) 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 04:16 AM.
