Hello there and apologies for my English and lack of statistic skills!
Two different groups of participants, one comprised of children and the other of adults, run once, at different times, the same test with results in the range of 0 to 60 (i.e. discrete values). The number of participants in each group is different but both are larger than 30. The test is a test of Computational Thinking abilities (think IQ), so I think we can safely assume that the distribution is normal.
I have the Min, Max, Avg, and Std Deviation of the results for both groups. I want to know whether adults do significantly better than kids (my bet is on the kids, though :) ).
I THINK I should use the two samples t-test EXCEPT that this source here states that the test is for continuous data (even though the example it describes is for discrete test scores!)
So, should I use the two samples t-test or should I use another one, and if so - which?
