Up until now, all of these questions have dealt with univariate data. This next one will challenge you........................
I have devised a method of teaching statistics in an hour that I think is fantastic. I'm going to give a pre-test, teach, and then two weeks later give a post-test to see if students have learned anything.
here are two lists. The first is the pre-test, the second the post-test for the same person (for example, the 30 on the pre-test matches the 29 on the post-test).
Pre Test Pest Test
30 29
28 30
31 32
26 30
20 16
30 25
34 31
15 18
28 33
20 25
30 32
29 28
31 34
29 32
34 32
20 27
26 28
25 29
31 32
29 32
Create information, facts, graphs, knowledge, etc. etc. that will help me decide whether or not my technique is effective in teaching statistics.
