This is a repeated measures analysis with movement in nine people with Multiple Sclerosis at two timepoints (an intervention was given between pre-test and post-test). The hypothesis was that movement would be greater after the intervention. Look at the output:

14. Which is the most appropriate conclusion:

a) There were six ranks where post-test movement was greater than pre-test movement

b) There were six ranks where pre-test movement was greater than post-test movement

c) There was one rank where post-test movement was greater than pre-test movement

d) There was one tie
