group of researchers is studying the effect of exercise on memory. They gather a group of 60 volunteers and place them into 10 groups. 5 of the groups undergo the control trial and then the experimental trial. The other 5 groups undergo the experimental trial and then the control trial. The researchers then analyzed the results. What type of analysis did they perform and what is the n of this experiment? Group of answer choices paired analysis, n = 60 unpaired analysis, n = 60 unpaired analysis, n = 120 unpaired analysis, n = 240 paired analysis, n = 120 paired analysis, n = 240 paired analysis, n = 10 unpaired analysis, n = 10
