Question

In an experiment, 10 participants were given a test of mental performance in stressful situations. Their scores were 2, 2, 4, 1, 4, 3, 0, 2, 7, and 5. Ten other participants were given the same test after they had been trained in stress-reducing techniques. Their scores were 4, 4, 6, 0, 6, 5, 2, 3, 6, and 4. Do the appropriate t-test to determine if the group that had been trained had different mental performance scores than the group that had not been trained in stress reduction techniques. What do these results mean?

Hint: Begin by entering all of the scores in PSPP and assigning your experimental group and control group!

 

  1. What is the control group standard deviation? (report to 2 decimal places, so x.xx)

 

  1. What was the T-score? Make sure you give any sign indicators necessary and report to 2 decimal places (so, x.xx or -x.xx).

 

  1. What was the t score? Make sure you give any sign indicators necessary and report to 2 decimal places (so, x.xx or -x.xx).
