I used t-tests because I wanted to compare two means and I wanted to compare the before and after effect of the stretching intervention on hockey performance, therefore I used a paired t-test. I also used a paired t-test on the control group to see if there was a significant difference there. Figure 4. Graph showing the change in sprint performance (seconds) during baseline and post-training testing in the experimental and control groups.

A paired t-test established a significant difference between the average results of baseline and post training for the power test in the experimental group, t (8) = -5.63, p = 0.00. A paired t-test established an insignificant difference between the average results of baseline and post training for the power test in the control group, t (9) = 0.71, p = 0.49. Step 2: Random allocation of participants to an xperiment l or control group Step 3: Consent from participants to their role in the experiment using the PAR-Q Step 4: Baseline tness tests for all participants 33.00 Agility 31.00 32.00 30.00

A paired t-test established a significant difference between the average results of baseline and post training for the speed test in the experimental group, t (8) = 7.63, p = 0.00. A paired t-test established an insignificant difference between the average results of baseline and post training for the speed test in the control group, t (9) = -1.46, p = 0.18. 28.00 Power 27.00 27.50 26.50
