Question

We wish to assess the effect of three different track surfaces on sprinter speed. Six world-class sprinters are asked to run five 100m dashes on each of the three track surfaces. Their average times are recorded below. Surface1 Surface2 Surface3 Sprinter 1 9.85 10.00 10.04 Sprinter 2 9.90 10.07 10.16 Sprinter 3 9.89 9.99 10.17 Sprinter 4 9.88 9.98 10.04 Sprinter 5 9.81 10.03 10.10 Sprinter 6 9.81 9.95 10.12 Using the sprinters as blocks, discuss the differences between the track surfaces as suggested by SPSS. Give a statement to be tested, identify the random variables involved and the assumptions you make about them, state the hypotheses to be tested, ask SPSS to run the analysis for you, including a post hoc, and then discuss the outcome. Describe the critical region(s) upon which you base your decisions. Include any SPSS output in your discussion. Not by hand or excel. Post screen shots of step by step process of how you got the answer.
