SOLVE WITH SPSS ONLY

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. USE SPSS NO EXCEL NO HAND

Surface 1 Surface 2 Surface 3

Sprinter 1 9.85 10.00 10.04

Sprinter 2 9.90 10.07 10.16

Sprinter 39.89 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.

Since critical value is more than all the differences, there is no significant difference between any of the pairs

To run randomized block design anova in spss, please see the steps below: -

a) Select Analyze > General Linear Model > Univariate

b) Insert dependent and independent variables and also select Tukey as the post hoc test

c) Click Continue and OK

This lab uses three friction carts with different surfaces on the bottom (cork, felt, and Teflon) and a set of masses totaling 1250 g. The carts are pulled with a piece of string attached to a hook on a force sensor, which measures the force of tension in the string. Behind the cart being pulled is a motion sensor. These two devices are used to display and record the string tension and the velocity of the cart as a function...
