The following data represent the results from an independentmeasures experiment comparing three treatment conditions. Use SPSS to conduct an analysis of variance with or = 0.05 to determine whether these data are sufficient to conclude that there are siinificant differences between the treatments. Treatment A Ti'eatment B Ti'eatment C F-ratio= 11.66? X Conclusion: (9 There is a significant difference between treatments CI These data do not provide evidence of a difference between the treatments The results obtained above were primarily,r due to the mean for the third treatment beng ndtiCeablgir different from the other two sample means. For the following data, the scores are the same as above except that the difference between treatments was reduced by moving the third treatment closer to the other two samples. In particular, 3 points have been subtracted from each score in the third sample. Before 1you begin the calculation, predict how the changes in the data should influence the outcome of the analysis. That is. how will the F-ratio for these data com -are with the F-ratio from above? Treatment A Treatment Treatment C -- --E-- - --'--E- 5 7 3 Fratio= \"11.671 x
