Based on the following repeated measures ANOVA output, and presuming we met all the assumptions of the test, we can conclude that: Tests of Within-Subjects Effects Measure: MEASURE_1 Source Condition Sphericity Assumed Greenhouse- Geisser Huynh-Feldt Lower-bound Error(Conditio Sphericity Assumed Greenhouse- Geisser Huynh-Feldt Lower-bound Type III Sum of Squares 83.125 df 3 83.125 1.599 83.125 1.997 83.125 1.000 153.375 21 153.375 11.190 153.375 13.981 153.375 7.000 Mean Square 27.708 52.001 13.707 F 3.794 41.619 3.794 83.125 3.794 7.304 10.970 21.911 3.794 Sig. 026 .063 .048 .092 Partial Eta Squared .351 There is a significant difference between conditions with a large effect size. Some conditions differ, but others do not. But the effect size is small. There is not a significant difference between conditions, but the there is a medium effect size. 351 .351 .351
