Thesis Keith Gale 20137.17 Interpretation of Stage Two independent samples t-testsAs with interpretation for Stage One results, Levene’s test for equality is used todetermine variance of scores for both groups at Stage Two.7.17.1 Interpretation for CSF1A – Starting on time:Eta squared for CSF1A = -1.371²-1.371² + (60 +60 - 2)Eta squared for CSF1A = 0.016An independent samples t-test was used to compare the ‘starting on time’ criticalsuccess factor scores for discrete verses framework projects. There was nosignificant difference in scores for discrete projects (M=0.158, SD=0.014) andframework projects (M=0.161, SD=0.011), t (118) =-1.371, p=0.173). Themagnitude of the differences in the means was small (0.016).7.17.2 Interpretation for CSF1B – Finishing on time:Eta squared for CSF1B = -2.374²-2.374² + (60 + 60 -2)Eta squared for CSF1B = 0.046An independent samples t-test was used to compare the ‘finishing on time’ criticalsuccess factor scores for discrete verses framework projects. There was nosignificant difference in scores for discrete projects (M=0.130, SD=0.047) andframework projects (M=0.148, SD=0.036), t (118) =-2.374, p=0.019). Themagnitude of the differences in the means was moderate (0.046).159
