Question

What is the value of F Statistic for Difference? Is that significant at alpha 0.05, 0.01, or both? Do Post-Hoc 'Turkey' and Options Descriptives.

I have provided the attached charts

Answer 1

What is the value of F Statistic for Difference? Is that significant at alpha 0.05, 0.01, or both?

F statistic,F=4.421

p=0.004

when alpha=0.05,p<alpha,Reject Ho

when alpha=0.01,p<alpha reject Ho

significant at both alpha=0.05 and 0.01

when group means are significant we need to know which group means are signiifcant .Do a psot hoc like Tukey

For the group Escitalopram-No treatment,p=0.002,p<0.05 ,p<.01,Group means are significant at alpha=0.05 and 0.01

For the group Escitalopram-Effexor,p=0.050,p<0.05,Group means are significant at alpha=0.05 but not significant at alpha=0.01
