Question

A researcher conducted a repeated measures study comparing three treatment conditions. Refer to attached images and tale to answer a to d.

  Mean Std. Deviation N
Treatment I 1.00 1.414 5
Treatment II 5.00 2.345 5
Treatment III 6.00 1.581 5

 

 

In APA format, report the F-ratio related to the treatment effect:

Is this treatment effect significant?

What is the partial η2  value for the treatment effect?

Is this a weak, moderate, or strong effect?
