I do not want all of the answers. If you could just show me (a.) for example, then I can do the rest. Just trying to figure it out because the text is not much help. Thanks!



1.   Consider the study of the effect of a teaching method designed to increase the probability of successful completion of a statistics course on the self-esteem of students in the course.

Again, for the normally distributed known population, the Population M = 63 and the Population SD = 12.

What is the estimated effect size for samples that have completed the treatment and have means of (a) 54, (b) 57, (c) 60, (d) 71, and (e) 78?

For each sample mean, indicate whether the effect is approximately small, medium, or large.


PROBLEM   (Pop1 M – Pop2 M) / Pop SD   Estimated Effect Size   Effect Size

(a)         

(b)         

(c)         

(d)         

(e)

Ok, I get how to do some. For example,

(Pop1 M – Pop2 M) / Pop SD is 54-63=-9
then Estimated Effect Size is -9/12=-0.75
but how do they get the 0.2 for the effect size?


Thanks, I appreciate it!

No idea Alison79, I found that in a solutions manual. I was hoping you'd know how to work it.
