A sample of difference scores has a mean of 5 with a variance of 100.  If effect size is measured using Cohen’s d, what is the value of d?

A characteristic, usually a numerical value, that describes a sample is called a ____.

Which combination of factors is most likely to produce a small value for the F-ratio?

An independent-measures research study compares three treatment conditions using a sample of 5 in each treatment.  For this study, the three samples have SS1 = 10, SS2 = 20, and SS3 = 15.  What value would be obtained for MSwithin?

A population has SS = 100 and s2 = 4.  What is the value of Σ(X – M) for the population? Hint: Think about what these symbols imply, you are summing the deviation scores. What does this always equal?

For a population with µ = 80 and s = 6, what is the z-score corresponding to X = 68?

What is the value of SS for the following set of scores?  Scores:  1, 1, 4, 0

What is the sample variance and the estimated standard error for a sample of  n = 9 scores with SS = 72?

A researcher uses an anonymous survey to investigate the study habits of American college students.  The entire group of American college students is an example of a ____.

calculate the z score if X = 75 µ = 70 and standard deviation = 2
