The sum of the squared deviation scores is SS = 20 for a sample of n = 5 scores.  What is the variance for this sample?

When n is small (less than 30), how does the shape of the t distribution compare to the normal distribution?

For an independent-measures research study, what is measured by Cohen’s d or r2?

Using z-scores, a population with µ = 37 and σ = 6 is standardized so that the new mean is µ = 50 and σ = 10.  After the standardization, one individual has a score of X = 55.  What was this individual’s score in the original distribution?

A population with a mean of µ = 6 has ΣX = 42.  How many scores are in the population?

When n is small (less than 30), how does the shape of the t distribution compare to the normal distribution?

Which of the following represents the strongest correlation?

A sample of n = 8 scores has a mean of M = 10.  After one score is removed from the sample, the mean for the remaining score is found to be M = 11.  What was the score that was removed?

You are instructed to subtract four points from each score, square the resulting value, and find the sum of the squared numbers.  How would this set of instructions be expressed in summation notation?

Which of the following is an example of a discrete variable?
