To investigate serotonin’s role in suicidal behavior, the amounts of serotonin metabolites in the cerebral spinal fluid of 18 violent-suicide attempters are compared to the levels found in a group of 24 nonviolent-suicide attempters. The levels of serotonin metabolites are coded as low or normal/high, and the two groups are compared. These data would most appropriately be analyzed with a(n):

Why do correlation coefficients greater than 0.50 rarely occur in the social sciences?

The campus teaching and learning center is conducting a study to determine the relation between method of presentation (standard lecture versus computer presentation) and type of lecture (psychology, economics, statistics, or computer science) to lecture comprehension. How would we describe the design?

When the within-groups variance is much larger than the between-groups variance, we infer that the sample means are _____ one another, and we _____ the null hypothesis.

According to guidelines published by Cohen (1988), a correlation value of 0.34 would be considered:

According to conventions, an ω2 of 0.002 is considered to be a _____ effect size.
