Researchers wish to see if eye color is related to how attractive a person is perceived to be. They take a photograph of a blue-eyed confederate and then create a second version of the picture by altering his eye color to brown. They randomly assign each participant to one of two groups. One group views the photo in which the confederate has blue-eyes, and the other group views the photo in which the confederate has brown eyes. Each participant rates the person in the photo on a 1-10 equal-interval scale for attractiveness. Does the eye color of the person in the photo influence attractiveness ratings? Which is best to use when testing for this difference?

a. ANOVA

b. Single Sample T

c. Correlation

d. Paired Sample T

e. Independent-Samples T

Researchers believe that IQ scores may have less to do with intelligence and more to do with being socialized in a manner typical of the dominant culture. They recruit a sample of children who are being raised in the US, but meet the researchers' criteria for classification as being socialized in a manner that is inconsistent with the dominant culture. Among possible criteria might be that these children do not watch television!!!! (Really... what kind of person would do something like that to their own child!) To test their hypothesis, researchers wish to compare this sample's average IQ test score to the national average. Which is best to use when testing for this difference?

a. Independent-Samples T

b. Paired-Samples T

c. Correlation

d. ANOVA

e. Single-Sample T

Researchers want to know if there's a relationship between monthly salary earned by people and the amount of money people spent on recreation each month. Perhaps people who earn more money tend to save more and spend less, or perhaps people who earn more money go out and spend more frivolously. How will researchers test for a relationship between these two variables?

a. Independent-Samples T

b. Single-Sample T

c. Correlation

d. ANOVA

e. Paired-Samples T

A forensic psychologist conducted a study to examine whether being hypnotized during recall affects how well a witness can remember facts about an event. Eight participants watched a short film of a mock robbery, after which each participant was questioned about what he or she had seen. The four participants in the experimental group were questioned while they were hypnotized and gave 14, 22, 18, and 17 accurate responses. The four participants in the control group were questioned while NOT under hypnosis and gave 20, 25, 24, and 23 accurate responses.

Researchers wish to test for the effect of a program designed to reduce drinking behavior among young adults. They get an initial measure of the number of drinks typically consumed by each participant on an average Saturday night. Participants then take part in the experimental program. When the program is completed, the researchers take another measure of the typical number of drinks consumed by each participant on an average Saturday night. Has the program decreased drinking? Which is best to use when testing for this difference?

a. ANOVA

b. Correlation

c. Single-Sample T

d. Independent-Samples T

e. Paired-Samples T

A researcher is interested in the effects of post-traumatic stress disorder treatments. Volunteers with PTSD are randomly divided into three groups. One group is a control group, and their "therapy" consists of simply talking to an experimental confederate about everyday subjects. Another group participates in a type treatment that might generally be considered Humanistic. Another group participates in a type of treatment that might generally be considered Cognitive-Behavioral. Each participant is then rated for symptom severity on a 1-10 scale, with higher scores indicating greater severity

An educational psychologist wants to see if there is a difference in math test scores between male and female children. The psychologist administers a standardized test to a small group of participating children. What analysis should be used to look for a difference between males and females?

An organizational psychologist wants to know if workers' health would be impacted if they were given extra days off. The head of a local company invites the psychologist to work with consenting participants from his plant. All plant workers take a standard physical exam twice a year and are given an overall health rating with higher scores indicating better health. The psychologist selected five workers at random, arranged to have them receive an additional 2 days off every month over the period between health exams, and then compared the health scores on the two exams.
