Module 6 Topic 2 Worksheet EXTRA CREDIT Scenario 1 One of my pet peeves is pop paychology books. They usually spout nonsense that is unsubstantiated by science and give psychology a very bad name. As part of my plan to nid the world of popular peychology i did a mi WAFMMAFV WH experiment I look two groups of people who were in relationships and Mean happiness Man happiness randomly assigned them to one of two conditions. One group read the 150 140 famous popular psychology book Women are from Mars and men are from Varus, whereas another group relationship after reading the book they were randomly assigned to read.

Boys of a certain age are known to have a mean weight of 85 pounds (SD = 11.6). A complaint is made about a local state home for children: members of the community believe that the boys living in the state children's home are underled. As one bit of evidence, 25 boys (of the same age) are weighed and found to have a mean weight of 80.94 pounds. a. What analysis is appropriate? b.

Scenario 4. Does the academic staff at the UC psychology department publish differently than the national average of 8 publications per staff member over a 10 year period? A random sample of 5 faculty members was taken from the Psychology department at UC. On average, they publish 11.4 articles per year (standard deviation is 2.41).
