According to CDC, the mean height of adults ages 20 and older is about 66.5 inches (69.3 inches for males, 63.8 inches for females). The mean calculated from your data is 66.3 inches. Which statistical analysis would test if the mean height of your sample data is significantly different from the information CDC provides?

A survey asks the following two questions: "Do you like chocolate ice cream (yes/no)?" and "Would you describe yourself as conservative or liberal?" The survey yields a set of frequency counts. Which statistical test allows you to examine whether ice-cream preference and political beliefs are independent?

Students in PSYC11 are randomly assigned to one of the two groups: a group of individuals who take an open-book final exam or a group with a closed-book exam. The test score for each student is recorded. Which analysis would be helpful to determine whether the open-book policy had an effect on performance?

A researcher uses a driving simulator to measure the amount of time it takes for participants to press the brake pedal in response to obstacles that appear on the road.Participants are randomly assigned to one of three "distraction" conditions: drive while talking on a cell phone, drive while pressing buttons on GPS, or drive while talking to a fellow passenger. Each participant performs the task in only one of the three conditions. What test would determine whether there is a significant effect of distraction type on braking times?

An experimenter examines the effects of study location (library, caf, dorm room) and time of day (morning, night) on test performance. Each participant contributes to only one condition (or cell) in the design. Which analysis should be used to determine whether the study location and time of day have effects on test scores?

Are first-born males happier than second-born males? You find 25 pairs of brothers and give each brother a happiness test. The test provides a quantitative index of life satisfaction that ranges on a scale from 1-100. How would you test for a significant difference between first- and second-born brothers?

A researcher is interested in the association between party attendance and academic performance. A chi-square test is performed on a contingency table relating whether one attended at least one party during the final week (yes, no) and whether one passes PSYC11 (yes, no). The test reaches statistical significance, and the researcher now wants to know the strength of the relationship between the two variables.
