Question #5: Educational psychologists were interested in the impact the "Just Say No!" Program and contracts on drunk driving among males vs. female teenagers. With the cooperation of school officials, 16-year-old students were matched and randomly assigned to one of two groups, with equal numbers of males and females in each group. Group A participated in a "Just Say No!" program, which required a one-hour information session instead of P.E. for six weeks. Students were presented with written factual information, motivational lectures, guidance films, and assertiveness training. Students were also encouraged to sign a personal responsibility contract that stipulated that they would not drink and drive. Group B participated in regular P. E. classes for the six-week experimental period. Please answer the following questions and justify your answer.

(a) Identify the experimental design.

(b) What is the independent variable? Quasi-independent variable? What is the dependent variable?

(c) Diagram this experimental design.

(d) State at least one potential confounding variable?

(e) How many main effects, interaction effects, simple main effects of A, and simple main effects of B are there?

Expert Solution

A) The design of this study is experimental design study as it has a control group and an experiment group.

B) The independent variable is the showing of movies, speeches, and positive stimulus in experiment group; the quasi independent variable would be the gender for the two groups; and the dependent variable is the impact on behavior vis à vis drinking and driving.

C) Your design will go in a horizontal flow chart structure, where you will let start with number of participants branching out into two groups and the two groups further branching out into their respective IVs and then DV, if any impact found.

D) Confounding variable could be personal characteristics, where some people are already of the belief that it shouldn't be done. Or confounding variable here could also be not owning a car.

E) For group A there are 5 main effects (ranging from provision of factual information to signing of personal accountability contract). The interaction effect is 6 in number with each subset of independent varibale influencing the other and on the dependent variable. For group B there is just one main effect which is PE.

A group of I-O psychologists were interested in whether listening to the radio or an audio book while working would result in greater productivity of factory workers (defined by pounds of product produced). Therefore, the researchers visited a factory in Pennsylvania that has 10-full-time employees. They first recorded the pounds of product produced by each employee while listening to a local music radio station on Wednesday of week 1. Then on Wednesday of week 2, the researchers recorded the pounds...

The Yale program of affairs is interested in understanding student perspectives of their educational experience and has tasked you with taking a look at the problem. You have obtained data from your school as well as several other schools that offer a Program of Affairs that includes the type of curriculum (traditional on-campus versus non-traditional online), and the student’s evaluation of the course(low versus high). You also have data for a third variable, which includes the emphasis of the course of study(quantitative...

Assignment Question Sensation and Perception: Signal Detection Psychologists have always been interested in the relationship between physical stimuli and the cognitive interpretations of the sensations and perceptions these stimuli produce. This field of study is called psychophysics. One of the major contributions of psychophysics is signal detection theory (SDT). The concepts behind SDT had a very practical beginning. They were first developed as a way to help the military pick the best sonar and radar operators during World War II....

Suppose you are interested in understanding the causal impact of having an MBA (versus just an undergraduate degree in business) on earnings. To this end, you estimate a regression of the following form: EARNINGS = 55679 + 27809(MBA) The estimated coefficient above suggests that individuals with an MBA earn $27,809 more than those with just a business undergraduate, on average. Give an example of how omitted variable bias might impact this estimate

Question 2 Suppose a researcher is interested in the effectiveness in a new childhood exercise program implemented in a SRS of schools across a particular county. In order to test the hypothesis that the new program decreases BMI (Kg/m2), the researcher takes a SRS of children from schools where the program is employed and a SRS from schools that do not employ the program and compares the results. Assume the following table represents the SRSs of students and their BMIs....
