Question

A team of communication scholars conducted a study on the effects of media consumption on aggressive behavior. Forty-eight subjects stayed in a lab for two days. Twenty-four of the subjects are randomly assigned to a condition in which they are not permitted to consume any media that period. The other twenty-four are allowed to consume media whenever they want. At the end of the two days, the subjects finish a task that involves viewing the same tv episode, then identifying as many aggressive behaviors as possible.

For each of the studies, please indicate the following:
1. What is the independent variable? The effects of media consumption
2. Is there more than one IV? Abstinence from Media Consumption and Media Consumption Continued Use
3. Is the IV a continuous or categorical variable? See Above
4. What is the dependent variable? (for correlation, list all variables here and ignore the IV questions)
~ The dependent variable is aggressive behavior
5. Is the DV a continuous or categorical variable ? Continuous ~ measured numerically, has an infinite number of possible values
6. What type of design is being used? Experimental Design
7. What is the appropriate statistical test given the types of variables in this example?

Answer 1

A.) The Independent variable is media consumption. ;

B.)

1.) Abstinence from media consumption

11.) Continued consumption of media

C.)

Categorical Variable ;

D.)

Dependent variable is Aggressive behavior ;

E.)

The dependent variable is a continous numerical variable

F.)

Experimental Design.

Explanation:

The Independent variable are those variables which causes a change in the measured or dependent variable.

The dependent t variable is the measured variable whose change is triggered by the independent variable.

Categorical Variables are non-numeric labels while the quantitative variables are numeric labels.

Experimental designs usually divides subjects into two or more treatment groups whrebt the effects of applied treatment is observed across the different groups.
