Complete: Chapter 1 Problem Set Due Today at 11:59 PM EST 3. Dependent and independent variables Aa Aa studies consist of two or more groups of scores being compared. For each, decide whether the study is experimental or nonexperimental, and then identify the dependent, independent, or quasi-independent variables. Fourth-grade classrooms in several elementary schools are randomly assigned to different antibullying training programs at the beginning of the school year. The school district keeps track of the number of incidents of bullying in each classroom This study is an example of study The type of training program is the variable. The number of incidents of bullying is the variable. Researchers at a school of public health conducted a study to test the effect of organic produce on cancer mortality The 400 patients with prostate cancer who volunteered for the study were randomly assigned to a diet of either organic or length of time each patient survived I produce. The progression of their cancer was monitored, and researchers documented the This study is an example of study The survival time is the variable. The type of diet is the variable.

Explanation / Answer

Part 1

This study is an example of experimental study.

The type ot training program is the independent variable. The number of incidents of bullying is the dependent variable.

Explanation : Since the subjects of our study(the fourth-grade children) are being directly altered in the study by giving ot not giving the antibullying training,the study is an experimental study.

An independent variable is one which is controlled or altered in some manner to test the effects on some other variable, namely, the dependent variable. Since here we are controlling whether or not to give antibullying training, the type of training program is our independent variable and since we are meauring its effects on the no. of bullying incidents, it is our dependent variable.

Part 2

This study is an example of experimental study.

The survival time is the dependent variable. The type of diet is the independent variable.

Explanation : Since the subjects of our study(the prostate cancer patients) are being directly altered in the study by giving the organic or conventional produce,the study is an experimental study.

An independent variable is one which is controlled or altered in some manner to test the effects on some other variable, namely, the dependent variable. Since here we are controlling whether to give a diet of organic or conventional produce, the type of diet is our independent variable and since we are meauring its effects on the survival time, it is our dependent variable.
