Among adults between the ages of 40 and 55, is there a difference between males and females in social networking, as measured by number of minutes on Facebook during a one-month span?

a. Identify the independent variable (IV) and levels of the IV. If appropriate label the control group and the experimental group. b. What scale of measurement is used for the IV? c. Identify the DV by giving both its construct and its operational definition. Be sure to label the construct and operational definition. d. What scale of measurement is used for the DV? e. Identify the research design.

Solutions

Expert Solution

a. Identify the independent variable (IV) and levels of the IV. If appropriate label the control group and the experimental group.

-> The independent variable is gender of the adult. There are 2 levels independent variable - Male and Female

b. What scale of measurement is used for the IV?

-> The scale of measurement used for independent variable in this case is Nominal.

c. Identify the DV by giving both its construct and its operational definition. Be sure to label the construct and operational definition.

-> The dependent variable in this case is number of minutes an adult uses on Facebook during a one month span.

d. What scale of measurement is used for the DV?

-> The scale of measurement used for depedent variable is Interval scale.

e. Identify the research design.

This is an observational study with correlational research design.

An organization believes that the thought of adults ages 55 and over on which industry has the most trustworthy advertising is uniformly distributed. To test this claim, you randomly select 800 adults age 55 and over and ask each which industry has the most untrustworthy advertising. The results are shown in the table. At a = 0.05, can you reject the claim that the distribution is uniform ( ie, that each frequency should be the same - in this case,...
