An Investigator attempted to ascertain effects of hunger on aggression in cats. She took 10 cats, kept them in individual cages, and put them on a food deprivation schedule such that at the end of two weeks the cats weighed 80% of their normal body weight. She then put the cats in pairs for 15 minutes and watched to see if aggression or fighting would occur. In all cases, the cats showed the threat posture, and in most cases fighting occurred. Concluded that hunger increases aggression in cats. a. What are the experimental units? b. What is the explanatory variable? c. What is the response variable? d. What is the interacting variable? e. What is the population? f. Who is the control group? g. What is the dependent variable?

Consider the following explanation

Step-by-step explanation:

The experimental unit here is a cat.

The explanatory variable is a numerical variable which identifies the time for which a given cat is subjected to hunger deprivation.

The response variable is a categorical variable which identifies whether there is an increase in aggression in a given cat.

The interacting variable is a numerical variable where weight of a given cat is noted.

Population here is the 10 cats.

There is no control group for the given experiment.

Dependent variable is the weight of each cat as it changes as the experimental units are subjected to hunger deprivation.
