Question
8. (10 points).Are cuteness and aggression related? A study done Yale University tested this by showing people pictures of cute animals (like kittens and puppies) and pictures of older more serious looking animals. They tested the aggression of the subjects by giving them bubble wrap and let them pop the bubbles. The subjects in the group shown the cute animals popped an average of 120 bubbles compared 100 for the group seeing the pictures of the older animals. gel quantitative. Explanatory variable? Explanatory variable type? Response variable? Response variable type?Explanation / Answer
Explanatory variable is the independent variable in the experiment. It is the variable that is influenced or changed by nothing and is something manipulated by the experimenter/researcher.
In our case, the explanatory variable is the picture shown. The picture shown can be either cute or serious.This is categorical as the type of the explanatory variable is the type of picture shown which is either cute or serious. There is no numeric or quantitative value attached to these.
Hence, explanatory variable = Picture of animal and Explanatory variable type = Categorical
The response variable is simply the number of bubbles popped on average on seeing the picture. This will be a number as the number of bubbles popped will have to be a number like 100 or 120.
Hence, response variable = number of bubbles popped on average and Response variable type = Quantitative
