Question

An administrator at a university wants to determine if there is a relationship between gender and selected major. Assuming that data has been collected on these variables, why would a scatterplot be inappropriate?

a.This relationship would be weak.
b.Both variables are categorical.
c.Both variables are quantitative.
d.A scatterplot would be appropriate.

Answer 1

A scatterplot would be inappropriate for examining the relationship between gender and selected majors as they are both categorical variables, not quantitative, which is what scatterplots are best suited for.

Step-by-step explanation:

When considering the relationship between gender and selected major, a scatterplot would be inappropriate because this type of plot is ideal for displaying a relationship between two quantitative variables. However, both gender and selected major are categorical variables, not quantitative. Scatterplots depict individual data points on an x and y-axis which help in assessing the potential correlation between quantitative variables. When dealing with categorical data, other visual representations such as bar charts, mosaic plots, or chi-squared tests are typically used to examine the relationships or differences between the categories.
