Question

A store asked 250 of its customers whether or not they were satisfied with the service. The responses were also classified according to the gender of the customers. We want to study whether there is a relationship between satisfaction and gender.

A meaningful display of the data from this study would be:

a) side-by-side boxplots
b) a pie chart
c) a histogram
d) a scatterplot
e) a two-way table

Answer 1

Correct option: e) a two-way table.

Explanation:

In this case the store wants to see whether there is a relationship between the satisfaction level of the customer and their gender.

In statistics when there is a need to analyze or derive a relation between two categorical variables one should use a two-way table.

Categorical variables are qualitative variables that take on specific values that are usually labels. For example, grades obtained in an exam, gender, etc.

In this case the two categorical variables are: Gender and Satisfaction level.

To study the relation between the gender of a customer and their satisfaction level use a two-way table.
