The display summarizes the type of pets among customers at a pet store. A bar chart is shown with 5 vertical bars, with quantity on the vertical axis and pets on the horizontal axis. The bar labeled dogs extends to 43, cats to 34, fish to 16, birds to 4, and rabbits to 2. Which of the following describes the data set?

1) The data is bivariate and categorical.
2) The data is univariate and numerical.
3) The data is univariate and categorical.
4) The data is bivariate and numerical.

Answer 1

The bar chart representing different pet types and their quantities in a pet store describes a univariate and categorical data set, as it deals with one qualitative variable, the type of pets.

Step-by-step explanation:

Looking at the given description of the bar chart displaying pet types and their quantities, we can analyze the characteristics of the data.

A bar chart is a visual representation where the length of the bar for each category corresponds to the number or percentage of individuals in each category.

In this case, the bars represent different pet types (dogs, cats, fish, birds, and rabbits) and the height of each bar reflects the quantity of each pet type owned by customers of a pet store.

The correct description of the data set is univariate and categorical.

This is because the data represents a single variable (the type of pets) which is a qualitative or categorical variable and not a quantitative or numerical one, even though it comes with a count of individuals, the count (number of pets) simply provides the frequency of each category and does not represent a separate variable.
