Solution

Bar charts are used to graph:

a. numerical data b. ordinal data c. categorical data d. cardinal data

The correct answer is c. Categorical data.

Here's why:

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.

a. Numerical data: This is not the best answer because numerical data is often better represented by line graphs or scatter plots, which can show trends over time or relationships between variables.

b. Ordinal data: This is not the best answer because ordinal data, which involves a set order of values (like "first, second, third"), is often better represented by a line graph, which can show the order of categories.

d. Cardinal data: This is not the best answer because cardinal data, which involves values that have a meaningful zero point (like temperature in degrees Celsius), is often better represented by a line graph or scatter plot, which can show trends over time or relationships between variables.
