What is a bar graph?

Back

A bar graph is a visual representation of data using rectangular bars to show the frequency or value of different categories.

How do you read a dot plot?

Back

A dot plot displays data points as dots above a number line, where each dot represents one occurrence of a value.

Back

Categorical data represents categories or groups, while numerical data represents measurable quantities.

Front

How can you compare two sets of data using graphs?

Back

You can compare two sets of data by using side-by-side bar graphs or overlaying dot plots.
