Frequency Tables + Bar Graphs

A frequency table is a way to organize data that shows how often each value occurs.

A bar graph is a visual representation of data using bars to show the quantity of different categories.

Add up all the frequencies in the table.

Each bar represents the quantity of a specific category.

You can compare the heights of the bars to see which category has more or less.

The title explains what the graph is about.

Look at the labels on the x-axis and y-axis to understand what is being measured.

It means that the category represented by the taller bar has a greater quantity.

Subtract the smaller frequency from the larger frequency.

Labeling axes helps to clarify what each axis represents, making the graph easier to understand.
