Dot Plot

A dot plot is a simple way to display data using dots to represent the frequency of values.

You count the number of dots above each value to see how many times that value occurs.

Each dot represents one occurrence of a value in the data set.

Add up all the dots in the plot.

The mode is the number that appears most often in a data set.

Look for the value with the most dots above it.

A tall column means that many items share that value.

A short column means that few items share that value.

You draw a new dot above the value that you want to add.

The range is the difference between the highest and lowest values.
