Dot Plot Review

A dot plot is a simple way to display data using dots above a number line, where each dot represents one data point.

The range is found by subtracting the lowest value from the highest value in the data set.

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

Count the number of dots to the right of the specified score on the dot plot.

The median is the middle value when the data points are arranged in order.

You interpret a dot plot by looking at the number of dots above each value to understand the frequency of each score.

Dot plots help visualize the distribution of data and make it easier to see patterns and trends.

Add up all the dots in the dot plot to find the total number of data points.

A peak in a dot plot indicates the mode, or the most common value in the data set.

If the dots are concentrated on one side of the plot, the data set may be skewed.
