Dot Plot Worksheets

A dot plot is a visual way of recording data values.

A line plot is another name for a dot plot.

Dot plots are useful for displaying small amounts of data in discrete bins (categories).

The dot plot above, shows the number of goals scored by a soccer team in the matches they played.

Using a dot plot, we can also work out:

• the range of the data set by subtracting the minimum value from the maximum value;
• In the example above the range of goals scored is 6 - 0 = 6 goals.
• the median can be found by working out the number of data points and then finding the middle one;
• In the example above, there are 15 matches played in total. The middle match is the 8th. The number of goals scored in this match was 3.
• the mean can be found by adding up all the values and dividing by the number of values.
• In the example above, the total goals scored is 0 + 1x2 + 2x4 + 3x3 + 4x1 + 5x2 + 6x2 = 45. The number of matches is 15. So the mean is 45 ÷ 15 = 3 goals per match.

These sheets have been designed for students around 6th grade level.

We have split our worksheets into two sections:

• creating dot plot worksheets;
• interpreting dot plot worksheets.

These sheets involve the following:

• using the information to draw a dot plot on the number line provided.
• putting a data set in order;
• finding the median value;
• finding the range;
• finding the mean value;

These sheets involve answering a range of questions about the dot plot, including:

• identifying the minimum and maximum values;
• identifying the median value.
• finding the range;
• finding the mean value..

Using this webapge will help you to:

• find the median of a set of data;
• find the median of both odd and even numbers of data points;
• show you worked examples of how to find the median.

The sheets in this section will help you to find the mean of a range of numbers, including negative numbers and decimals.

There are a range of sheets involving finding the mean, and also finding a missing data point when the mean is given.

The sheets in this section will help you to find the mode and range of a set of numbers, including negative numbers and decimals.

There are easier sheets involving fewer data points, and harder ones with more data points.
