## How to Create a Scatter Plot in Excel

A scatter plot may very well be the most useful creation in the history of statistical graphics. The creation of the scatter plot by Galton led to the use of correlation and regression in the field of statistics.

Scatter plots can tell you a lot about a data set. The data set for a scatter is created from events that relate to two variables. Each piece of data in the data set represents a point on the scatter plot. Creating a scatter plot is a great way to find out whether two variables have a relationship and can also measure how close that relationship is. In this tutorial, we use Excel to automatically generate each point on a scatter plot graph.

Below is a practice data set to conduct an analysis. Even without discussing background information about the data, it is still possible to figure out how closely related the two variables are within a scatter plot just by looking at the resulting graph.

Let’s run through an example in Excel to highlight the steps used to create a scatter plot.

## Inserting a Scatter Plot

There are several steps to inserting a scatter plot into an Excel worksheet listed below:

1. First, select the data that you wish to plot.
2. Next, choose the Insert tab and click on the insert scatter or bubble chart option noted by 3 in the illustration below.
3. Finally, select the scatter chart option.

Each of these steps can be seen in the illustration below.

## Displaying Chart Elements of a Scatter Plot

Notice the green cross to the right of the scatter chart that appears after the chart is selected. Click on this button to show the chart elements options. The list of elements allows you to change the appearance of your graph by adding them to the chart or removing them.

The elements that can be added or removed from a scatter plot are:

• Axes
• Axis Titles
• Chart Title
• Data Labels
• Error Bars
• Gridlines
• Legend
• Trendline

Any of the above chart element options can be displayed by clicking on the check box next to each option. Each chart element is further explained in the text below.

## Show Axes

The axes are shown on the graph by default. You have the option to remove this option if you wish. When the axes are removed, essentially, you are removing the measurements for the X and Y axes.

## Show Axis Titles

When axis titles are displayed, the labels can be edited for each axis by double-clicking on these text boxes.

## Chart Title

The chart title is set to display by default. This can be removed by unchecking the check box beside “Chart title” or by right-clicking on the chart title and then clicking delete. To edit the title, double-click the text box it resides in.

## Showing Data Labels

A data labels option is available to show data for each data point. By default, the y-axis position data points are displayed when this option is selected.

## Displaying Error Bars

Error bars can also be displayed by checking the box next to that option to indicate the uncertainty of data points on the chart.

## Gridlines

This option allows you to either add or remove the line in the background of the chart.

## Displaying the Legend

Adding the legend allows you to identify the plot point and trendline designs in the chart.

## Show Trendline

The trendline option will display a trendline based on a regression of all the data in the scatter plot. Sometimes when viewing a scatter plot, the relation between the variables is not apparent. A trendline can tell you three things:

• Whether the data is inversely related when the trendline slants down from left to right.
• whether the data has a direct relationship when the trendline slants up from right to left.
• Whether the data has no relationship when the trendline is a flat line.

## Formatting the Trendline

The trendline offers additional options. A few options that benefit analysis of your data set are the options to display the regression equation for the data and the R-squared value on the chart. To complete this task, click on the chart, then click on the arrow to the right of the trendline option.

## Adding the Slope Equation & R-Squared

To add the regression equation and R-square value click on the check boxes shown in the illustration below.
