Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Open the file contained within the folder name shown above.

Select all the data and press F11 to create a chart.

Change the chart type to a Scatter chart and change the axis scale to start at 20000 and end at 40000.  You might also like to edit the marker and the grid options.  Your Scatter chart should now be similar to this:

The next step is to add a regression Trendline.

Select the scatter chart markers and ask Excel to insert a Trendline:

A linear trendline is a good place to start if you're not sure.

You can display the trendline equation on the chart which can be useful:
