Scatter Diagrams / Correlation

[M]

Hi,

Is it possible to draw scatter diagrams on Autograph and/or calculate correlation co-efficients etc.?

I only have the 30-day demo version - is this an issue?

Thanks for your help, Michael.

Hello

To draw a scatter diagram right-click on a 2D Graph page and select \'Enter XY Data Set\'. Enter your data in the two columns provided. Before you click OK make sure that the \'Show Statistics\' checkbox is ticked. This will display a box containing various statistics of the data including correlation coefficients etc.

You can also select the data once you have entered it by clicking on one of the points. This allows you to draw regression lines and polynomial best fits etc. These are again selected from the right-click menu.

Hope this helps.
