Correlation and Regression

This clip describes what correlation represents and how to use a graphing calculator to determine what the correlation of a set of data. It also provides steps for graphing scatterplots and the linear regression line, or best-fit line, for your data. Residuals are also explained as well. Most of the examples are done on the calculator.

If correlation, r does not show up in the screen where it should, the following steps must be done:
1) Push the 2nd key, followed by the number 0 (which should take you to the catalog).
2) Press the x-1 (located under the math key) This will take you to the "d"s of the catalog.
3) Arrow down to the DiagnosticOn option and press ENTER.
4) Once that takes you back to the homescreen, press ENTER again. The screen should say "done". Now when you bring up the LinReg info, r should be listed.
