Interpreting the Correlation Coefficient
This video will show how to interpret the meaning of the correlation coefficient when a data set is described by a line of best fit.

Correlation Coefficients in SPSS/PASW
A short tutorial on calculating a correlation matrix in SPSS (also known as PASW). Describes the range and strength of associations, as well as positive and negative associations. Also describes the pearson correlation (r), the significance level (p), and the sample size (n).

Using Excel to find the Correlation Coefficient r
This video podcast shows how you can use Microsoft Excel to calculate the Pearson product-moment correlation coefficient, r. This tutorial will explain in details how to use all the formulas in Excel to get to r, rather than explain the short Excel function of correlation coefficient, r.

Find the Correlation Coefficient on Your Calculator (TI83, TI84)
Before you can find the correlation coefficient on your calculator, you must turn diagnostics on. After this, you just use the linear regression menu.

Find value of linear correlation coefficient r.
