Help: Correlations

Correlation is a measure of how one variable affacts another. The correlation between two variables can vary from +1.0 to -1.0, with +1 indicating perfect correlation, and -1 showing perfect inverse correlation. A value of zero indicates that there is no correlation between the two variables.

Correlation values are not meaningful until at least 10 data points are entered. The larger the data sample, the more accurate are the results.
