How to interpret the Pearson Correlation Index?

  1. Dec 11, 2015 #1
    Not sure if that's the technical name, but I refer the the number Excel give you between 0 and 1 when you use the "correl" command on two sets of numbers.

    It is an indicator of the tendencies of the two variables to move in the same direction, and a sufficient, but not necessary, indicator of dependence. The closer its absolute value is to 1, the stronger the indication of dependence. If the number is positive (negative) it indicates a how often the variables move in parallel (opposite) directions.
