PEARSON versus CORREL
The help text for these two functions sure looks similar (in Excel
2003). Are they in fact the same function, or is there some difference between them that I'm missing?

Answer: PEARSON versus CORREL
Hi Stan,
While PEARSON and CORREL may seem similar, they are actually two different functions in Excel. PEARSON is used to calculate the Pearson correlation coefficient between two sets of data. This coefficient measures the strength and direction of the linear relationship between two variables. The result of PEARSON will always be a value between -1 and 1, where -1 indicates a perfectly negative correlation, 0 indicates no correlation, and 1 indicates a perfectly positive correlation. On the other hand, CORREL is also used to calculate the correlation coefficient between two sets of data, but it can handle multiple sets of data at once. The result of CORREL is also a value between -1 and 1, but it can be an array of values if multiple sets of data are used. In summary, PEARSON is used for calculating the correlation coefficient between two sets of data, while CORREL can handle multiple sets of data at once.

I wonder: why there were two functions with different implementations to do the same thing? -- Stan Brown, Oak Road Systems, Tompkins County, New York, USA http://OakRoadSystems.com/ "If there's one thing I know, it's men.
