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.
- Use PEARSON to calculate the correlation coefficient between two sets of data.
- Use CORREL to calculate the correlation coefficient between multiple sets of data.
