Remarks
Use the correlation coefficient to determine the relationship between two properties. For example, you can examine the relationship between a location's average temperature and the use of air conditioners.
If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
If Arg1 and Arg2 have a different number of data points, Correl generates an error.
If either Arg1 or Arg2 is empty, or if s (the standard deviation) of their values equals zero, Correl generates an error.
The equation for the correlation coefficient is as follows, where x and y are the sample means Average(Arg1) and Average(Arg2):
