MPEARSON (ArrayOfArrays)

• is the array of two set of independent values.

.

## Description

• This function gives the Pearson Product-Moment Correlation Coefficient.
• It is denoted by PPMC, which shows the linear relationship between two variables.
• It is a measure of the strength of a linear association between two variables .
• The two variables and , giving a value between +1 and −1 inclusive.
• Here
+1 indicates the perfect positive correlation,
0 indicates no correlation
-1 indicates the perfect negative correlation.

• The formula for PPMC, is defined by:

where and are Average of the two Samples and .

• In , the value of must be either numbers or names, array,constants or references that contain numbers.
• Suppose the array contains text, logicl values or empty cells, like that values are not considered.
• This function will return the result as error when the number of values are different for
