Statistical Functions
Statistical functions perform statistical calculations and require numeric expressions as 
arguments. The numeric expression can be a number, cell reference, or range. Unless 
otherwise stated, statistical functions result in a number.
Numbers provides these statistical functions.

Description
Calculates the average difference (deviation) of data points from 
their arithmetic mean (average).
Calculates the average (arithmetic mean) of a set of numbers.
Calculates the average (arithmetic mean) of a set of values 
including numbers, text, and Boolean values.

Calculates the covariance of two data sets.
Calculates the y (dependent) value that corresponds to a chosen x 
(independent) value by using linear regression analysis of known 
value pairs.
Calculates the y-intercept of the best-fit line for a data set using 
linear regression analysis.
