AVERAGE()

Arithmetic average of list items

Returns the computed average of the values in a list.

Sample usage

AVERAGE(Products[Price]) : The average of the all values in the Price column of the Products table. Equivalent to AVERAGE(SELECT(Products[Price], TRUE)). See also: SELECT()

AVERAGE([Discounts]) : The average of the all items in the Discounts column value, where Discounts is of type List for some numeric type.

AVERAGE(LIST(1, 2, 3)) : 2.00

AVERAGE(LIST(0) - LIST(0)) (a valid constructed list with a type but no items): 0.00

Average of select rows

Compute average product rating from customer feedback within the past month, excluding feedback with no rating:

AVERAGE(
 SELECT(
  Feedback[Product Rating],
  AND(
   ([Product Rating] > 0),
   ([Submitted] >= (EOMONTH(TODAY(), -2) + DAY(TODAY())))
  )
 )
)

• SELECT(Feedback[Product Rating], ...) gets a list of Product Rating values from select rows of the Feedback table.
• AND(..., ...) limits the SELECT() results to only those rows that match all of the conditions.
• ([Product Rating] > 0) limits the selection to only rows with a Product Rating value greater than zero, where 0 is the default value and indicates "no rating".
• ([Submitted] >= ...) further limits the rows to those with a submission date on or after the computed date.
• (EOMONTH(TODAY(), -2) + DAY(TODAY())) computes the date one month prior to today.
• AVERAGE(...) computes the average of the selected values.

Common problems

AVERAGE(1, 2, 3) : the arguments are not in list form. To fix, wrap them in LIST() to construct a list: AVERAGE(LIST(1, 2, 3)).
