AVERAGEIFS
The AVERAGEIFS function returns the average (arithmetic mean) of the cells in a given
range where one or more ranges meet one or more related conditions.
AVERAGEIFS(avg-values, test-values, condition, test-values…, condition…)
 avg-values: A collection containing the values to be averaged. avg-values is a
reference to a single range of cells or an array, which may contain only numbers,
numeric expressions, or Boolean values.
 test-values: A collection containing values to be tested. test-values is a collection
containing any type of value.
 condition: An expression that results in a logical TRUE or FALSE. condition is an
expression that can contain anything as long as the result from comparing condition
to a value in test-values can be expressed as a Boolean value of TRUE or FALSE.
 test-values…: Optionally include one or more additional collections containing
values to be tested. Each test-values collection must be followed immediately with a
condition expression. This pattern of test-values, condition can be repeated as many
times as needed.
 condition…: If an optional collection of test-values is included, an expression that
results in a logical TRUE or FALSE. There must be one condition following each
test-values collection; therefore, this function will always have an odd number of
arguments.
