AVERAGEIFS function
Returns the arithmetic mean of all cells in a range that satisfy given multiple criteria. The AVERAGEIFS function sums up all the results that match the logical tests and divides this sum by the quantity of selected values.

AVERAGEIFS(Func_Range; Range1; Criterion1[; Range2; Criterion2][; … ; [Range127; Criterion127]])
Func_range – required argument. It is a range of cells, a name of a named range or a label of a column or a row containing values for calculating the mean.
Range1 – required argument. It is a range of cells, a name of a named range, or a label of a column or a row, to which the corresponding criterion is to be applied.
Criterion1 – required argument. A string expression representing a logical condition or a cell reference to such string expression. The expression can contain text, numbers, regular expressions or wildcards (if enabled in calculation options).
Range2 – Optional. Range2 and all the following mean the same as Range1.
Criterion2 – Optional. Criterion2 and all the following mean the same as Criterion1.
The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every character with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in .
When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".
Func_Range and Range1, Range2... must have the same size, otherwise the function returns err:502  Invalid argument.
The logical relation between criteria can be defined as logical AND (conjunction). In other words, if and only if all given criteria are met, a value from the corresponding cell of the given Func_Range is taken into calculation.
The function can have up to 255 arguments, meaning that you can specify 127 criteria ranges and criteria for them.
If a cell contains TRUE, it is treated as 1, if a cell contains FALSE – as 0 (zero).

Simple usage
=AVERAGEIFS(B2:B6;B2:B6;">=20")
Calculates the average for values of the range B2:B6 that are greater than or equal to 20. Returns 25, because the fifth row does not meet the criterion.
=AVERAGEIFS(C2:C6;B2:B6;">=20";C2:C6;">70")
Calculates the average for values of the range C2:C6 that are greater than 70 and correspond to cells of B2:B6 with values greater than or equal to 20. Returns 137.5, because the second and fifth rows do not meet at least one criterion.
Using regular expressions and nested functions
=AVERAGEIFS(C2:C6;B2:B6;">"&MIN(B2:B6);B2:B6;"<"&MAX(B2:B6))
Calculates the average for values of the range C2:C6 that correspond to all values of the range B2:B6 except its minimum and maximum. Returns 127.5, because the third and fifth rows do not meet at least one criterion.
=AVERAGEIFS(C2:C6;A2:A6;"pen.*";B2:B6;"<"&MAX(B2:B6))
Calculates the average for values of the range C2:C6 that correspond to all cells of the A2:A6 range starting with "pen" and to all cells of the B2:B6 range except its maximum. Returns 65, because only second row meets all criteria.
Reference to a cell as a criterion
If you need to change a criterion easily, you may want to specify it in a separate cell and use a reference to this cell in the condition of AVERAGEIFS function. For example, the above function can be rewritten as follows:
=AVERAGEIFS(C2:C6;A2:A6;E2&".*";B2:B6;"<"&MAX(B2:B6))
If E2 = pen, the function returns 65, because the link to the cell is substituted with its content.
