## Hàm SECOND

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.

### Cú pháp

AVERAGEIFS(Func_Range; Range1; Criterion1 [ ; Range2; Criterion2 [;...]]))

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.

#### Simple usage

=AVERAGE(A1:A50)

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.

=AVERAGE(A1:A50)

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.
