# funció MITJANASICONJUNT

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.

Aquesta funció és disponible des de la versió 4.0 del LibreOffice.

### Sintaxi

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: A criterion is a text expression computed from a single cell Reference, Formula, Number or Text. It is used in comparisons with cell contents.

A reference to an empty cell is interpreted as the numeric value 0.

A matching expression can be:

- A number or logical value. A matching cell content equals the number or logical value.

- A value beginning with a comparator (<, <=, =, >, >=, <>).

  For =, if the value is empty it matches empty cells.

  For <>, if the value is empty it matches non-empty cells.

  For <>, if the value is not empty it matches any cell content except the value, including empty cells.

  Note: "=0" does not match empty cells.

  For = and <>, if the value is not empty and can not be interpreted as a number type or one of its subtypes and the property Search criteria = and <> must apply to whole cells is checked, comparison is against the entire cell contents, if unchecked, comparison is against any subpart of the field that matches the criteria. For = and <>, if the value is not empty and can not be interpreted as a Number type or one of its subtypes applies.

- Other Text value. If the property Search criteria = and <> must apply to whole cells is true, the comparison is against the entire cell contents, if false, comparison is against any subpart of the field that matches the criteria. 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 Criterion.

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 regular expression metacharacter or operator 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 LibreOffice - Preferences Tools - Options - LibreOffice Calc - Calculate.

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).

### Exemples

Considereu la taula següent

| A | B | C
1 | Nom del producte | Sales | Revenue
2 | llapis | 20 | 65
3 | ploma | 35 | 85
4 | quadern | 20 | 190
5 | llibre | 17 | 180
6 | estoig | not | not

En tots els exemples següents, els intervals del càlcul contenen la fila 6, la qual és ignorada perquè conté text.

#### Ús simple

=MITJANA(A1:A50)

Calcula la suma de valors de l'interval B2:B6 majors o igual a 20. Retorna 75, perquè la cinquena fila no compleixen el criteri.

=MITJANA(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.

#### Ús d'expressions regulars i funcions imbricades

=COMPTASICONJUNT(B2:B6;">"&MIN(B2:B6);B2:B6;"<"&MAX(B2:B6))

Calcula la suma de valors de l'interval C2:C6 que corresponen a tots els valors de l'interval B2:B6 excepte el mínim i el màxim. Retorna 255, perquè la tercera i la cinquena files no compleixen almenys un criteri.

=MITJANASICONJUNT(C2:C6;A2:A6;E2&".*";B2:B6;"<"&MAX(B2:B6))

Calcula la suma de valors de l'interval C2:C6 que corresponen a totes les cel·les de l'interval A2:A6 començant per "llapis" i a totes les cel·les de l'interval B2:B6 excepte el màxim. Retorna 65, perquè només la segona fila compleix tots els criteris.

#### Referència a una cel·la com a criteri

Si heu de canviar el criteri fàcilment, potser voleu indicar-lo en una cel·la separada i usar una referència a aquesta cel·la en la condició de la funció MITJANASICONJUNT. Per exemple, la funció superior es pot reescriure com a:

=MITJANASICONJUNT(C2:C6;A2:A6;E2&".*";B2:B6;"<"&MAX(B2:B6))

Si E2 = llapis, la funció retorna 65, perquè l'enllaç a la cel·la se substitueix amb el seu contingut.
