# Statistical Functions Part Four

## AVERAGEIF

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

## AVERAGEIFS

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.

## PERCENTRANK.EXC

Returns the relative position, between 0 and 1 (exclusive), of a specified value within a supplied array.

The difference between PERCENTRANK.INC and PERCENTRANK.EXC is that PERCENTRANK.INC calculates a value in the range 0 to 1 inclusive, whereas the PERCENTRANK.EXC function calculates a value in the range 0 to 1 exclusive.

PERCENTRANK.EXC(Data; Value [; Significance])

Data represents the array of data in the sample.

Value represents the value whose percentile rank must be determined.

Significance An optional argument that specifies the number of significant digits that the returned percentage value is rounded to.

=PERCENTRANK.EXC(A1:A50;50) returns the percentage rank of the value 50 from the total range of all values found in A1:A50. If 50 falls outside the total range, an error message will appear.

## QUARTILE.EXC

Returns a requested quartile of a supplied range of values, based on a percentile range of 0 to 1 exclusive.

The difference between QUARTILE.INC and QUARTILE.EXC is that the QUARTILE.INC function bases its calculation on a percentile range of 0 to 1 inclusive, whereas the QUARTILE.EXC function bases its calculation on a percentile range of 0 to 1 exclusive.

QUARTILE.EXC(Data; Type)

Data represents the range of data values for which you want to calculate the specified quartile.

Type An integer between 1 and 3, representing the required quartile. (if type = 1 or 3, the supplied array must contain more than 2 values)

=QUARTILE.EXC(A1:A50;2) returns the value of which 50% of the scale corresponds to the lowest to highest values in the range A1:A50.

## MODE.MULT

Returns a vertical array of the statistical modes (the most frequently occurring values) within a list of supplied numbers.

MODE.MULT(Number 1 [; Number 2 [; … [; Number 255]]])

As the MODE.MULT function returns an array of values, it must be entered as an array formula. If the function is not entered as an array formula, only the first mode is returned, which is the same as using the MODE.SNGL function.

=MODE.MULT(A1:A50)

## PERCENTILE.EXC

Returns the Alpha'th percentile of a supplied range of values for a given value of Alpha, within the range 0 to 1 (exclusive). A percentile returns the scale value for a data series which goes from the smallest (Alpha=0) to the largest value (Alpha=1) of a data series. For Alpha = 25%, the percentile means the first quartile; Alpha = 50% is the MEDIAN.

If Alpha is not a multiple of 1/(n+1), (where n is the number of values in the supplied array), the function interpolates between the values in the supplied array, to calculate the percentile value. However, if Alpha is less than 1/(n+1) or Alpha is greater than n/(n+1), the function is unable to interpolate, and so returns an error.

The difference between PERCENTILE.INC and PERCENTILE.EXC is that, in the PERCENTILE.INC function the value of alpha is within the range 0 to 1 inclusive, and in the PERCENTILE.EXC function, the value of alpha is within the range 0 to 1 exclusive.

PERCENTILE.EXC(Data; Alpha)

Data represents the array of data.

Alpha represents the percentage of the scale between 0 and 1.

## PEARSON

Returns the Pearson product moment correlation coefficient r.

=POISSON(60;50;1) returns 0.93.

## POISSON.DIST

Returns the Poisson distribution.

POISSON.DIST(Number; Mean [; C])

Number represents the value based on which the Poisson distribution is calculated.

## PERCENTILE

Returns the alpha-percentile of data values in an array. A percentile returns the scale value for a data series which goes from the smallest (Alpha=0) to the largest value (alpha=1) of a data series. For Alpha = 25%, the percentile means the first quartile; Alpha = 50% is the MEDIAN.

PERCENTILE(Data; Alpha)

Data represents the array of data.

Alpha represents the percentage of the scale between 0 and 1.

=PERCENTILE(A1:A50;0.1) represents the value in the data set, which equals 10% of the total data scale in A1:A50.

## PERCENTILE.INC

Returns the alpha-percentile of data values in an array. A percentile returns the scale value for a data series which goes from the smallest (Alpha=0) to the largest value (alpha=1) of a data series. For Alpha = 25%, the percentile means the first quartile; Alpha = 50% is the MEDIAN.

The difference between PERCENTILE.INC and PERCENTILE.EXC is that, in the PERCENTILE.INC function the value of alpha is within the range 0 to 1 inclusive, and in the PERCENTILE.EXC function, the value of alpha is within the range 0 to 1 exclusive.

PERCENTILE.INC(Data; Alpha)

Data represents the array of data.

Alpha represents the percentage of the scale between 0 and 1.
