# Five Great Excel Statistical Functions

Microsoft Excel statistical functions provide the ability to analyse and summarise the data in a spreadsheet. There are many statistical functions in Excel and they seem to grow in almost every new version release of the software.

This article looks at five great Excel statistical functions and how they could be used.## RANK

The RANK function returns the ranking position of a value with a range.

The function syntax is shown below;

=RANK(number, ref, [order])

**Number:** The
number whose rank you want to return.

**Ref:** The cell
range containing the list of numbers you want to check.

**Order:** The order
in which to perform the ranking. 0 for a descending order (largest to
smallest), and 1 for ascending (smallest to largest). If this argument is
omitted then 0 is used.

The example below shows the RANK function returning the rank 2 for the number 8 in the list.

=RANK(A3, A2:A5, 0)

## LARGE

The LARGE function returns a value that meets a specified
ranking position within a range of values. For example, the LARGE function
could return the 3^{rd} largest value from a list.

The function looks like this;

=LARGE(array, k)

**Array:** The range
of cells that make up the list you want to check.

**K:** The ranking
position within the array, from the largest, that you want to return.

The example below returns the number 5 as the 3^{rd}
largest number in the list.

## AVERAGEIF

The AVERAGEIF function was a new edition to the release of Excel 2007. It is used to calculate the average of values in a range based on specific criteria e.g. find the average sales value for those taken by a salesperson called John.

The function is written as below;

=AVERAGEIF(range, criteria, [average_range])

**Range**: The range
of cells that you want to evaluate.

**Criteria**: The
logical test that has to be met for the values to be included.

**Average_range**:
The range of cells that include the values you want to average.

In the example below the cell range A1:B10 contains sales figures with the names of the salesperson in column A, and the order total in column B. The formula below would return the average value for sales made by John.

=AVERAGEIF(A1:B10, “John”, B1:B10)

## COUNTBLANK

The COUNTBLANK function returns the number of empty cells with a range.

It looks like the below;

=COUNTBLANK(range)

**Range:** The range
of cells that you want to count.

The COUNTBLANK function below is shown returning 4 blank cells from the range.

## COUNTA

The Excel COUNTA function counts the number of non-empty cells within a range. COUNTA counts numbers, text and formulas.

It looks like the below;

=COUNTA(value1, [value2], …)

**Value:**The range
of cells that you want to count.

The example below shows the function counting the non-empty cells within a range.
