frequency() Function

## Function

frequency( data_array, bins_array )

Uses the bin array to create groups bounded by the elements of the array.

## Parameters

Keyword Type Description

`data\_array`

Decimal Array

The set of numbers that will be divided into groups according to bins_array and then counted

`bins\_array`

Decimal Array

The upper (and inclusive) boundaries of the groups into which the elements from the data array will be dispersed.

Integer Array

## Usage considerations

### Using the bins_array parameter

The bins_array argument also defines one additional group capturing all numbers greater than the maximum number in bins_array.

### Understanding results

The return value represents how many elements from the data array fall into each of these groups.

## Examples

You can experiment with this function in the test box below.

Test Input

For example, a bin array equal to `{70, 79, 89}` defines four groups:

• numbers where number <= 70
• numbers where 70 < number <= 79
• numbers where 79 < number <=89
• numbers > 89

`frequency({64,74,75,84,85,86,95},{70,79,89})` returns `1*2*3*1`
