- data_array - An array of values for which you want to get frequencies.
- bins_array - An array of intervals ("bins") for grouping values.
The FREQUENCY function counts how often numeric values occur in a set of data and returns a frequency distribution – a list that shows the frequency (count) of each value in a range at given intervals (bins). FREQUENCY returns the distribution as a vertical array of numbers that represent a "count per bin".
The FREQUENCY function always returns an array with one more item than bins in the bins_array. This is by design, to catch any values greater than the largest value in the bins_array. The general pattern for FREQUENCY is:
where data_array and bins_array are typically ranges on the worksheet.
To create a frequency distribution using FREQUENCY:
- Enter numbers that represent the bins you want to group values into
- Make a selection the same size as the range that contains bins, or one greater if want to include the extra item
- Enter the FREQUENCY function as a multi-cell array formula with control+shift+enter.
In Excel 365, it is not necessary to enter FREQUENCY as an array formula. See notes below.
In the example shown, the formula in G5:G8 is:
Entered as a multi-cell array formula.
Note: the curly braces added by Excel automatically when entered with control + shift + enter.
FREQUENCY will return an array of six counts, and these counts will spill automatically into the range G5:G9. The count in the last row (G9) is the overflow bin, the count of any values greater than the largest value in the bins_array.
- FREQUENCY returns multiple values and must be entered as an array formula, except in Excel 365.
- FREQUENCY always returns an array with one more item than bins. This is by design, to catch any values greater than the largest interval in the bins_array.
- Each bin shows a count of values up to and including bin value, excluding values already accounted for.
