# Median

## Description

This operation calculates the median value of a set of numbers separated by a specified delimiter. The median is a statistical measure representing the middle value of a sorted dataset. It divides the data into two halves, with 50% of the data points below and 50% above the median.

## Data types

These are the input/output expected data types for this operation:

### Input data

### Output data

## Parameters

These are the parameters you need to configure to use this operation (mandatory parameters are marked with a <mark style="color:red;">**\***</mark>):

<details>

<summary>Delimiter<mark style="color:red;"><strong>*</strong></mark></summary>

Choose the delimiter that separates the numbers in your input data:

* **Line feed** - Select this to have each line of text as a separate value.
* **Space** - Your numbers are separated by spaces.
* **Comma** - Your numbers are separated by commas (`,`)
* **Semi-colon** - Your numbers are separated by semi-colons (`;`)
* **Colon** - Your numbers are separated by colons (`:`)
* **CRLF** - Carriage return line feed (CRLF) is a control character that originally referred to moving the carriage on typewriters back to the starting position. In computing, it’s used in classic Mac OS and some Windows-based systems to mark the end of a line. If your input uses `\r` as the line-ending character, you can set the delimiter to `\r` to correctly separate values. For example: `100\r200\r300`

## Example

Suppose you want to calculate the **median** a series of numbers in your input strings. They are separated by commas (,). To do it:

1. In your Pipeline, open the required [Action](https://docs.onum.com/the-workspace/pipelines/actions) configuration and select the input **Field**.
2. In the **Operation** field, choose **Median**.
3. Set **Delimiter** to **Comma**.
4. Give your **Output field** a name and click **Save**. You'll get the median of the numbers in your input data. For example:

```
10, 5, 20, 15, 25 -> 15
```
