# PercentileDisc

The **PercentileDisc** function calculates the discrete kth percentile value for a column or group. It returns the percent of the total frequency under that number, demonstrating the relative position of the value compared to the entire set of data. 

### Syntax

`PercentileDisc(column, k)`

The function has the following arguments:

|            |                                                                                                                 |
| ---------- | --------------------------------------------------------------------------------------------------------------- |
| **column** | (required) The column to search.                                                                                |
| k          | (required) A number between `0` and `1`, which corresponds to the percent of data below that number.`0 < k < 1` |

### Example

A *Score* column contains values 2, 4, 6, 8, and 10.

```
PercentileDisc([Score], 0.7)
```

* The discrete 70th percentile of the *Score* column is 8. If a candidate scores in the 70th percentile, they have scored higher than 70% of test takers, putting them in the top 30%
