# How to Calculate Quintiles in Excel (With Examples)

In statistics, quintiles are numbers that split a dataset into five groups of equal frequency.

The first quintile is the point where 20% of all data values lie below it. The second quintile is the point where 40% of all data values lie below it, and so forth.

We can use the following function to calculate the quintiles for a dataset in Excel:

```=PERCENTILE(CELL RANGE, QUINTILE)
```

The following example shows how to use this function in practice.

### Example: Calculate Quintiles in Excel

Suppose we have the following dataset with 20 values: The following image shows how to calculate the quintiles for the dataset: The way to interpret the quintiles is as follows:

• 20% of all data values lie below 6.8.
• 40% of all data values lie below 14.
• 60% of all data values lie below 20.8.
• 80% of all data values lie below 26.2.

We can also use the following formula to calculate each quintile at the same time:

```=PERCENTILE(CELL RANGE, {0.2, 0.4, 0.6, 0.8})
```

The following image shows how to do so: Notice that the quintiles calculated here match the quintiles we calculated earlier.
