=PERCENTILE.INC(array, k)

#### Arguments

• array (required): The array or range of data according to which to calculate the k-th percentile.
• k (required): The percentile value or a decimal value in the range from 0 to 1, including 0 and 1. For example, k=0.9 means to the 90th percentile of the values in array, meaning that 90% of values are less than or equal to the calculated result.

#### Function Notes

• PERCENTILE.INC returns the #VALUE! error value if k is not numeric.
• PERCENTILE.INC returns the #NUM! error value if:
• k < 0 or k > 1;
• array is empty.
• If the requested quartile falls between two of the values in the array, PERCENTILE.INC will interpolate and return an intermediate value.

#### Example

To get the 90th, 70th, 50th percentiles of the array as shown below, please copy or enter the formula below in the top cell F5, and press Enter to get the first result:

=PERCENTILE.INC(\$B\$3:\$B\$11,E5)

√ Note: The dollar signs (\$) above indicate absolute references, which means the array argument in the formula won't change when you move or copy the formula to other cells. However, there are no dollar signs added to k since you want it to be dynamic. After entering the formula, drag the fill handle down to apply the formula to the below cells. #### PERCENTILE.INC VS. PERCENTILE.EXC

• PERCENTILE.EXC excludes percentages from 0 to 1/(n+1) and from n/(n+1) to 1 as k values, the n in which is the number of elements in array.
