Locate the units as described in the following data table:

- Determine the position of the 1st percentile. In the cell to calculate enter the formula : = QUARTILE.INC (D6: J6, D7)

- Press Enter -> 1st percentile is:

- The fourth percentile. In the cell to calculate enter the formula: = QUARTILE.INC (D6: J6, D8). Press Enter -> return value is:

- In case the value of quart = 0 -> the function still calculates normally.

- Where the quart value = 6> 4 -> the function returns the #NUM! Error value
