Question

Given the following dataset, what is the 71st percentile of the data? Round to the nearest whole number. 272 232 • 219 155 332 192 155 169 188

Answer 1

Solution:

We have to first sort the data in ascending order as:

The 71st percentile of the data is:

$P_{71}=(0.71 \times n)^{th }item$

$=(0.71 \times 15)^{th }item$

$=(10.65)^{th }item\approx 11^{th }item$

$=264$
