Mr. finch has 8 plants in his backyard. these are 12.9, 8.3, 5.7, 10.6, 7.4, 9.8, 1.5 and 12.5 feet tall. what is the 25th percentile

The 25% percentile comes between the numbers 5.7 and 7.4. As a result, we take the average and the answer is 6.55.

In order to find where the percentiles fall, you need to line them all up and then draw a line after 1/4th of the numbers. In this case, there is 8 numbers, so we draw the line after the second lowest.
