The upper 70th percentile is the number below which 70% of the data lie.
The 70th percentile position is given by:
Thus, the 70th percentile position is approximately the 25th data item (after the data has been arranged in acsending order).
Given the following data:
<span>16 24 25 26 27 29 36 39 39 39 40 44 45 47 47 48 50 51 51 53 53 54 57 58
58 60 65 66 67 69 69 71 72 74 74 74
The 25th data in the data set is 58.
Therefore, the upper P70 is 58.
