All right, we're given a bunch of data points and asked to find the percentile of a given value.
00:06
So the data points are 122, 134, 126, 120, 120, 128, 112, 128, 130, 120, 128, then 125, 122, 126, 136, 118, 118, 122, and 222, 122, 124, and finally, 119.
00:46
So the data value that we're looking for is 128.
00:52
So that's the question of what percentile is at in this data set.
00:55
So the first thing to do is to put these in order.
00:58
It doesn't matter if you put it from lowest to highest or highest lowest, but might as well go in descending order.
01:04
Might as well.
01:04
It doesn't matter.
01:06
So we go 136 is our largest number.
01:10
Then 10034, 130, 123, 128, 128, 126, twice.
01:20
So 126, write it down two times...
