In this problem, we are given a sample that includes a list of scores and the values that we have are 12, 2, 9, 13, 4, 11, followed by 2, 10, 6, 8, then we have 1, 14, 5, 15 and 8.
00:20
And we have to get the interquotile range of this sample.
00:24
So we will represent that with iqr, and that's what we have to get.
00:27
So first let's arrange the values in the sample in increasing order.
00:32
So doing that we get 1 followed by 2 appearing twice, then we have 4, 5, 6, followed by 8 appearing 2 times, then we have 9, 10, 11, 12 followed by 13, 14 and 15.
00:47
And we see that it's this data value 8 which is at the center of this arranged dataset...
