In this problem we are given the data set and that includes the values and they are 64 followed by 76 appearing twice, then we have 67, 66, then we have 72, 61, then we have 58, 77 and 79.
00:22
And we have to determine its interquotile range and we have represented that with iqr.
00:28
So that's what we have to get.
00:30
So first let's arrange the values in the data set in increasing order.
00:34
So doing that we get 58, 62, 64, followed by 66, then we have 67, 71, 72, 72, 76 appearing twice, then we have 77 and 79.
00:49
And we have the data value 71, which is at the center of this arranged dataset.
00:54
So if we look upon the median at the first half, well that's 64...
