So we want to find the interquartile range or the iqr of this following data set.
00:07
So here's how we're going to do it.
00:08
The first step to finding the iqr is to knowing that to find the iqr, you need to do q3 minus q1.
00:14
Now, let's find what those values are first.
00:16
So the first step is to find the median of this data set.
00:19
So if we take values out from the top and the bottom, we will settle upon 47 being the median.
00:24
Now, we don't exactly need to know the exact value, but we just need to know where the median is.
00:29
So i'm going to mark this with m for median.
00:31
Now we can split the data set into a lower half and an upper half.
00:34
So now the median of the lower half is going to be q1, and the median of the upper half is going to be known as q3...
