Hello, let's have a look on the question.
00:02
So this is the data given to us.
00:04
Since this is already arranged in ascending order, so we can find out median, or we can say q2, that is second quartile is median.
00:15
So this will be equal to, since these are the two middle terms, so we can find out the mean of these terms, that is 188 plus 190 divided by 2, which is equal to 189.
00:26
So 189 here is the median.
00:29
The first quartile, first quartile represented by q1 is equal to 175.
00:38
Then we have third quartile, third quadile, that is, q3 is equal to 204.
00:48
Now we need to find out the interquotile range.
00:52
So interquotile ranges, this is equal to represented by iqr, this is equal to 204, that that is q3 minus q1 175...
