In this question on arranging the given set in ascending order we get 3, 4, 6, 8, 15, 15 and 8.
00:12
So first to calculate the first quartile we can calculate the first quartile.
00:21
So the first quartile will be one by fourth of the n plus one term.
00:28
The first quartile will be one by fourth of the n plus one term.
00:32
So here we have total of seven terms.
00:35
So n value will be equal to seven one by fourth of seven plus one the term will be the first quartile.
00:43
So on simplifying this we get one by four times of eight which is equal to so this is equal to the second term.
00:52
So the second term is the first quartile.
00:54
So let's denote it as q1.
00:56
So q1 is equal to the second term which is four.
01:00
So this is the first quartile...
