Let me just write these numbers orderly.
00:02
So we got 15, 18, 19, 23, 23, 26, 27, 28, 29 and 50.
00:17
So there are total 10 numbers we got here.
00:21
Okay, so first one, let's start with the median score.
00:27
So median also called as q2.
00:29
So we have to find the middle score.
00:32
There are 10 numbers here.
00:33
So 10 plus 1 over 2 term, which is 5 .5th term.
00:41
That would be the fifth term plus the sixth term divided by 2.
00:46
This is 1, 2, 3, 4, 5, 6.
00:50
So that would be 23 plus 26 divided by 2, which is equal to 24 .5.
00:57
So we got the q2 value as 24 .5.
01:01
What about the q1? so the q1 is the lower quartile.
01:06
So let me just draw the median score.
01:09
This is the median score.
01:11
So before median score, how many numbers do we have? we have five numbers here.
01:16
So the middle score is 19...
