In this question we are given some values.
00:03
I'll write the values here.
00:05
46, 47, 49, 49, 51, 53, 54, 54, 55 and 59.
00:18
55 and 59.
00:19
So totally we have 11 values.
00:22
So, n equal to 11.
00:23
So we have to find here the median, the first model, that is median m.
00:28
Quartile first quartile q1 and the third quartile q3 so first we have to arrange the numbers in ascending or descending order the given numbers are in ascending order so we will directly find the median so median m equal to value at n plus 1 by second tooth item okay so which means that value at 11 plus 1 by 2 11 plus 1 by truth item so which is equal to value at 6th item so what is the value we have at 6th position 1 2 3 4 5 6 okay therefore this is the median so which is equal to 53 medium equal to 3 okay next we have to find the quartile first quartile similarly q1 quartile means we are dividing the given into four equal parts okay so therefore value at n plus 1 by fourth item okay so this is the formula to find the quartile so which is equal to value at n plus 1 means 11 plus 1 by 4 which is equal to 12 by 4 right i'll write in a single step 12 by 4 which is equal to 3 okay so third item so what is the value at third item? the third position value is 49.
01:52
Therefore q1 is 49.
01:55
Okay.
01:55
So this one, first part of the q1 is 49, which is equal to 49.
02:00
Next to q3.
02:02
So which is equal to value at three times n plus 1 by fourth item...
