Upper Quartile Formula For Ungrouped Data. Quartiles for ungrouped data. Since the data given in the problem is ungrouped therefore following formula will be used for the calculation of second quartile.
Q 3 i 3 n 1 4 th value of observations where i 1 2 3. The formula for ith quartile is. Here the average needs to be taken which is of 2 nd and 3 rd terms which are 45 and 50 and the average formula of same is 45 50 2 47 50.
Here q1 is first quartile q2 is second quartile and q3 is third quartile.
Here the average needs to be taken which is of 2 nd and 3 rd terms which are 45 and 50 and the average formula of same is 45 50 2 47 50. Q 3 i 3 n 1 4 th value of observations where i 1 2 3. N 1 3 4 th term is the upper quartile. Calculation of quartile q1 can be done as follows q1 n 1 th term.
