Upper Quartile Formula. 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. The middle term between the median and first term is known as the first or lower quartile and is written as q1.
The formula for the upper quartile is given as. So firstly we put your numbers in order. Similarly the value of mid term that lies between the last term and the median is known as the third or upper quartile and is denoted as q3.
Q3 n 1 th term.
However the value will not be for third quarter bit term number would be q3. The q1 is 47 50 which is bottom 25. The upper quartile formula is. So upper quartile q3 11.
