*************
(15+1)/2 = 8
So, 8th term is our median. From cummulative frequency we can see 8th term has the value of 10.
Therefore, Median: 10
**************
Q1 = (n+1)/4 th term
(15+1)/4 = 16/4 = 4th position
So, Q1 = 8, Since 4th position in our table has value of 8
******************
Q3 postion = Q1 position + median position = 8+4 =12
So, 12 term is our Q3,
Q3: 11, Since 12 term has value 11.
TLDR;
Min: 7
Q1: 8
Median: 10
Q3: 11
Max: 14
