Question

Find the 1st , 2nd (median) and 3rd quartile of the set of numbers 6,8,2,6,7,9 ?

Answer 1

Median Q2 = 6.5

First Quartile = 6

Third Quartile = 8

Explanation:

First Quartile Q1 = 6

Second Quartile Q2 = 6.5

Third Quartile Q3 = 8

Interquartile Range IQR = 2

Median = Q2 x˜ = 6.5

Minimum Min = 2

Maximum Max = 9

Range R = 7

Answer 2

at first we put the numbers in order from least to greatest

2 , 6 , 6 , 7 , 8 , 9

1st quartile = 6

median = (6+7)/2 = 6.5

3rd quartile = 8
