Sagot :

Answer:

1st quartile of the data set = 7

Step-by-step explanation:

Given data set,

1, 5, 7, 9, 11, 16, 18, 20, 30, 35

Median of the given data set is called as "second quartile"

Median of the given set = Average of the terms at the center (Since, the number of data set is even)

                                        = [tex]\frac{1}{2}(11+16)[/tex]

                                        = 13.5

Number of terms on the left of 13.5 = 5

Term at the center (median) of (1, 5, 7, 9, 11) = 7

Therefore, 1st quartile of the data set = 7
