What is the third quartile of this data set? 14, 18, 20, 21, 25, 32, 42, 46, 48 a. 32 b. 42 c. 44 d. 43

Answer with Step-by-step explanation:

When number of terms are odd the quartiles are the terms

Here we have to calculate the third quartile i.e. i=3

and number of terms are 9

i.e. n=9

Q3=7.5 th term

7 th term=42

8 th term=46

7.5 th term is the mean of 7 th and 8 th term

= (42+46)/2

= 44

Hence, Correct option is:

C. 44
