Question

What is the median and mode for the following list of values? 

13, 18, 13, 14, 13, 16, 14, 21, 13 

(a) 14 and 13 

(b) 15 and 16 

(c) 14 and 15 

(d) 13 and 16 

Answer 1

Correct option a. (14 and 13)

Explanation:

• The median is the middle value, so to rewrite the list in order: 13, 13, 13, 13, 14, 14, 16, 18, 21

• There are nine numbers in the list, so the middle one will be (9 + 1)/2 =5 = 5th number, So the median is 14.

• The mode is the number that is repeated more often than any other, so 13 is the mode.
