In a soccer competition in one season, a club had scored the following goals: 2, 0, 3, 3, 2, 1, 4, 0, 0, 5, 1, 0, 2, 2, 1, 3, 1, 4, 1 and 1. The mean, median and mode are respectively
 

  • A 1, 1.8 and 1.5
  • B 1.8, 1.5 and 1
  • C 1.8, 1 and 1.5
  • D 1.51, 1 and 1.8

The correct answer is B. 1.8, 1.5 and 1

By re-arranging the goals in ascending order 0. 0. 0. 0. 0, 1. 1. 1. 1. 1. 1, 2, 2, 2, 2, 3, 3, 3, 4, 4, 5.
Mean = \(\frac{36}{20}\) = 1.8
Median = \(\frac{1 + 2}{2}\)
= \(\frac{3}{2}\)
= 1.5
Mode = 1
= 1.8, 1.5 and 1
