2015 AMC 8 Problems/Problem 5

Billy's basketball team scored the following points over the course of the first 11 games of the season: $42, 47, 53, 53, 58, 58, 58, 61, 64, 65, 73$ If his team scores 40 in the 12th game, which of the following statistics will show an increase?

$\textbf{(A) } \text{range} \qquad \textbf{(B) } \text{median} \qquad \textbf{(C) } \text{mean} \qquad \textbf{(D) } \text{mode} \qquad \textbf{(E) } \text{mid-range}$

When they score $40$ , the range increases from $73-42=31$ to $73-40=33$ . This means the $\boxed{\textbf{(A) } \text{range}}$ increased.
