Brock scored the following number of goals in her soccer games: 2, 3, 1, 0, 3, 2,1, 2. What is the mean of the data?

Answer 1

#1.75#

The equation that you require is

#color(blue)("mean" = (sum("values"))/"number of values")#

In this instance, the values stand for the goals scored and the numbers for the matches played.

Notice that Brock played a total of #8# football games, but that he only scored in #7# of those matches. However, you still need to take into account the value #0# and count it for the total number of matches.

Enter your values to discover

#"mean" = (2 + 3 + 1 + 0 + 3 + 2 + 1 + 2)/8#

#"mean" = 14/8 = color(green)("1.75")#
