Hey there! :)

Your answer is mean
_____________________________________________________________

Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.

Finding the mode is pretty useless because you can't do much with the score that you got the most.

Range isn't that helpful because it's the difference between your best and worst score.

Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________

Therefore, the answer is mean

Hope this helps :)
