Question

Elena, Jada, and Lin enjoy playing basketball during recess. Lately, they have been practicing free throws. They record the number of baskets they make out of 10 attempts. Here are their data sets for 12 school days.

Elena: 4 5 1 6 9 7 2 8 3 3 5 7


Jada: 2 4 5 4 6 6 4 7 3 4 8 7


Lin: 3 6 6 4 5 5 3 5 4 6 6 7


Calculate the mean number of baskets each player made, and compare the means. What do you notice?

Answer 1

They all have the same mean of 5

Explanation:

first add up all the numbers in each data set separately and then divide by the total number (12) to find the mean for example

Elena: 4+5+1+6+9+7+2+8+8+3+3+5+7= 60

60 divided by 12 equals 5

all three have the same mean of 5
