Question

Lena is recording the number of points she misses on each math quiz. Here are her results for the last nine quizzes.

Answer 1

Answer:

The range of the data is the difference between the largest and smallest value. In this case, the largest value is 8 and the smallest value is 1.

Hence, the range is $8-7=1$.

---------------------------------------------

The mode is the value that appears in a data set the most. When you arrange them in ascending order:

$1, 4, 6, 6, 6, 6, 6, 8, 8$

You can count that the value "6" appears five times, which is the most in this set.

Hence, the mode is 6.

Answer 2

The mode is 6 because it’s the one you see the most
and the range is 7 because it’s the difference between the highest number which is 8 and the lowest number which is 1
