The daily low temperatures during one week were reordered as follows: 2 degrees F, -7 degrees F, 6 degrees F, -3 degrees F, -14 degrees F, -16 degrees F, and -10 degrees F. Explain how you would show a child how to find the average daily low temperature for week.

Answer 1

It's the same as finding the average of any set of numbers.

Add up the values and divide by how many there are.

(2 + -7 + 6 + -3 + -14 + -16+ -10)/7 = -42/7 = -6

The child had better be familiar with the concept of negative values, as well as division.
