Question

During a 12 hour period, the temperature in a city dropped from a high 69 degrees F to a low -26 degrees F. What was the range during this period?

Answer 1

The range of a dataset is the difference between the highest value in the data and the lowest value.

We know the highest value of the temperature in a city was 69°F and the lowest was -26°F.

The range is the difference of these values:

Range = 69°F - (-26°F)

The subtraction becomes a sum because of the product of two minus signs:

Range = 69°F + 26°F = 95°F
