Cold Integers

North Math ONLY -
This blog assignment is due no later than January 28th!

Ms. Saarinen’s dad has always been a hockey fan and has decided to take the family to go visit the Hockey Hall of Fame in Toronto, Canada. Ms. Saarinen wasn’t sure she wanted to make the trip because as you know, she doesn’t like the cold weather. Ms. Saarinen asked her math students to help her find the average temperature in Toronto to help her prepare for the trip.


The average daily temperatures (in Fahrenheit) in Toronto for the previous two weeks are:



+6, -1, 0, -2, +4, -1, -1, -9, -6, -9, -12, -2, 0, and +3.


1. What is the range of the data?


2. What is the median temperature?


3. What is the mean temperature?


4. What is the mode temperature?


5. How would the mean change if the next day’s temperature of +7 was included in the data?


6. Suppose Ms. Saarinen was told that the average temperature in Toronto for one week in December was -2 degree Fahrenheit. She could read the temperatures for six of the temperatures on the newspaper, but the last temperature was smudged by someone’s greasy fingers. The six temperatures she could read were -7, +3, -5, 0, +4, and -1. What is the missing temperature?
