Answer:
0°C
No Modal
Step-by-step explanation:
The range of a set is calculated by subtracting the max value by the lowest value in the set. Which using the data provided would be the following
range Last Year: 19 - 9 = 10
range 2 years ago: 17 - 7 = 10
Since we see that the range for both sets is 10 degrees then the difference is 0 degrees.
There is no modal temperature last year since no same temperature has appeared more than once.
