Answer:
To find:
1. Range of temperature between two years
2. Modal temperature last year
3. Median temperature 2 years ago.
Solution:
1. Range is difference between the highest and lowest value.
Range of last year = highest value-lowest value
= 27-6 = 23
Range 2 years ago = highest value - lowest value
= 25-17 = 18
So, difference in range of temperature between two years = 23-18 = 5
2. Modal temperature last year = 11°C
(number that appears most frequently in the series arranged in numerical
order from smallest to largest)
3. Median temperature 2 years ago,
Median = middle number of the series.
Arrange numbers from lowest to highest. As this series contains even
numbers of entries, so median is average of middle numbers. So, (13+17)/2 = 15
