What’s the difference in the range of temperatures recorded last year and the range of temperatures recorded two years ago

aksik [14]

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 = 11Â°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
