The table shows the mean monthly temperatures in alcudia for the last 2 years in degrees celsius. °c jan feb mar apr may jun jul aug sep oct nov dec last year 9 10 11 14 19 22 27 29 21 18 11 6 2 years ago 7 11 10 13 17 23 25 25 20 18 12 9 what is the difference in the range of temperature between the two years? °c what was the modal temperature last year? °c what was the median temperature 2 years ago? °c

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

The answer is b) 32 your welcome
