Q. 3. The relative humidity (in ) of a certain city for a month of days was as follows:
98.1 98.6 99.2 90.3 86.5 95.3 92.9 96.3 94.2 95.1
89.2 92.3 97.1 93.5 92.7 95.1 97.2 93.3 95.2 97.3
96.2 92.1 84.9 90.2 95.7 98.3 97.3 96.1 92.1 89
(iii) What is the range of this data?
Range of a given data = Highest observation - Lowest Observation
Highest recorded humidity = 99.2%
Lowest recorded humidity = 84.9%
Therefore range of the given data = 99.2 - 84.9 = 14.3%
