Solution.    Frequency distribution: It tells how frequencies are distributed overvalues in a frequency distribution. However mostly we use frequency distribution to summarize categorical variables.

Age (in year) No.of patients
less than 10 0
less than 20 60+0 = 60
less than 30 42+60 = 102
less than 40 102+55 =157
less than 50 157+70 = 227
less than 60 227+53 =280
less than 70 280 +20 =300

 

Age (in year) No.of patients
More than or equal to 10
More than or equal to 20
More than or equal to 30
More than or equal to 40
More than or equal to 50
More than or equal to 60		 60+42+55+70+53+20 = 300
42+55+70+53+20 = 240
55+70+53+20= 198
70+53+20 = 143
53+20 = 73
20
