Given : the age distribution of patients of malaria in  a village during a particular month:

Age (in years) 5-14 15-24 25-34 35-44  45-54 55-64  

Number of cases  6       11     21        23          14    5  

To Find :  the average age of the patients.​  

Solution:  

Age (in years)  Mean Age   d=(Mean - 29.5)/10   f              d.f  

5-14                   9.5                   -2                           6           -12  

15-24                19.5                   -1                           11           -11  

25-34               29.5                  0                           21            0  

35-44               39.5                   1                           23           23  

45-54               49.5                   2                          14            28

55-64               69.5                   3                          5             15    

                                                                           80            43

Mean = 29.5  +  43 * 10 /80

= 29.5 + 5.375  

= 34.875  

average age of the patients = 34.875
