The following is the distribution of weights (in kg) of 40
persons :
Weight (in kg). 40-45 45-50 50-55 55-60 60-65 65-70 70-75 75-80
No. of persons 4 4 13 5 6 5 2 1
Construct a cumulative frequency distribution (of the less
than type) and (more than type) table for the data
above.Also find median from the graph.

Given :  distribution of weights (in kg) of 40  persons :

To find : Construct a cumulative frequency distribution (of the less

than type) and (more than type) table for the data . and draw graph , find median

Solution:

Weight (in kg).  Frequency      Less Than         More than

40-45                      4                     4                       40

45-50                      4                     8                       36

50-55                     13                    21                      32

55-60                      5                    26                     19

60-65                      6                    32                      14

65-70                      5                     37                      8

70-75                      2                     39                      3

75-80                      1                     40                       1

Median =   50  +  5 * (20  - 8)/13

= 50 + 4.6

= 54.6

Median from Graph also approximate 54.6

Less than ogive

The points with the upper limits of the class are plotted on x axis  and the corresponding less than cumulative frequencies on y axis.

The points are joined by free hand smooth curve to give less than cumulative frequency curve or the less than Ogive

More than ogive

The points with the Lower limits of the class are plotted on x axis  and the corresponding more than cumulative frequencies on y axis.

The points are joined by free hand smooth curve to give more than cumulative frequency curve or the More than Ogive
