Question

Find the median of the following data . clas interval O-20 20-40 40-60 60-80 80-100 100-120 frequency 9 16 24 15 4 2 .Also draw the Less than type ogive to the above data​

Answer 1

Answer:Mismatch in Data

Step-by-step explanation:

0- 20                  6

20 - 40              8

40 - 60              10

60 - 80              12

80 -100            6

100 - 120           5      

                         3

Class intervals given are  6

frequencies given are 7

So mismatch in data

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
