Question

Draw an ogive by less than method for the following data:

Answer 1

We first prepare the cumulative frequency distribution by less than method as given below:

Now we mark the upper class limits along x-axis and cumulative frequency along y-axis. 

Thus,

we plot the points (1,4); (2,13); (3,35); (4,63); (5,87); (6,99); (7,107); (8,113); (9,118); (10,120)
