Question

The following table gives the height of trees: Height No. of trees Less than 7 26 Less than 14 57 Less than 21 92 Less than 28 134 Less than 35 216 Less than 42 287 Less than 49 341 Less than 56 360 Draw &#x2018;less than&#x2019; ogive and &#x2018;more than&#x2019; ogive.

Less than method, it is given that:

Height	No. of trees
Less than 7	26
Less than 14	57
Less than 21	92
Less than 28	134
Less than 35	216
Less than 42	287
Less than 49	341
Less than 56	360

Now we mark the upper class limits along x-axis and cumulative frequency along y-axis. Thus, we plot the points: (7,26); (14,57); (21,92); (28,134); (35,216); (42,287); (49,341); (56,360)

More than method: We will prepare the cumulative frequency table by more than method as given below:

Height	Frequency	Height more than	Cumulative frequency
0-7	26	0	360
7-14	31	7	334
14-21	35	14	303
21-28	42	21	263
28-35	82	28	226
35-42	71	35	144
42-49	54	42	73
49-56	19	49	19

Now we mark,

On x-axis lower class limit and on y-axis Cumulative frequency

Thus, we plot graph as (0,360); (7,334); (14,303); (21,263); (28,226); (35,144); (42,73); (49,19)
