17	20	25	28	18	10	24	20	21	10	7	18	28	24	20
14	23	25	34	22	5	33	23	26	29	13	36	11	26	11

15	27	17	21

Convert the above data in a frequency distribution making classes of 5-9, 10-14 and so on.

Answer 1

Quantity of Milk (kg)	Tally Bar	Frequency (f)
5 − 9		7
10 − 14		10
15 − 19		13
20 − 24		18
25 − 29		8
30 − 34		5
35 − 39		3
		Ʃf = 64
