Question

For the data given below, prepare a frequency distribution table with classes 100−110, 110-120, etc.

125	108	112	126	110	132	136	130	140	155
120	130	136	138	125	111	112	125	140	148
147	137	145	150	142	135	137	132	165	154

Answer 1

In the form of frequency distribution, the given data can be arranged as follows.

Class Interval	Telly Marks	Frequency
100 − 110		1
110 − 120		4
120 − 130		5
130 − 140		10
140 − 150		6
150 − 160		3
160 − 170		1
		$\sum _{}^{}f=30$
