Question

The heights of 50 students, measured to the nearest centimetres, have been found to
be as follows:
161 150 154 165 168 161 154 162 150 151
162 164 171 165 158 154 156 172 160 170
153 159 161 170 162 165 166 168 165 164
154 152 153 156 158 162
161 173 166
161 159 162 167 168 159 158 153 154 159
(1) Represent the data given above by a grouped frequency distribution table, taking
the class intervals as 160-165, 165-170, etc.
(2) What can you conclude about their heights from the table?
160​

Answer 1

Answer:

Height (in cm) Frequency

150−155 12

155−160 9

160−165 14

165−170 10

170−175 5

Total 50

(i) The above table is the grouped frequency distribution.

(ii) Students with 160−165cm heights are maximum i.e. 14 students.
