Question

data The heights of 50 students, measured to the nearest centimetres, have been found to be as follows: 161 168 161 159 150 154 165 154 162 150 151 162 164 171 165 158 154 156 172 160 170 153 161 170 165 166 168 165 164 154 152 153 156 158 162 160 161 173 166 161 159 162 167 168 159 158 153 154 159 (0) Represent the data given above by a grouped frequency distribution table, taking the class intervals as 160-165, 165-170, etc. (ii) What can you conclude about their heights from the table? rin​

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.
