Question 4: The heights of 50 students, measured to the nearest centimetres, have been found to be as follows:
161 150 154 162 164 171 153 159 161 154 152 153 161 159 162 165 168 165 158 170 162 156 158 167 168 161 154 162 154 156 172 165 166 168 162 160 161 159 158 153 150 151 160 170 165 164 173 166 154 159
- Represent the data given above by a grouped frequency distribution table, taking the class intervals as 160 – 165, 165 – 170, etc.
- What can you conclude about their heights from the table?
