Question 4 (i)
The heights of 50 students, measured to the nearest centimeters, have been found to be as follows:
161150154165168161154162150151162164171165158154156172160170153159161170162165166168165164154152153156158162160161173166161159162167168159158153154159
(i) Represent the data given above by a grouped frequency distribution table, taking the class intervals as 160 - 165, 165 - 170, etc.
(i) A grouped frequency distribution table has to be constructed taking class intervals 160−165, 165−170, etc. By observing the data given above, the required table can be constructed as follows.
