              example 2:  The approximate heights of 42 students (in cm) from class V are listed below:
                            142          145          150          152          142          142          148

                            145          155          150          150          152          145          145
                            155          152          152          155          148          148          150
                            145          150          155          150          145          145          148
                            142          145          142          155          148          150          148
                            142          152          150          150          155          142          142

              Tabulate the above data using tally marks and then answer the following questions.
                    (a)  What is the approximate height of the least number of students?

                    (b)  What is the approximate height of the most number of students?

                    (c)  How many students have 148 cm height approximately?

                    (d)  How many students have 155 cm height approximately?
              Solution:

                             Height (in cm)                    tally marks                    No. of students

                                   155                                 |                              6
                                  total                                                              42

                    (a)  152 cm is the approximate height of the least number of students.

                    (b)  150 cm is the approximate height of the most number of students.
                    (c)  6 students have height 148 cm approximately.

                    (d)  6 students have height 155 cm approximately.
