    They decided that the captain of the first team will be the one with the longest
                       name, i.e., the one with the most letters. The captain of the second team will be the
                       one with the shortest name, i.e., the one with the fewest letters.

                         1.  Find out  the  captains  of the  2 teams.  How many  letters  are there  in their
                            names?

                    The information collected in the form of numerical figures in a survey is known as data.

                    recording data

                    Data can be recorded in a table using tally marks which is a quick way of keeping

                    track  of numbers  in groups  of five. We  use  vertical  lines  for tally  marks.  We  draw
                    one vertical line (l) for every data point (number). For four data points, we draw four
                    vertical lines. The fifth data point is represented by a line across the previous four.

                    Look at the following table. It represents students of class 3 who have birthdays in the
                    months of a year.

                       Month      tally marks Number of students            Month      tally marks Number of students

                    Now, the following questions can be answered by observing the above tables.

                      a.  How many months have birthdays of five students each?  April and November

                      b.  Which month has birthdays of the most students?                                      September

                      c.  Which month has birthdays of the least number of students?                                   July

                                                                                                                 207
