                • Drawing and presenting: Draw two columns representing the category and the data. Make the
                symbols according to the considered scale to represent the frequencies. If the frequency is not
                a whole, then the symbol can be divided into halves, quarters, etc., depending on our

                requirement to represent the fractional part.
            During COVID, online classes were in rampant use. Look at                    Activity       Time spent
            the data representing the average hours spent by students              Online classes         4 hours
            of a particular school on different activities. Make a suitable
            pictograph for this data.                                              Using gadgets          4 hours

            All data given in the tabular form talks about time, so let us
                                                                                   Sleeping               9 hours
            use the picture of a clock        to represent time. If we assume
                                                                                   Yoga and swimming      2 hours
            1       = 2 hours, then obviously 1 hour will be represented by        TV                     3 hours

            half picture of the clock  . Let us represent the data from the

            table pictographically using the chosen symbol.

            Example 4: The table given below shows the number of newspapers supplied by a distributor over
            a period of 7 months.

             Months                 January    February     March        April       May         June        July

            Prepare a pictograph to represent the above information and then answer the following questions:
                       (a)  In which months were the same number of newspapers supplied?

                        (b)  In which month were the least number of newspapers supplied?

                        (c)  How many newspapers were supplied over a period of 7 months?
