7.2  Representing data in tables

               In Tank B Jabu has 50 Syubunkin fish. He measured them and
               wrote his measurements in this tally table. It helps him to
               organise his measurements. He makes a mark (tally) in the
               appropriate place in the table. Have a look at what he did.

               1. What can you tell about the length of the fish from Jabu’s
                   tally table? Write down your story and compare it with
                   that of a classmate.

               2. Do you agree or disagree with the following statements?
                   Explain why.

                   (a) Most Syubunkins are between 5 cm and 8 cm long.
                   (b) Most Syubunkins are 4 cm long.
                   (c) The number of Syubunkins that are 3 cm long is the
                       same as the number of Syubunkins that are 6 cm long.

                   (d) Half of the Syubunkins are 5 cm up to 8 cm long.
               3. Jabu asks you to put together the information about the fish
                   in Tank A (that is, the fish on pages 88 and 89). Make a tally
                   table like the one above to show the lengths of the Hibuna
                   and Huna fish that you measured.
