Let's Ponder (Discussion 3): It's a "Fair" Representation?

The diagram represents the sales of socks at the bookshop in the months of April and May. In April, she sold 10 pairs of socks.

To report the improved sales to the company, the bookshop auntie represented decided to represent the sales using a 'pictogram'.



Does the above "pictogram" give a fair representation of the socks sold in these 2 months?
Give a reason to your answer.

What would you suggest to the bookshop owner to present the sales in an 'objective' manner?

  1. No. Making the sock bigger isn't accurate, as you can see, the bigger sock is actually 9 times bigger than the small one. She should just put more pictures of sockls to represent more socks sold

    No. As it can represent that she sold huge socks instead of more socks.
    I would suggest to make a graph which uses socks as the unit for the amount of socks sold.

  3. No, some people may not understand what she was trying represent.

    No it's not. The socks are supposed to be the same size, but in different numbers.

    No. It can represent that she sold larger socks in May than in April.
    I suggest using 1 sock representing an amount of socks.

    they should not make the sock look bigger instead just add more socks and each socks represent an amount of socks or they could label the axis,making it more easier to understand

    A pictogram requires the same picture to be used. Not a up-sized picture, just more of the same picture.

    No, the socks are supposed to be of the same size. If the socks are too big, it will be considered as the 'shortcut' method and it is wrong. The socks should be the same size. If she sells more socks during a certain month, she should just add in more socks instead of just drawing one big one.

    1. She should instead, put 9 more smaller socks instead of doing it the wrong way.

    No, it is not fair. The socks are not the same size. This makes it unclear on how much more socks were sold. Instead of using a picture of a big sock, they should have filled the 9 boxes with socks that have the same size as the first sock.

    No. A real pictogram is like a dot diagram, except is uses pictures to represent a specific value, like 1 pair of socks on the pictogram represents 1 pair of actual socks sold. This diagram is different, increasing the size of 1 pair of socks to represent the number to socks sold.

    What the auntie can do is create a actual pictogram that uses the number of pairs of socks to represent the number of actual socks sold, instead of increasing the size of 1 pair of socks to represented the number of socks sold.
