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?

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

1. no.The pictogram should be in constant unit ,so the socks should be the same sign

2. No. The viewers would be confused as to what we see and measure, the number of squares occupied or the area of the socks.

Use a pictogram instead.

4. No. The pictogram should have a constant unit that represents a constant number thus the socks/unit in this case should be stacked on top of each other.

i.e. For May, the number of socks is 9 boxes, thus there should be 9 socks stacked on each other.

5. No. Data represented by a picture should all be at the same size in a pictogram for a fair representation.

Group 3 ~^^

6. There is no numerical unit to represent the pictogram, and both socks do not start from the bottom.

7. The socks are getting bigger without a key to tell the difference so as to report the sales.

Use a pictogram.

8. group 1 :

no it does not because the increase in size of the socks might not be accurate and it is misleading

have each representation of the socks the same size just add in multiple sock representations

9. Group 1
the pictures should be the same size

10. No the data should be increased in numbers not size

11. The graph should be more specific by having the same size socks. The data should be represented in a pictogram instead.
Group 2

12. No. The pictogram does not give a fair comparison as the size of the socks should be the same and the thing that is changed should be the number of socks ~

13. No. There is no numbers to represent the sock. Sometimes she may cheat by just only increasing the size by a lot but the improvement might not be that significant. She have to show numbers to show proof. And both socks did not start from the bottom of the graph.
