# A Turkey of a Graph

This news story could make for an engaging math task. The reporter even lists some questions students may have.

But what I really want to know is …

what is this?

Graphs should reveal information about a situation (e.g., relationships, trends). Does this graph do that? The pictograph is cute, but does it suit the data? Choice of format aside, what’s with the different symbols/scales between categories? The reader can compare pounds of mashed potatoes to pounds of vegetables (kind of) and litres of gravy to litres of cranberry sauce, but what conclusion can he or she draw from comparing the mashed potato category to the gravy category (or to turkeys, rolls, or pies, for that matter)? And the spacing? At first glance, it looks like there are 80, not 100, pounds more mashed potatoes than vegetables. But wait–there’s an extra partial column of broccoli. At least it wasn’t Brussels sprouts.

Happy Thanksgiving.

1. Yeah, that’s a pretty pointless graph. I think we’d need to talk to their teacher and see if they talked about the REASON we use bar graphs (or graphs in general).

2. Blimey? That’s one bizarre histogram/pictogram hybrid that makes entirely no sense at all! How could someone actually think that’s ok to print?
