Line Plots, Cats, and 5th Graders

If you were presented with this data about cat height, what could state about what was typical of the cats in this group. Could you find the mean, the mode, the range, and the median? Could you tell what fraction and percent of the cats were taller than 5.5 inches but less than 8 inches? (Click on the picture if you need a full-size view.)

I just measured my cat and she is 10 inches tall at the shoulder. She is a smallish seven-year-old female cat. Does that make you think anything about what kind of sample this might have been?

If you have a cat, could you measure their height and reply? We'll stick to inches since the chart was created in that unit:-}
