Checkpoint 2.1.1.
From each person who would like to participate, collect their height (in inches) and shoe size. Note that in the USA it is common for "women’s" shoe sizes to be 2 more than the similarly sized "men’s" show size so determine whether one group should add 2 or the other should subtract 2 to make comparisons similar. If anyone is sensitive about either of these, feel free to adjust these numbers as needed. Consider:
- Plot this data as ordered pairs on a graph.
- Comment on whether it might be reasonable to adjust the height data to be the number of inches from (say) 6 feet rather than just total inches tall. Replot.
- Notice any trends that the data points might illustrate.
- Suggest ways that trends might be expressed mathematically.
- How might a mathematical formula that describes the trend be utilized in practice?
