I’m a sucker for all things Valentine and hearts. So why wouldn’t I have an AP Stats activity using Sweetheart conversation hearts? This year, my students endulge me better than most, at least feinting enthusiasm for these corny activities.
This activity was all about the proportion of pink hearts. The big question was, “What is the true proportion of pink Sweetheart conversation hearts?” They had to count the number of pink hearts and then determine a sample proportion for their box…we had to discuss our willingness to accept each box as a random sample from the population of all Sweetheart conversation hearts.
From there, they began their introduction to inference methods via the confidence interval. Using their sample value, they explored the possible shape of the sampling distribution, how it related to their previous understanding of sampling distributions, what conditions might need to be in place, etc.
The next step is to work on interpreting the confidence interval as well as the confidence level…their first foray into technical writing!
