Jared worked through problems in which he had to calculate the measurements of center of the dataset presented (mean, median, mode, midrange). This is simply arithmetic, and as I had noted last week, Jared really knows his elementary statistics! But the underlying exercises focused on whether these measurements of center were useful in the specific contexts (e.g. for some datasets, variations in time are more important than the actual numbers). After each problem we discussed these points, and Jared was spot on every time.
