3.33
Due to our tight timeframe, no content homework this evening. In your reflection tonight, address the following:
Tonight, we touched on mean, mean absolute deviation, median, and interquartile range. As students learn to calculate and represent these quantities, how might we support them in developing both the procedural fluency with these quantities alongside the conceptual understanding that will help them know when and how to make use of them?
