About the lesson
This activity explores the calculations of the five figure summary: {min, Q1, median, Q3 and max}. How is an outlier determined? What is positive / negative skew? By physically dragging the maximum point students can determine when the whisker ‘breaks’ and an outlier is created. The connection between the dot plot and the box and whisker plot improves the visual power of this dynamic interaction.
