Measures of dispersion, like range, variance, and standard deviation, make data more relatable for Year 9 students. Here’s how they help:
Understanding Spread: These measures show how data is clustered together or spread apart. For example, knowing the range (Range = Max - Min) helps you quickly see where the most extreme values are in the data.
Making Comparisons: Variance and standard deviation help us compare different sets of data. If the standard deviation is high, it means the data points vary a lot, which can lead to some interesting discoveries.
Real-world Applications: These measures help students think critically by using statistics in real-life situations. This makes the lessons more interesting and relevant. It also helps students learn how to understand and interpret data better.
