Application of Bullseye Diagram in Teaching of “Variance”
Abstract
Variance and standard deviation, as a kind of discrete function, are an important content in high school teaching, and they are widely used in data statistics. For high school students, they have difficulty understanding abstract concepts such as stability, volatility, and degree of dispersion when they are first exposed to discrete functions. In actual teaching, you can apply “bullseye chart” to “variance” teaching, and use abstract concept diagrams. Demonstration helps high school students to intuitively understand the concept of “variance” and the nature of dispersion.
