①本范例演示学生如何通过对比两个测试分数,分析一个虚构学生的表现差异;②涉及的核心数学概念包括均值、标准差、正态分布、条形图等;③作图要点:使用了 Textfield, Integral, Segment, Line, Intersect, Point, Mirror 等命令和对象,如 σ, σ_2, μ, inputBox1, f, sm, sd, hm, hd, h, s, a, b, A, B, StatPercentile, HistoryPercentile, C, D, E, F, TransformedPercentile, d, e, g, text1, text2, text3, text4, investigate, H_m, S_m, G, c, H, i, I, J, j, k 等进行数据分析和可视化;④适合高中数学教学,用于概率统计和数据分析入门教学。
