概率统计几何作图函数图像
这个活动演示如何从 popcorn 数据中创建柱状图。核心数学概念包括数据整理、频率统计和柱状图绘制。作图要点包括使用 Shuffle、Sort、CountIf 等 GeoGebra 命令来组织数据，并用 Bar 命令绘制柱状图。适合 6-8 年级学生用于统计学习实践。

AI 绘图提示语参考

请绘制一个柱状图，包含五个柱子，分别对应数据区间：x大于215、205到215、195到205、185到195以及小于等于185。柱子高度由统计计数决定。同时绘制五个输入框，以及一个使用输入框数值绘制的柱状图，并添加坐标轴、刻度、网格和垂直文本“Numbers of Bags”。
以上提示语为根据原始绘图命令整理而来，仅供参考。
