基于MATLAB的抽样分布理论实验开发
Experimental Development of Sampling Distribution Theory Based on MATLAB

本文利用MATLAB的界面设计功能对抽样分布理论构建了一个模拟实验界面，以可视化动态演示的形式呈现抽象的理论，将几种常见抽样分布的频数直方图与概率密度函数进行比较。在该界面中，学生可以自主进行实验操作，修改参数，观察多种情况下的实验结果。本项目实现了用户与界面的互动，省略了复杂的证明过程，从而帮助学生更好地理解抽样分布理论。
This paper uses the interface design function of MATLAB to build a simulation experiment interface for the theory of sampling distribution, presenting the abstract theory in a visual and dynamic demonstration form. It compares the frequency histograms and probability density functions of several common sampling distributions. In this interface, students can conduct experimental operations autonomously, modify parameters, and observe the experimental results under various conditions. This project achieves interaction between users and interfaces, omits complex proof processes, and helps students better understand the theory of sampling distribution.
