Exercise 10: Interactive Exploration of Random Data Histogram and Confidence Int

① This example demonstrates how to generate random data in GeoGebra and dynamically visualize the relationship between a frequency distribution histogram and a confidence interval. ② Core mathematical concepts include frequency distribution, histograms, confidence intervals, and random sampling, forming the basis of statistical inference. ③ Construction highlights: from the summary, commands such as Random and RandomElement generate random numbers, Textfield and InputBox provide interactive inputs, TableText displays data tables, and a button (button1) triggers re-randomization. Objects include multiple points, segments, texts, and sliders, creating a dynamic statistical experiment environment where sample size and confidence level can be adjusted. ④ Suitable for high school or introductory college statistics courses, this example helps students intuitively understand sampling distributions, the meaning of confidence intervals, and how sample size affects interval width. It serves as an effective tool for classroom demonstrations or self-directed student exploration.
