In collections Statistics Step Through Applets
This applet demonstrates the steps involved in creating a quantitative frequency distribution. Students can select different data sets and follow the process to build a frequency distribution table. Key statistical concepts such as data grouping and frequency calculation are covered. Using GeoGebra commands like Mod, Sequence, CountIf, etc., the construction process is dynamically illustrated. Suitable for introductory statistics learners.
