Building a Cumulative Frequency Graph

This GeoGebra example demonstrates how to construct a cumulative frequency graph from discrete data points, highlighting how the curve reflects the overall distribution as frequency accumulates. It focuses on key ideas from probability & statistics such as cumulative frequency (and cumulative distribution interpretation), mapping statistical quantities onto a graph, and using scatter/connected segments to visualize the cumulative trend. The construction uses GeoGebra commands Point and Segment to create and link key points and interval endpoints; the involved objects include k, f, g, A, B, C, a, b, n, and text1 to parameterize points/indices and annotate the graph. Suitable for middle and high school learners, introductory data analysis lessons, and classroom demonstrations of how to move from a frequency table to a cumulative frequency plot.
