This GeoGebra example demonstrates how to calculate and compare different types of averages, including arithmetic mean, mode, and median. Students can experiment with different data sets and observe the changes in different averages. This example is suitable for middle school mathematics education, particularly for teaching statistics and probability. Through this example, students can learn how to use GeoGebra to calculate and compare averages, understand the meaning and application of different averages.

AI Drawing Prompt Reference

On a single coordinate workspace, create multiple interactive UI elements: place several left-side speech bubbles at different heights to prompt the user, then add a set of text input fields in sequence in the middle area, each accompanied by brief nearby bubbles. Include several dropdown selection controls beside the inputs so the user can choose data items. Add one additional speech bubble to guide a final comparison step. At the end, draw a vector-like arrow on the canvas to represent the direction defined by two points, and include an interactive count/boolean-style control for whether an item is clicked.
