This example analyzes the relationship between a student's vocabulary and their reading frequency, demonstrating basic methods of correlation analysis. Key mathematical concepts include correlation coefficient, scatter plot, and linear regression. GeoGebra commands such as FitLineY and PMCC are used for data fitting and analysis. Suitable for middle school and above students to learn statistical knowledge.

AI Drawing Prompt Reference

Create a scatter plot with reading frequency on the x-axis and vocabulary size on the y-axis, containing about 20 data points. Add a best-fit line through the points and display the correlation coefficient. Place two data entry tables on the right or below, each with 20 rows for two columns of data. Surround each table with thin grid lines forming rectangular areas, with horizontal and vertical lines creating table cells.
