Scatter Plot (Linear) - R Value to Correlation Direction and Strength (Level 1)

This math topic focuses on interpreting correlation coefficients in scatter plots. Specifically, it involves identifying the direction and strength of correlation based on given R values. Students are asked to determine whether the correlation is strong, medium, weak, positive, negative, or nonexistent based on numerical R values provided in various problems. This is essential for understanding data relationships in scatter plots, a fundamental concept in statistics.
