Scatter Plot (Linear) - Trend to Correlation Direction (Level 1)

This math topic focuses on understanding and identifying the types of correlation in scatter plots. Specifically, the problems cover recognizing positive, negative, and no correlation based on given scenarios about the relationship between two variables (e.g., temperature and sales, class size and grades, exam length and marks). Each problem provides a real-world context where students must decide the nature of the correlation between the changing variables, enhancing their ability to interpret data and trends using scatter plots.
