____ are used to visually examine the relationship between two quantitative variables. (a) Bar graphs

(b) Pie graphs

(c) Line graphs

(d) Scatterplots

✅ Correct option: (d) Scatterplots

Explanation:

A scatterplot is a graphical display used to examine the relationship between two quantitative variables. Each point on the graph represents a pair of values, one on the x-axis and one on the y-axis. Scatterplots help identify patterns such as positive correlation, negative correlation, or no relationship between variables. Bar graphs and pie charts are used for categorical data, while line graphs typically show trends over time. Scatterplots are uniquely suited for studying relationships between numerical variables, making them essential in correlational research.
