Detailed Solution & Explanation

**Purpose and usage of Scatter Diagram:** A scatter diagram (also called scattergram or scatter plot) is a graphical tool used to: - Plot pairs of observations (xi,yi)\displaystyle (x_i, y_i) on a two-dimensional graph - Study the relationship between two variables **Type of data:** Scatter diagrams are used for **quantitative data** (numerical data with measurable values), because: - We need actual numerical values to plot on X\displaystyle X and Y\displaystyle Y axes - The position of each point represents the magnitude of both variables - Both variables must be measurable/numerical Qualitative data (like grades A, B, C or colors) cannot be directly plotted on a scatter diagram; for such data, Spearman's rank correlation is used after assigning ranks. Hence, **Option A** is the correct answer.
