Answer: To visualize the relationship between multiple pairs of variables
**Correct Option: D. To visualize the relationship between multiple pairs of variables** **Explanation:** A pair plot is a matrix of scatter plots that allows for the visualization of pairwise relationships among several numerical variables within a dataset. This technique is particularly useful for: - **Identifying correlations:** It helps in spotting positive, negative, or no correlation between variables. - **Detecting outliers:** Scatter plots within the pair plot can reveal outliers. - **Understanding data distributions:** Typically, the diagonal plots display histograms or kernel density plots for individual variables. **Why other options are incorrect:** - **A. To display the distribution of a single variable:** Histograms or box plots are more suitable for this purpose. - **B. To visualize hierarchical data:** Treemaps are the go-to for hierarchical data visualization. - **C. To show trends over time:** Line plots or time series plots are better options for displaying trends over time.
