Selected Answer: B

pg 130 CBDA guide: Bivariate plots: bar graphs, scatter plots, boxplots, correlation plots (heat maps), and others. Bar graphs and scatter plots are good for recognizing trends, boxplots are good for identifying outliers, and correlation heat maps show interrelationship between variables. Research: A box plot (also known as a box-and-whisker plot) visually represents the distribution of data based on these quartiles and includes the minimum and maximum values, making it an effective tool for summarizing and displaying the spread and center of a dataset.
