What visualization method is best for illustrating the relationship between weekly workout hours and average sleep hours?

• A. Histogram
• B. Scatterplot
• C. Pie chart
• D. Box plot

Answer: (B)

A scatterplot is the most appropriate visualization method for illustrating the relationship between two quantitative variables, such as weekly workout hours and average sleep hours. This type of plot allows each data point to represent an individual observation, showing how one variable is affected by the other. By plotting workout hours on one axis and sleep hours on the other, you can visually assess trends, patterns, and any potential correlation between the two variables. In contrast, histograms are used for displaying the distribution of a single quantitative variable rather than the relationship between two variables. Pie charts are effective for showing proportions of a whole across categorical data, making them unsuitable for this type of analysis. Box plots summarize data distributions using quartiles and can indicate the median and variability within a single quantitative variable but do not effectively illustrate relationships between multiple variables. Therefore, the scatterplot is uniquely suited to explore the relationship between weekly workout hours and average sleep hours.
