Certificate in Business Data Analytics (CBDA) — Question 58

A data scientist is performing statistical analysis and is interested in graphically depicting the data set according to the associated quartiles Minimum, First Quartile, Median, Second Quartile, Third Quartile.
Which technique would allow for the display of this statistical five number summary?

Answer options

• A. Gaussian distribution
• B. Box plot
• C. Scatter plot
• D. Multivariate histogram

Correct answer: B

Explanation

The box plot is specifically designed to display the five-number summary of a dataset, showing the minimum, first quartile, median, third quartile, and maximum. In contrast, Gaussian distribution, scatter plots, and multivariate histograms do not focus on quartiles or the five-number summary format, making them less suitable for this purpose.
