Praxis 5003 Practice Test Practice Question
Which of the following lists the five terms known as the five-number summary used to describe a set of data displayed in a boxplot?
Correct Answer: D
Rationale: The five-number summary provides essential insights into a dataset's distribution and is represented in a boxplot. It includes the minimum (lowest value), first quartile (25th percentile), median (50th percentile), third quartile (75th percentile), and maximum (highest value).
Option A incorrectly lists the mean and mode, which are not part of the five-number summary. Option B includes the mean, mode, and standard deviation, which are measures of central tendency and variability, not part of the five-number summary. Option C also misplaces the mean and mode, substituting them for the first and third quartiles, which are crucial for understanding data spread.
