In exploratory data analysis,a _____________  can be used to illustrate the median,quartiles,and extreme values.
A) range
B) boxplot
C) Z score

Quizplus · Accepted Answer

A boxplot is a graphical representation that can be used to efficiently summarize the distribution of a variable. It displays the median, quartiles and extreme values (outliers) of the data in a visually appealing manner. The range (A) only shows the extreme values while Z score (C) and population variance (D) are measures of central tendency and variability respectively, but do not provide a clear illustration of the distribution of the data.
