Create a boxplot from a five-number summary. Use a boxplot to identify and interpret quartiles. Identify the median and the IQR of a distribution from a boxplot. Now we want to focus on what a boxplot doesnottel
In “Quantifying Variability Relative to the Median” and Quantifying Variability Relative to the Mean,” we focus on describing the spread of a distribution more precisely.We begin with describing spread about the median.Example Two Sets of Exam Scores Consider the following two distributions of ...

The interquartile range (IQR) is a measure of statistical dispersion that is based on dividing a data set into quartiles. Specifically, it is the difference between the upper quartile (Q3) and the lower quartile (Q1) of a data set. To calculate the IQR, one must first arrange the data...

Because it’s based on the middle half of the distribution, it’s less influenced by extreme values.Visualize the interquartile range in boxplotsA boxplot, or a box-and-whisker plot, summarizes a data set visually using a five-number summary....
Example question: Find the interquartile range for the above box plot. Find Q1. Q1 is represented by the left hand edge of the “box” (at the point where the whisker stops). In the above graph, Q1 is approximately at 2.6. Find Q3. Q3 is represented on a boxplot by the right ...
