This summary includes five key data points: The smallest number (minimum) The first quartile (25 mark) The middle number (median) The third quartile (75 mark) The largest number (maximum) Together, these five values highlight your data’s distribution’s shape, spread, and central tendency. The center line in the box shows the median for the data. See the 'Comparing outlier and quantile box plots' section below for another type of box plot. Use the information below to generate a citation. The term box plot refers to an outlier box plot this plot is also called a box-and-whisker plot or a Tukey box plot. Then you must include on every digital page view the following attribution: If you are redistributing all or part of this book in a digital format, Then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a print format, Each box chart displays the following information: the median, the lower and upper quartiles, any outliers (computed using the interquartile range), and the minimum and maximum values that are. If ydata is a vector, then boxchart creates a single box chart. Boxplots can tell you about your outliers and. Flier points are those past the end of the whiskers. A boxplot, also known as a box plot, box plots or box-and-whisker plot, is a standardized way of displaying the distribution of a data set based on its five-number summary of data points: the minimum, first quartile Q1, median, third quartile Q3 and maximum. The whiskers extend from the box to the farthest data point lying within 1.5x the inter-quartile range (IQR) from the box. Want to cite, share, or modify this book? This book uses the boxchart (ydata) creates a box chart, or box plot, for each column of the matrix ydata. The box extends from the first quartile (Q1) to the third quartile (Q3) of the data, with a line at the median. So, totaling these up, between the top and bottom horizontal bars, you’ve got 99.3 of the population. This book may not be used in the training of large language models or otherwise be ingested into large language models or generative AI offerings without OpenStax's permission. The horizontal line at the the end of the a boxplot whisker marks 24.675 more of the population above the mean, and the bottom whisker marks off the same interval below the mean. A box and whisker plotalso called a box plotdisplays the five-number summary of a set of data. ![]()
