The interquartile range (IQR) measures the spread of the middle half of your data. It is the range for the middle 50% of yoursample. Use the IQR to assess the variability where most of your values lie. Larger values indicate that the central portion of your data spread out further. Con...
Back to Top How to Read a Box Plot: Steps A boxplot is a way to show a five number summary in a chart. The main part of the chart (the “box”) shows where the middle portion of the data is: the interquartile range. At the ends of the box, you” find the first quartile (...
Boxplots are drawn as a box with a line inside of it, and has extended lines attached to each of its sides (known as “whiskers”). The box is used to represent the interquartile range (IQR) — or the 50 percent of data points lying above the first quartile and below the third ...

Box and whisker plot is the process to abstract a set of data, which is estimated using an interval scale. Visit BYJU’S to learn the procedure of drawing box plots and whisker plots.
findoutlier <- function(x) { return(x < quantile(x, .25) - 1.5*IQR(x) | x > quantile(x, .75) + 1.5*IQR(x)) } Step 3: In ggplot2, label outliers in boxplots The next step is to use the code below to label outliers in ggplot2 boxplots: library(ggplot2) library(dplyr)...
For computing Z-scores, we need to determine mean (μ) and standard deviation (σ) of the data. After calculating Z-scores, we check if there are values with a score higher than the value of absolute 3, since 99.7% of data fall in the range from -3 to 3. In case we find them,...
The IQR is used to buildbox plots, simple graphical representations of aprobability distribution. For a symmetric distribution (so the median equals themidhinge, the average of the first and third quartiles), half the IQR equals themedian absolute deviation(MAD). Themedianis the corresponding meas...
