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...
In descriptive statistics, the interquartile range tells you the spread of the middle half of your distribution.Quartiles segment any distribution that’s ordered from low to high into four equal parts. The interquartile range (IQR) contains the second and third quartiles, or the middle half ...
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 (...
Example: Using the interquartile range to find outliers We’ll walk you through the popular IQR method for identifying outliers using a step-by-step example. Your dataset has 11 values. You have a couple of extreme values in your dataset, so you’ll use the IQR method to check whether th...
In this article, you will not only have a better understanding of how to find outliers, but how and when to deal with them in data processing.
This leads to two halves with an even set of numbers, so you can follow the steps above to find the IQR. Back to Top Box Plot interquartile range: How to find it Example question: Find the interquartile range for the above box plot. Find Q1. Q1 is represented by the left hand edge...
How to interpret a boxplot graph? In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25...
