Use-Cases of Box Plot
- Box plots provide a visual summary of the data with which we can quickly identify the average value of the data, how dispersed the data is, whether the data is skewed or not (skewness).
- The Median gives you the average value of the data.
- Box Plots shows Skewness of the data-
a) If the Median is at the center of the Box and the whiskers are almost the same on both the ends then the data is Normally Distributed. b) If the Median lies closer to the First Quartile and if the whisker at the lower end is shorter (as in the above example) then it has a Positive Skew (Right Skew). c) If the Median lies closer to the Third Quartile and if the whisker at the upper end is shorter than it has a Negative Skew (Left Skew).
- The dispersion or spread of data can be visualized by the minimum and maximum values which are found at the end of the whiskers.
- The Box plot gives us the idea of about the Outliers which are the points which are numerically distant from the rest of the data.
Box Plot
Box Plot is a graphical method to visualize data distribution for gaining insights and making informed decisions. Box plot is a type of chart that depicts a group of numerical data through their quartiles.
In this article, we are going to discuss components of a box plot, how to create a box plot, uses of a Box Plot, and how to compare box plots.
