Apr 16, 2020 · In the box and whisker diagram, it has five pieces of information,(also called a five-number summary). Elements of a Box and Whisker Plot The elements required to construct a box and whisker plot outliers are given below. Minimum value (Q0 or 0th percentile) First quartile (Q1 or 25th percentile) Median (Q2 or 50th percentile)
In descriptive statistics, a box plot or boxplot (also known as box and whisker plot) is a type of chart often used in explanatory data analysis. Box plots visually show the distribution of numerical data and skewness through displaying the data quartiles (or percentiles) and averages. Box plots show the five-number summary of a set of data: including the minimum score, first (lower) …
The five values that make up a box and whisker plot are: 4. The five values in question 3 are called the What is the five number summary of the following box and whisker plot? Create a box and whisker plot with the following set of data: 3, 2, 3, 4,...
The Box and Whisker consists of two parts—the main body called the Box and the thin vertical lines coming out of the Box called Whiskers . Check out live examples of Box and Whisker Chart in our charts gallery and JSFiddle gallery. Constructing a Box and Whisker chart: To understand how a Box and Whisker chart is constructed, we have to first arrange our data in ascending …
The key parts needed to draw a box-and-whisker plot are: Median - the middle number of a data set that is ordered from least to greatest. Lower and upper quartiles - values that divide the data set into four sections. Lower and upper extremes - the smallest and largest values in the data set.Dec 3, 2015
A box and whisker plot shows the minimum value, first quartile, median, third quartile and maximum value of a data set.
Box-and-whisker plots are a handy way to display data broken into four quartiles, each with an equal number of data values. The box-and-whisker plot doesn't show frequency, and it doesn't display each individual statistic, but it clearly shows where the middle of the data lies.
A box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value. We use these values to compare how close other data values are to them.

The first step in constructing a box-and-whisker plot is to first find the median (Q2), the lower quartile (Q1) and the upper quartile (Q3) of a given set of data.
The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median. The whiskers go from each quartile to the minimum or maximum.
The five number summary of a set of data is the minimum, first quartile, second quartile, third quartile, and maximum. The lower quartile, also known as Q1, is the median of the lower half of the data.Nov 28, 2020
A summary consists of five values: the most extreme values in the data set (the maximum and minimum values), the lower and upper quartiles, and the median. These values are presented together and ordered from lowest to highest: minimum value, lower quartile (Q1), median value (Q2), upper quartile (Q3), maximum value.Mar 31, 2021

The upper and lower whiskers represent scores outside the middle 50% (i.e. the lower 25% of scores and the upper 25% of scores). This is the box plot showing the middle 50% of scores (i.e., the range between the 25th and 75th percentile).
When the median is in the middle of the box, and the whiskers are about the same on both sides of the box, then the distribution is symmetric. When the median is closer to the bottom of the box, and if the whisker is shorter on the lower end of the box, then the distribution is positively skewed (skewed right).
The median is the average value from a set of data and is shown by the line that divides the box into two parts. Half the scores are greater than or equal to this value and half are less.
Box plots are useful as they show the dispersion of a data set. In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. The smallest value and largest value are found at the end of the ‘whiskers’ and are useful for providing a visual indicator regarding the spread ...
Box and whisker plots are very effective and easy to read, as they can summarize data from multiple sources and display the results in a single graph. Box and whisker plots allow for comparison of data from different categories for easier, more effective decision-making.
When to Use a Box and Whisker Plot. Use box and whisker plots when you have multiple data sets from independent sources that are related to each other in some way. Examples include: Test scores between schools or classrooms. Data from before and after a process change. Similar features on one part, such as camshaft lobes.
In most cases, a histogram analysis provides a sufficient display, but a box and whisker plot can provide additional detail while allowing multiple sets of data to be displayed in the same graph.
