The violin plot is very powerful as it displays the range of a dataset and the probability density of a value in the same view.

Lathe 3 is performing with relatively less variation than Lathe 2 however, it is centered on the lower side of the specification and is making shafts below specification.Comparison between violin plot and box + whisker plot.

Lathe 2 appears to have excess variation, and is making shafts below the minimum diameter.

Lathe 1 appears to be making good parts, and is centered in the tolerance.

The design specification is 18.85 +/- 0.1 mm.Дiameter measurements from a sample of shafts taken from each roughing lathe are displayed in a box and whisker plot in Figure 2.ДЇigure 2 Box and Whisker Plot Lathe Comparison Example Suppose you wanted to compare the performance of three lathes responsible for the rough turning of a motor shaft. Right figure: For comparison, a histogram of the data is also shown, showing the frequency of each value in the data set. The median value is displayed inside the 'box.' The maximum and minimum values are displayed with vertical lines ('whiskers') connecting the points to the center box. Left figure: The center represents the middle 50%, or 50th percentile of the data set, and is derived using the lower and upper quartile values.

The data represented in box and whisker plot format can be seen in Figure 1. Note: For a data set with an even number of values, the median is calculated as the average of the two middle values. Maximum value: The largest value in the data setДЇor example, given the following 20 data points, the five required statistics are displayed.Third quartile: The value above which the upper 25% of the data are contained.Median value: The middle number in a range of numbers.Second quartile: The value below which the lower 25% of the data are contained.

Minimum value: The smallest value in the data set.

Sources that are related to each other in some way. Use box and whisker plots when you have multiple data sets from independent Plots allow for comparison of data from different categories for easier, more effectiveДecision-making. Why Use a Box and Whisker Plot?Д«ox and whisker plots are very effective and easy to read, as they can summarize dataДЇrom multiple sources and display the results in a single graph. Plot can provide additional detail while allowing multiple sets of data to be displayed in the same graph. In most cases, a histogram analysis provides a sufficient display, but a box and whisker Quality Glossary Definition: Box and whisker plotДЄlso called: box plot, box and whisker diagram, box and whisker plot with outliersДЄ box and whisker plot is defined as a graphical method of displaying variation in a set of data.
