Lets see how to plot the Excel Boxplot in this chapter.

Box plot represents the minimum, maximum, median, first quartile and third quartile in the data set. Boxplot is a convenient way of graphically depicting groups of numerical data through their quartiles. 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.Boxplots are a measure of how well distributed is the data.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.ĭiameter measurements from a sample of shafts taken from each roughing lathe are displayed in a box and whisker plot in Figure 2.įigure 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 setįor 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.

This makes it easy to see how data is distributed along a number line, and it's easy to make one. Second quartile: The value below which the lower 25% of the data are contained A box and whisker plot is a diagram that shows the statistical distribution of a set of data.Minimum value: The smallest value in the data set.
