A box and whisker plot is defined as a graphical method of displaying variation in a set of data.In most cases, a histogram analysis provides a sufficient display, but a box and whiskerplot can provide additional detail while allowing multiple sets of data to be displayed in the same graph.

Why Use a Box and Whisker Plot?

Box and whisker plots are very effective and easy to read, as they can summarize datafrom multiple sources and display the results in a single graph. Box and whiskerplots allow for comparison of data from different categories for easier, more effectivedecision-making.

When to Use a Box and Whisker Plot

Use box and whisker plots when you have multiple data sets from independentsources 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
Data from duplicate machines manufacturing the same products

How to Make a Box and Whisker Plot

The procedure to develop a box and whisker plot comes from the five statistics below. You can also download the box and whisker plot template.

Minimum value: The smallest value in the data set
Second quartile: The value below which the lower 25% of the data are contained
Median value: The middle number in a range of numbers
Third quartile: The value above which the upper 25% of the data are contained
Maximum value: The largest value in the data set

For example, given the following 20 data points, the five required statistics are displayed.

Number	Data
1	113	Minimum value: 113
2	116
3	119
4	121
5	124
2nd quartile: 124
6	124
7	125
8	126
9	126
10	126
Median value: 126.5
11	127
12	127
13	128
14	129
15	130
3rd quartile: 130
16	130
17	131
18	132
19	133
20	136	Maximum value: 136

The data represented in box and whisker plot format can be seen in Figure 1.

Figure 1 Box and Whisker Plot Example

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 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.

Right figure: For comparison, a histogram of the data is also shown, showing the frequency of each value in the data set.

Box and Whisker Plot Example

Suppose you wanted to compare the performance of three lathes responsible for the rough turning of a motor shaft. The design specification is 18.85 +/- 0.1 mm.

Diameter measurements from a sample of shafts taken from each roughing lathe are displayed in a box and whisker plot in Figure 2.

Figure 2 Box and Whisker Plot Lathe Comparison Example
Where does the big m casino boat go. Blackjack club fruit machine.

Lathe 1 appears to be making good parts, and is centered in the tolerance.
Lathe 2 appears to have excess variation, and is making shafts below the minimum diameter.
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.
