Heatmap for Perform Nested Study

Use Heatmap to visualize nested study results by multiple categorical variables.

In a nested study, each part is unique to the operator; no two operators measure the same part. This study is called nested because one or more factors is nested under another factor and, thus, not crossed with the other factors.

This example applies to the Measurement System Analysis Module. For more information, go to www.minitab.com/measurement-system-analysis-module.

Example

In this worksheet, Measurement is the graph variable, thickness of glass. Operator is the row variable. Sand Supplier, Furnace, and Plant are the column variables.

C1	C2	C3-T	C4-T	C5-T	C6-T
`Part`	`Measurement`	`Operator`	`Sand Supplier`	`Furnace`	`Plant`
5	5.2	A	Best Silica	Tank	East
4	5.3	A	Quality Compounds	Tank	West
7	5.7	A	Natural Sands	Pot	South
7	5.6	A	Natural Sands	Pot	South
2	5.2	B	Best Silica	Tank	East

How-to

Choose Solutions Modules > Functions > Customer Contact Center KPIs, then select Launch.
Under Destructive Gage R&R Study, select Select a Destructive Gage R&R Study.
Select Perform nested study, then click OK.
Select Heatmap, then click OK.
From Display, select Function of a variable.
In Graph variables enter the column that contains the measurement data.
From Function, select the function of the measurement. For example, if you select Mean, the color gradient of the rectangles in the heatmap uses the mean value of the measurement value in each rectangle.
Note
The mean is the often used to evaluate the factors that influence the measurement system.
In Row variables enter up to five columns that define the rows.
In Column variables enter up to five columns that define the columns.
Click OK.
