Create Attribute Agreement Analysis Worksheet for Perform Attribute Agreement Study

Use Create Attribute Agreement Analysis Worksheet to generate a data collection worksheet for your specific attribute agreement analysis. Minitab requires a certain data organization so that your attribute agreement analysis is performed correctly.

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

Example

The default attribute agreement analysis worksheet contains rows for 300 runs. This includes 50 samples, 3 appraisers, and 2 replicates. The default values should be considered minimum values. You can increase the number of samples, appraisers, and replicates, however, using smaller numbers of samples and appraisers will hinder your assessment of repeatability and reproducibility.

In this worksheet, RunOrder lists the order in which the assessments should be made. Samples and Appraisers list which appraiser assesses which sample for each run. Appraiser A assesses sample 1 first, then assesses sample 28. By default, runs are randomized within appraisers, so Appraiser A assesses all the samples first, Appraiser B assesses them second, and Appraiser C assesses them third. All appraisers should assess all the samples before they start the second sequence of replicates. Assessment values may be recorded in C4.

Note

The data collection order in your worksheet will be different than the order in this worksheet, because the order for each worksheet is random. If you want to generate the same order more than one time, set the base of the random number generator.

C1	C2	C3-T
`RunOrder`	`Samples`	`Appraisers`
1	1	A
2	28	A
3	6	A
4	37	A
5	44	A
6	38	A
…	…	…

How-to

Choose Solutions Modules > Capabilities > Measurement System Analysis, then select Launch.
Under Attribute/Inspection Study, select Select an Attribute/Inspection Study.
Select Perform attribute agreement study, then click OK.
Select Create Attribute Agreement Analysis Worksheet, then click OK.
Specify whether you have standard values and how to represent them in the worksheet. From the dropdown list, select one of the following options.
- Sample standard/attribute unknown, select this option when you do not have standard values for each sample.
- Sample standard/attribute in text, select this option when you want to type text values into the dialog box to use for standard values for each sample.
- Sample standard/attribute in numeric values, select this option when you want to type numeric values into the dialog box to use for standard values for each sample.
- Sample standard/attribute in worksheet, select this option when you have a column of samples and a column of standard values in the worksheet. Because these columns specify the number of samples and the sample names, go to step 8.
In Number of samples, enter the number of samples in your study. You can have from 2 to 200 samples.
Under Sample Name, use the default sample numbers or type unique names to identify each sample. You can use text, numbers, or any combination of both. If you also have standard values, enter the standard values or the column that contains the standard values.
In Number of appraisers, enter the number of appraisers who measure samples. You can have as many as 50 appraisers.
Under Appraiser Name, use the default numeric identifiers or type unique names to identify each appraiser. You can use text, numbers, or any combination of both.
In Number of replicates, enter the number of times that you want to evaluate each sample. You can have as many as 50 replicates.
Click OK.
