## Process Capability with Minitab

What is Process Capability? Process capability measures how well the process performs to meet given specified outcome. It indicates the conformance of a process to meet given requirements or specifications. Capability analysis helps to better understand the performance of the process with respect to meeting customer’s specifications and identify the process improvement opportunities. Process Capability […]

## Attribute MSA with JMP

Use JMP to Implement an Attribute MSA Data File: “AttributeMSA.jmp” Steps in JMP to run an attribute MSA: Click Analyze -> Quality & Process ->Variability/Attribute Gauge Chart Select “Appraiser A”, “Appraiser B” and “Appraiser C” as “Y, Response” Select “Part” as “X,Grouping” Select “Reference” as “Standard” Select “Attribute” as the “Chart Type” Click “OK” Click on […]

## Attribute MSA with SigmaXL

Use SigmaXL to Implement an Attribute MSA Data File: “Attribute MSA” tab in “Sample Data.xlsx” (an example in the AIAG MSA Reference Manual, 3rd Edition). Step 1: Reorganize the original data into four new columns (i.e., Appraiser, Assessed Result, Part, and Reference). Select the entire range of the original data (“Part”, “Reference”, “Appraiser A”, “Appraiser […]

## Variable Gage R&R with SigmaXL

Variable Gage R&R Variable Gage Repeatability & Reproducibility (Gage R&R) is a method used to analyze the variability of a measurement system by partitioning the variation of the measurements using ANOVA (Analysis of Variance). Whenever something is measured repeatedly or by different people or processes, the results of the measurements will vary. Variation comes from […]

## Variable Gage R&R with Minitab

What is Variable Gage R&R? Whenever something is measured repeatedly or by different people or processes, the results of the measurements will vary. Variation comes from two primary sources: We can use a variable Gage R&R to conduct a measurement system analysis to determine what portion of the variability comes from the parts and what […]

## Run Chart with SigmaXL

Why we use a Run Chart A run chart is a chart used to present data in time order. These charts capture process performance over time. The X axis indicates time and the Y axis shows the observed values. A run chart is similar to a scatter plot in that it shows the relationship between X and […]

## Scatter Plot with SigmaXL

What is a Scatter Plot A scatter plot is a diagram to present the relationship between two variables of a data set. It consists of a set of data points set on two axis. On the scatter plot, a single observation is presented by a data point with its horizontal position equal to the value of […]

## Histogram Rendering with SigmaXL

What is a Histogram? A histogram is a graphical tool to present the distribution of the data. These plots are used to better understand how values occur in a given set of data. The X axis represents the possible values of the variable and the Y axis represents the frequency of the value occurring. This graphical […]

## Histogram Rendering with Minitab

What is a Histogram? A histogram is a graphical tool to present the distribution of the data. The X axis represents the possible values of the variable and the Y axis represents the frequency of the value occurring. This graphical summary consists of adjacent rectangles erected over intervals with heights equal to the frequency density of […]

## Box Plot with SigmaXL

What is a Box Plot? In statistics, graphical analysis is a method to visualize the quantitative data. Graphical analysis is used to discover structure and patterns in the data. The presence of which may explain or suggest reasons for additional analysis or consideration. A complete statistical analysis includes both quantitative analysis and graphical analysis. When […]

## Box Plot with Minitab

What is a Box Plot? A box plot is a graphical method to summarize a data set by visualizing the minimum value, 25th percentile, median, 75th percentile, the maximum value, and potential outliers. A percentile is the value below which a certain percentage of data fall. For example, if 75% of the observations have values […]
