Multi Vari Analysis with SigmaXL
Learning Multi-Vari Analysis with SigmaXL Multi Vari Analysis with SigmaXL is a graphic-driven method to analyze the effects of categorical inputs on a continuous output. It studies how the variation in the output changes across different inputs and helps us quantitatively determine the major source of variability in the output. Multi Vari charts are used…
Read MoreRun Chart with SigmaXL
Why we use a Run Chart with SigmaXL A run chart with SigmaXL 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…
Read MoreCapability Analysis with SigmaXL
Understanding Process Capability with SigmaXL Process capability with SigmaXL 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…
Read MoreBox Plot with SigmaXL
What is a Box Plot with SigmaXL? In statistics, graphical analysis is a method to visualize 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.…
Read MoreHistogram Rendering with SigmaXL
What is Histogram Rendering with SigmaXL? Histogram rendering with SigmXL provides 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…
Read MoreCentral Limit Theorem with JMP
What is Central Limit Theorem? The Central Limit Theorem is one of the fundamental theorems of probability theory. It states a condition under which the mean of a large number of independent and identically-distributed random variables, each of which has a finite mean and variance, would be approximately normally distributed. Let us assume Y1, Y2…
Read MoreVariable Gage R&R with SigmaXL
Learning Variable Gage R&R with SigmaXL Variable Gage R&R with SigmaXL (Gage Repeatability &Reproducibility) 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…

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…
Read MoreScatter Plot Using SigmaXL
Producing a Scatter Plot Using SigmaXL A scatter plot using SigmaXL creates 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…

Read MoreBox Plot with JMP
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…

What is a Histogram? A histogram is a graphical tool to present the distribution of the data. The X axis of a histogram represents the possible values of the variable and the Y axis represents the frequency of the value occurring. A histogram consists of adjacent rectangles erected over intervals with heights equal to the…
Read MorePareto Analysis with SigmaXL
The Pareto Principle and Pareto Analysis with SigmaXL The Pareto principle is an observation not a law. Named after Italian economist Vilfredo Pareto, this principle states that for a variety of situations, 80% of consequences come from 20% of the causes, thus the Pareto principle is also known as the 80/20 rule. The 80/20 rule…
