Results. The 3 operators measure each of the 15 electrodes two times, for a total of 90 measurements. The run order lists the order in which the measurements should be taken.

Calculate the differences and then perform a 1-Sample Wilcoxon test on the differences.

Minitab's make patterned data capability can be helpful when entering numeric factor levels. For example, to enter the level values for a three-way crossed design with a, b, and c (a, b, and c represent numbers) levels of factors A, B, C, and n observations per cell, Make Patterned Data 3 times, one time for each factor, as shown:

Use Nonparametric Distribution Analysis (Arbitrary Censoring) to estimate the reliability of a product when you have arbitrarily-censored data and no distribution fits your data. Arbitrarily-censored data include left-censored observations and/or interval-censored observations. For more information, go to Data censoring.

Proceed with the analysis if the sample is large enough. Although many hypothesis tests are formally based on the assumption of normality, you can still obtain good results with nonnormal data if your sample is large enough.

For a 3-factor ANOVA with all fixed factors, these formulas are the F-statistics when the model is full. Formulas. For F(A), the degrees of freedom for the numerator are a - 1 and for the denominator are (n - 1)abc.

Use Outlier Test to identify a single outlier in a sample.. For example, a quality engineer performs an outlier test to determine whether a value in the sample that seems unusually small is an outlier.

Use a binomial distribution to represent data that consists of the number or proportion of observations that have a particular attribute. Data include samples of equal size (n) from k populations.
