A few new features Quality People might like

Gage R&R Study (Expanded)Include additional factors,analyze studies that are balanced or unbalanced, specify iffactors are fixed or random, and more.

Compare two capability analyses to see if the process has

improved. General RegressionEasily specify interaction and

polynomial terms, compute confidence intervals for regressioncoefficients, and more.

Export to PowerPoint and WordDirectly export your graphsand Session window output for easy reporting.

Nonlinear RegressionModel non-linear relationshipsbetween variables.

Power and Sample SizeUse seven new tools to calculatepower and sample size.

More power and sample size options

Minitab provides power, sample size, and difference (effect)calculations for the following procedures: one-sample Z

one-sample t

two-sample t

paired t one variance test

two variances test one-sample proportion

two-sample proportion

one-sample Poisson rate

two-sample Poisson rate

one-way analysis of variance two-level factorial designs Plackett-Burman designs

General Full Factorial designs

You can also estimate the sample size you need to obtain a specificmargin of error using Sample Size for Estimation.

A warning about using Minitab Assistant

Minitab has tried to make these platforms as simple and

easy to use as they could. In doing so, sometimes they

took a slightly different statistical approach than the

traditional one. So the p-values may not always match upexactly.
