Making Data Analysis Even Easier
► Over the years, customers have told us:
“I don’t know which tool to use”
“Minitab has too many options”
“The dialogs are too
technical”
“I need help interpreting my results”
© 2013 Minitab, Inc.
Designed for Green/Black Belts, occasional users, and those
who are new to statistics or Minitab

Assistant for DOE
► DOE easier than ever► Most requested Assistant feature
2
6-15 factors
2-5 factors
© 2013 Minitab, Inc.
What value does it provide?
►Customers are already using DOE in core Minitab
►However, users really struggle with DOE:• Choosing the appropriate design
• Analyzing the data is not always straightforward
►Easier for our users to:• Plan and create experiments• Analyze the data• Conduct residuals analysis• Find optimal settings

Assistant for Multiple Regression
© 2013 Minitab, Inc.
What value does it provide?
►Regression is used everywhere
►Customers liked Minitab 16 Assistant, but only for 1X
►Easier for our users to:• Find significant factors• Conduct residuals analysis• Identify outliers• Find optimal settings

Improved Graphical Analysis
Easier Dialogs + More Extensive Output
© 2013 Minitab, Inc.
What value does it provide?
►Better dialogs – e.g. shows categorical samples
►Diagnostic reports with guidance
►Report card with next steps

Top EnhancementsRegression & GLM
© 2013 Minitab, Inc.
© 2013 Minitab, Inc.
What value does it provide?
►CONSISTENCY across regression and GLM
►Better workflow (e.g. stepwise > model fitting), plus new model dialog and “view model”
►More statistical features:• Automatic model selection• Prediction• And more!
►More graphical features• Factorial, contour and surface plots plus response optimizer

DOE dialog changes• Alpha moved from Graphs to Options, called “Confidence level”
• Box-Cox for Factorial and RS
• Effects, main effects and interaction plots display all terms, includes excluded terms
• Cube plots of fitted values available for reduced models
• Response optimizer changes:– Factorial allows for constraints– Doesn’t require min/max value– Only displays composite desirability for >1 X– Provides CI and PI tables
