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”

Designed for Green/Black Belts, occasional users, and those

who are new to statistics or Minitab

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

October 22, 201410

© 2014 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
