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”

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
