The Session window not only looks better, but it also includes several great enhancements, including the ability to:

Easily manage your data within the Project Manager using new options for sorting your worksheets by title or in chronological order.

Identify which inputs affect your outputs with this new type of DOE screening design. These designs can provide
an alternative to standard screening designs where main effects are confounded with two-way interactions.

Calculate statistical tolerance intervals for nonnormal data using a wide variety of distributions
including Weibull, lognormal, exponential, and more.

Explore relationships between variables, run multiple comparisons, and calculate predictions for mixed
models.
Visually identify significant X’s with effects plots for general factorial and response surface designs.
Incorporate a user-specified process (historical) standard deviation in relevant calculations.
Include both your factors and covariates when using the response optimizer to find optimal settings.
Enter commands to expand Minitab’s functionality using a docked pane that keeps commands separate
from Session output.
Import Session output into Word and Excel in table format to easily manipulate and customize the
appearance of your results.
