With nearly 50 enhancements that increase Minitab’s functionality and make it easier to use, Minitab 15 has something for everyone. And the benefits are immediate – minimal changes to the interface allow you and your teams to access these improvements without having to re-learn the software or update your training and support materials.

 

Assign a Formula to a Column or Stored Constant; Columns Update When Data in the Worksheets Change

One of our most frequently requested features, linking formulas to columns or constants not only saves time, but also makes Minitab even easier for users who are accustomed to using spreadsheet software.

Multiple Undo/Redo in Data Window

Undo mistakes and redo changes in the Data window. In prior releases, you could undo/redo one step back. In Minitab 15 you can undo/redo many steps back.

Enhanced Calculations Capabilities

Minitab 15 includes more than 40 new calculator functions, including 23 for manipulating text. New workday, weekend, and holiday designations help you with elapsed time calculations. Percentiles and the geometric mean can now be calculated as well.

Suppose you have a column of start dates and a column of end dates. You can use the Calculator to compute the number of elapsed business days (excluding weekends and holidays).

Suppose you have imported employee names from a database that are formatted LASTNAME FIRSTNAME, but you only need the employees' last names. You can use the Calculator to extract the last names and place them in a new column.

New Currency and Percentage Formats for Data

Minitab now displays currency and percentage symbols on data in the Data window, on graphs, and output tables.

Password Protection for Project Files

Password protect Minitab project files for added security, or simply to prevent important information from being accidentally altered.

Power (OC) Curves for Power and Sample Size

New graphs help you examine the prospective sample space and choose the optimal sample size, with the desired power and detection goal.

Easily Generate Your Gage R&R Worksheet

Generate a data collection worksheet based on your specific Gage R&R study.

Type 1 Gage Study

Evaluate the bias, repeatability, and capability of your measurement system on a single part.

Gage R&R: Probability of a False Answer

Examine the probability of passing a defective product (consumer’s risk) or of failing a good product (producer’s risk).

Acceptance Sampling

Use this new method to help answer the question, "How many units should I test before deciding whether to accept or reject delivered materials?" You can use Acceptance Sampling with either attributes or variables data.

Optimal General Factorial Designs

Select an optimal design to reduce the number of experimental runs in a general full factorial design, or to evaluate or improve optimality of an existing general factorial design.

Probability Distribution Plot

View the shape of a distribution, visually compare two distributions, or display the shapes of a distribution with varying parameters. In addition, you can view the area under a distribution curve that corresponds to either a given probability or x value. This new plot is a useful visualization tool for teaching as well as for applied analysis.
