We learn all these tests in the Minitab Training. We here discuss three methods of calculating process capability, viz., Defects Per Million Opportunities (DPMO), Process Capability Index – Corrected Process Capability Index (Cp & Cpk) and Standard Normal Approximation method. If our data fits satisfactorily with Normal curve model, then we use this model to calculate Process Capability. So, we check the Normality of our data to understand how much closer it is to the normal curve model.

We need to fit our data into a statistical model. And also we arrive at a sampling size and sampling methodology, do collect data, we screen the data for errors – trends and patterns, typo-errors, the stability of process to validate that collected data represent the process.

Hence, we use Measurement System Analysis to check the reliability of our data sources. We need to be doubly sure that our data is reliable. In this phase, the real world problem gets converted into a statistical problem which is easier to solve. In Measure Phase, the defined problems are measured in terms of statistics. In DMAIC methodology, the problem is defined in the first phase. Because Six Sigma is an investigative problem-solving methodology and Statistical Data Analysis is the backbone of Six Sigma. This Minitab Training is designed as per DMAIC structure of Six Sigma. Statistical Data Analysis: Minitab Training Statistics and DMAIC
Minitab t test how to#
Let’s understand how to conduct Statistical Data Analysis using Minitab effectively. Minitab provides a quick, effective solution for the level of analysis. It is also extensively used by Six Sigma Experts a is an important part of studying data, particularly in the Measure and Analyse phases of DMAIC.
Minitab t test software#
Minitab is a software package that helps us in the analysis of data. The Minitab Data Analysis program is structured on Six Sigma’s DMAIC framework. This program covers basic statisitical theories and tools along with Minitab tools and application. Minitab Training will help you understand statistics and data analysis and give you hands-on Minitab Software.
