• Normality Test to identify whether data follows a Normal Distribution or not?

• Individual Distribution Identification to identify whether the data follows a normal distribution, or can it be transformed into the normal distribution?

• Detailed Interpretation of results for Graph Window including process Mean with respect to Target, Ppk value, how to read capability analysis graph, PPM i.e. Expected Overall Performance and Conclusion.

Hello Friends,

            Many times, when we go for the analysis, the first question that comes to our mind is about the type of data and which distribution is the best fit for the data. This is an important step before going for an analysis.

            If we select an incorrect option for the analysis, then the interpretation of the results will be incorrect, which in turn initiates incorrect action and thereby incorrect results.

            To avoid this from now onwards, we going to learn Individual Distribution Identification to identify the best distribution or transformation for your data before you perform an analysis in Minitab software with the help of a practical example for easy understanding and better clarity.

            This video consists of the following topics:

• Introduction of Individual Distribution Identification in Minitab

• Hypotheses for Individual Distribution Identification

• Data considerations for Individual Distribution Identification

• Example of Individual Distribution Identification

• Conduct Individual Distribution Identification in Minitab with a practical example to find out the most suitable distribution from 14 distributions and 2 transformations

• Detailed interpretation of results from Individual Distribution Identification including:

                  1. Probability plot for each distribution and transformation

                  2. The goodness of Fit Test with p-value and LRT p values for each distribution and transformation

                  3. Descriptive Statistics for all observations in the data set

                  4. Maximum Likelihood (ML) estimates to understand the specific distribution model that is used for your data

                  5. Impact of transformation (Box-Cox and Johnson) on the data set and

• The conclusion from the Individual Distribution Identification.

Hello Friends,

In this video, we are going to learn advance concepts or tools in capability analysis for continuous data i.e. Capability Sixpack. In Capability Sixpack, there are 3 types of analysis:

1) Normal Capability Sixpack

2) Between/Within Capability Sixpack and

3) Nonnormal Capability Sixpack

            As the procedure to conduct this analysis and interpretations of them are the same, we will learn only 1st type of it i.e. “Normal Capability Sixpack” in this video.

            The differences in other types are only the distribution of data or extent of variation in subgroups, same as that of seen in the previous videos on “Between/Within Capability analysis” and “Nonnormal Capability analysis”.

This video consists of the following topics:

• Introduction to Normal Capability Sixpack

• Data considerations for Normal Capability Sixpack

• Normal Capability Sixpack with Practical Example in Minitab

• The detailed stepwise procedure with a screenshot to understand how to conduct Normal Capability Sixpack in Minitab

• Detailed Interpretation of results in Graph Window including Xbar and R-Chart, the Last 20 subgroups plot, Normal Probability Plot, Capability Histogram and Capability plot with Cpk, Ppk and Cpm values, how to interpret Capability Sixpack graph and Conclusion.
