The House of Quality, or Quality Function Deployment (QFD), is a useful tool that Six Sigma Black Belt practitioners use during the Define phase of the DMAIC cycle of Six Sigma projects. The topic can be briefly discussed in Green Belt training or sometimes on online free Six Sigma courses. However, the House of Quality […]

### How to Calculate Probability Using the Poisson Distribution?

Lean Six Sigma Green Belt course graduates deal with two types of data during the Six Sigma Measure phase of their Six Sigma DMAIC projects: continuous data and discrete data. The Poisson distribution is a probability distribution for discrete data which takes on the values which are X = 0, 1, 2, 3 and so […]

### 4 Types of Relative Measures of Dispersion for Six Sigma

The Six Sigma approach is data-driven. Therefore, Six Sigma practitioners who have got the Lean Six Sigma training or another Lean Six Sigma Green Belt course will know that Six Sigma teams are confronted with many different types of data in different units of measure. Relative measures of dispersion are measures of the variance of […]

### 4 Absolute Measures of Dispersion You Need to Know

In the Measure phase of the DMAIC process in Six Sigma, there are many types of statistical parameters that graduates of Lean Six Sigma Green Belt training or other Online Six Sigma courses should know, including absolute measures of dispersion. Measures of Central Tendency serves to locate the center of the distribution. However, they do […]

### Measures of Central Tendency: Mean, Median & Mode

Statistics. While others might stifle a yawn at the mere word, Six Sigma practitioners who have passed the Lean Six Sigma Green Belt course knows that without statistics, no Six Sigma project will succeed. Statistics is simply part of the data-driven Six Sigma approach. At the Six Sigma Green Belt level, we need to have […]
