Applied Statistics for Six Sigma
A hands-on deep dive into the statistics behind Six Sigma. Participants learn which data and metrics matter in DMAIC projects, how to describe and test process data, and how to separate common-cause from special-cause variation using Minitab, so that improvement decisions rest on evidence rather than opinion.

- 3 days
Who it's for
- Green/Black Belts and anyone seeking advanced Six Sigma statistics
Learning objectives
- Use statistical tools within DMAIC projects
- Select the appropriate test and interpret results
- Characterise processes and identify common- cause variation
Detailed content
- Why measure: decisions, variation and the cost of guessing
- Types of data: continuous, discrete, attribute, ordinal
- Operational definitions and data-collection plans
- Sampling strategies: random, stratified, systematic, rational subgroups
- Performance metrics: DPU, DPMO, yield, rolled throughput yield, sigma level
- Central tendency: mean, median, mode and when each misleads
- Spread: range, variance, standard deviation, IQR
- Graphical analysis: histogram, box plot, dot plot, run chart, Pareto
- Shape: skewness, kurtosis, outliers and data stratification
- Probability basics and rules
- Normal distribution and the empirical rule
- Z-scores and areas under the curve
- Binomial and Poisson for defects and defectives
- Normality tests (Anderson-Darling) and transformations
- Sampling distributions and the Central Limit Theorem
- Confidence intervals for means and proportions
- Sample-size determination for a target precision
- Hypothesis testing logic: null, alternative, alpha, beta, power
- t-tests, paired t, ANOVA and chi-square: choosing the right test
- Common-cause vs special-cause variation
- Control charts: I-MR, X-bar/R, p and u
- Process capability: Cp, Cpk, Pp, Ppk and sigma level
- Correlation and simple regression for process drivers
- Minitab and Excel lab: complete characterisation of a real process

What participants say
“When I started the course I was a quality specialist; after it I was promoted to quality team leader. Six Sigma changed a lot for me. Very comprehensive – I'd suggest it 100%.”
“The course teaches you to take hold of a problem logically and solve it scientifically. The explanation was simple, and this way of thinking matters for life as a whole.”
“What I gained most: I never imagined how much money projects can lose. We ran a small cost project on our site and found mistakes we can now avoid.”
Frequently asked questions
How long is Applied Statistics for Six Sigma?
The program runs 3 days. In-company versions can be adapted to your needs.
Is the course taught in Arabic or English?
Sessions are usually delivered in Arabic with English technical terms and materials. Full English delivery is available for in-company groups.
Can you run it inside our company?
Yes. In-company programs use exercises built on your own processes. Tell us the group size and preferred timing and we will send a proposal.
Will I receive a certificate?
Participants who complete the program and its assessment receive a certificate from The Excellence Center, which can be verified online.
