Introduction

Statistical Thinking and it concepts are methodologies that uses data and statistics to make informed decisions and improve business processes. It is based on three key principles:

All work consists of interconnected processes. Every activity in a business can be broken down into a series of steps, and these steps are often interrelated. By understanding these relationships, we can identify areas for improvement.
All processes have variation. No process is perfect, and there will always be some variation in the results. This variation can be caused by many factors, such as chance, errors, and changes in the environment.
Variation can be reduced. By understanding the causes of variation, we can take steps to reduce it and improve the consistency of our processes.

Statistical Thinking Concepts

Flowcharts: Ideal for visually mapping out process steps.
Check Sheets: Collect data, spot variation & its causes.
Cause & Effect Diagrams: Brainstorm, organize, find variation causes.
Pareto Chart: Prioritize & focus your efforts effectively.
Histograms: See variation & pinpoint causes at a glance.
Scatter Plots: See how inputs impact outputs & find variation causes.
Stratification: Analyze variation across platforms, machines, or shifts.
Run/Control Charts: Track variation over time, spot causes (special/common), avoid tinkering.
Capability Ratios: Track variation against targets for improvement.
Five Whys: Dig deep to find variations' root.
Linear Regression: Find relationships between inputs & variation.
Designed Experiments: Test & pinpoint variation triggers.
