Hypothesis testing


When solving problems and determining casual relationships, we want to test if our hypothesis is true or false. This course teach you how to do that.

Lean Tech offers virtual and physicial training:


Why learn hypothesis testing?


Have you ever made a change to improve a process and wanted to determine the effect?

Or compared data from different machines, shifts, departments, locations, etc. and been in doubt whether there are significant differences?

This training is for you!


Learning objectives


This training enables you to:

  • Develop hypothesis about causal relationship
  • Determine if datasets have significant different center or variation
  • Determine if an improvement made significant changes
  • Understand causal relationships using statistics

  • Develop hypothesis based on theories of causation
  • Practical and statistical significance
  • Statistics and probability
  • Hypothesis testing with continuous and discrete data
  • Type I and Type II errors
  • Decide which test to use
  • Decide if data sets have significantly different center or variance
  • Assess sampling strategy and sample size
  • Correlation and regression

Galton board

We use a Galton board to understand basic statistics, generate data and test if there are significant differences between datasets.

What does it take to make significant differences? How does sample size affect?

The Galton board provides a good visual understanding of histogram, normal distribution and probability.

We use SigmaXL (Add-in to excel) during training, unless otherwise agreed (Minitab and JMP are alternative solutions). You can download a 30 days free trial version before this course.
