Training & Education: Illustrations

FREE!
Dynamic illustrations (also known as simulators) allow your staff and colleagues to actively engage concepts by manipulating them and seeing how they respond. This activates learning and active learning leads to rapid application.

Each illustration is personalized – so please do not distribute them. Instead, ask others to visit this page and download a set for themselves.

Instructions on how to use illustrations
Look (see illustration above) for the “Download Instructions” button at the bottom of each illustration. When you click it, a PDF will download providing instructional details.

Some of the Topics Covered

» t distribution & hypothesis testing (t-tests 1/2 sided, p-values)

Many textbooks cover the t-test and t-distribution. We go further with this dynamic illustration. Engage the t-distribution by adjusting n, the sample size, as well as alpha.

Concepts taught include:

  • p-values and hypothesis tests (t-test)
  • t-values
  • z-scores
  • sample-size effect on t-distribution and t-tests
  • alpha, Type I errors
t_destribution 1
t_destribution 2
t_destribution 3
» confidence intervals for the mean and standard deviation (alpha, t, sample size, etc.)

Get a close look at confidence intervals for both mean and standard deviation.

Concepts taught include:

  • one and two-sided confidence intervals
  • effect of sample size and alpha on confidence intervals
  • intervals based on t, z and chi-square
  • Type I errors
Intervals 1
Intervals 2
Intervals 3
» capability analysis (Cp, Cpk, etc. Confidence Iintervals for Cp)

Capability analysis can be understood with this JMP-based dynamic illustration. Explore a variety of indices by adjusting the target, specifications – 1 and 2-sided, symmetrical / asymmetrical – and process variation. Position the mouse over the indices, sliders and other elements in the illustration to reveal explanatory.

Concepts taught include:

  • Cpk, Cp, Cpu, Cpl
  • distance to the nearest specification
  • defects, PPM, Yield
  • adjustable 1 and 2-sided specifications, symmetrical/asymmetrical
  • effects of process location, target and centeredness
  • effects of sigma
Capability Analysis 1
Capability Analysis 2
» oneway ANOVA & power

Concepts taught include:

  • Type I and Type II Errors
  • Power and Operating Characteristics Curves
  • Affects of alpha, n, s and delta on power
  • Interpreting p-values
  • Confidence Intervals
  • Hypothesis testing
  • t and F distributions
Anova 1
Anova 2
Anova 3

» equivalence tests (two, one-sided tests)

Any difference, no matter how small or how irrelevant, can be made to be statistically significant if enough data is collected. Equivalence tests get around this be incorporating a minimum, relevant difference that is to be considered significant.

Concepts taught include:

  • The effect of alpha, sample size and delta on equivalence.
  • Two, one-sided tests (TOST)
Equivalence 1
Equivalence 2

Minimum requirement for JMP 9

All dynamic illustrations now require JMP 9 or 10 from SAS Institute.
