| When
data are taken and statistically analyzed there are tests that can
be performed to determine the validity of the data and whether operational
characteristics have varied beyond reasonable limits. Those tests
determine whether the process has changed, whether the population
characteristics have shifted, whether the population is homogeneous
or is a mixture.
In this course you will learn how to perform and interpret the results
of:
- Z-tests
- T-tests
- Chi-square tests
- F-tests
You will learn how to interpret and apply:
- Sample size selection
- Consumer and producer sampling risks
- Confidence intervals
- Predictions
