7. Product and Process Comparisons

7.4.2. Are the means equal?

7.4.2.5.

Confidence intervals for the difference of treatment means

Confidence intervals can easily be put around the difference between two means
 
 
 
 
 
 
 

 

This page shows how to construct a confidence interval
around (m_i - m_j) for the one-way ANOVA by continuing an  example shown on a previous page. 

Later on the topic of estimating more general linear combinations of means (primarily contrasts) will be discussed, including how to put confidence bounds around contrasts.
