Chapter 10 Key Terms
Single-Variable, Independent-Groups Designs
Below are the new key terms introduced in this chapter. It is
important to know the meanings of these terms because they will be
used in later discussion. You can get the meaning for any term from
the glossary by clicking on the term. However, we encourage you to
challenge yourself to generate the meaning before you look it up.
Such active learning is much more effective in building a mastery of
the material.
