A multiple stimulus with replacement is best described by which of the following options below? A) Many stimuli are presented simultaneously, but only one choice is allowed at a time. After an item is chosen, it is returned to the array on subsequent trials. B) Stimuli are presented in pairs, and one choice is allowed at a time. All stimuli are matched together at least once.

Completely Randomized Design correct answer: An experimental design where all experimental units are randomly assigned treatments. Randomized Block Design correct answer: An experimental design in which the experimental units are placed into homogeneous groups. The random assignment of the units to the treatments is carried out separately within each block. Matched Pairs Design correct answer: An experimental design in which each subject receives both treatments in a random order or sub...

Internal Validity refers to how well an experiment is done, especially whether it avoids confounding (more than one possible independent variable [cause] acting at the same time). The less chance for confounding in a study, the higher its internal validity is. Covariance Manipulating an IV which has at least 2 levels, enables researchers to ask "compared to what?" Is the independent variable related to the dependent variable? Temporal precedence Manipulate IV, measure DV, the cause variable ...
