Answer to Question 1

A

Answer to Question 2

A
Feedback:
Various external factors, such as the research environment, can affect outcomes. In carefully controlled quantitative research, steps are taken to minimize situational contaminants (i.e., to achieve constancy of conditions) so that researchers can be confident that outcomes reflect the influence of the independent variable and not the study context. Collecting data at the same time every day is an example of this. A crossover design involves exposing people to more than one treatment. Such designs are inappropriate for certain research questions, however, because of possible carryover effects. External validity concerns inferences about whether relationships found for study participants might hold true for different people, conditions, and settings. These other answers do not enhance constancy of conditions.
