A general principle to follow when designing an experiment is to Blank______.Multiple choice question.increase the number of confounding variablesincrease the number of matching variablesmake the manipulation as strong as possiblemake the manipulation as complex as possible
Solution
The correct answer is "make the manipulation as strong as possible".
When designing an experiment, it's important to make the manipulation as strong as possible to ensure that the changes in the dependent variable are indeed caused by the manipulation of the independent variable. This helps to establish a clear cause-and-effect relationship.
Increasing the number of confounding variables would make it harder to determine which variable is causing the observed effect. Increasing the number of matching variables is not necessarily beneficial and could complicate the experiment. Making the manipulation as complex as possible could confuse participants and lead to unreliable results.
