Question
Which of the following are crucial characteristics of an experiment?Multiple select question.Ability to examine associationsAbility to observe phenomena in a natural settingRandom assignment of participants to conditionsManipulated independent variable
Solution
The crucial characteristics of an experiment are:
-
Random assignment of participants to conditions: This ensures that each participant has an equal chance of being placed in any group in the experiment. It helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment.
-
Manipulated independent variable: In an experiment, the researcher manipulates at least one variable to measure the effect on another variable. This manipulated variable is the independent variable. The ability to control and manipulate the variables in the experiment is a crucial characteristic of an experiment.
While the ability to examine associations and observe phenomena in a natural setting can be important in research, they are not specific to experiments and are more associated with observational or correlational studies.
