Question
What does an experiment need to have in order for it to be a true experiment? Group of answer choicesA manipulated variable Random assignment A confounding variable Both A and B
Solution
A true experiment needs to have both A and B. This means it needs to have a manipulated variable, which is also known as the independent variable that the experimenter changes to see its impact, and random assignment, which ensures that each participant has an equal chance of being placed in any group in the experiment. This helps to ensure that the experiment measures the effect of the independent variable accurately without being influenced by other variables. A confounding variable, on the other hand, is something that should be avoided in a true experiment as it can interfere with the results and lead to incorrect conclusions.
