Question
In an experiment, which of the following statements is true about the dependent variable?Multiple ChoiceIt is under the experimenter's control and remains constant.It is decided by the researcher based on chance alone.It is measured by the researcher and is expected to change.It is randomized across different experimental groups.
Solution
The correct statement about the dependent variable in an experiment is: "It is measured by the researcher and is expected to change."
Here's why:
In an experiment, the dependent variable is the outcome that the researcher is interested in measuring or observing. It's called "dependent" because its value depends on the changes or manipulations made to another variable known as the independent variable.
The independent variable is under the experimenter's control and is manipulated to observe its effect on the dependent variable. The dependent variable is not constant and is expected to change based on the manipulations of the independent variable.
The dependent variable is not decided by chance alone nor is it randomized across different experimental groups. These statements are incorrect.
Therefore, the correct answer is "It is measured by the researcher and is expected to change."
