What is the purpose of carrying out an experiment?

To test your hypothesis.
To learn more about the world around you.
To prove you're smarter than your friends.
A and B
A, B, and C

Correct Answer

A. A and B

Explanation

The purpose of carrying out an experiment is to test your hypothesis and to learn more about the world around you. By conducting experiments, you can gather data and evidence to support or refute your hypothesis, allowing you to gain a deeper understanding of the topic you are studying. Additionally, experiments help to expand knowledge and contribute to scientific advancements.

What is experimental control?

A variable in the experiment.
Controlling one of the variables in the experiment to compare with the results of the noncontrolled group.
Similar to a hypothesis.
The variable that is manipulated for the experiment.

Correct Answer

A. Controlling one of the variables in the experiment to compare with the results of the noncontrolled group.

Explanation

Experimental control refers to the process of controlling one variable in an experiment while keeping all other variables constant. By doing so, researchers can compare the results of the controlled group with the non-controlled group, allowing them to determine the specific effect of the manipulated variable. This helps in establishing a cause-and-effect relationship between the manipulated variable and the observed outcome. Experimental control is an essential aspect of scientific experiments as it helps ensure accurate and reliable results.

The variable is what changes when the variable changes (seprate answers by a space or comma).

Correct Answer
dependent, independent
dependent independent
dependent,independent

Explanation
The question is asking for the variable that changes when the other variable changes. The correct answer is "dependent, independent" because the dependent variable changes in response to changes in the independent variable. The repetition of "dependent, independent" and "dependent,independent" in the answer is likely a mistake or redundancy.

5.

The variable changes are directly caused by the experimenter.

Correct Answer
Independent

Explanation
The given correct answer is "Independent". This suggests that the variable changes are directly caused by the experimenter. In an experiment, the independent variable is the one that is deliberately manipulated or changed by the researcher to observe its effect on the dependent variable. Therefore, the experimenter has control over the independent variable and can directly cause changes in it, leading to changes in the dependent variable.
