The Scientific Method And Experiments Quiz

Guessing is not a part of the scientific method because it is based on speculation or intuition rather than systematic observation and experimentation. The scientific method involves making observations, formulating a hypothesis, conducting experiments to test the hypothesis, analyzing the data, and drawing conclusions based on the evidence. Guessing does not follow this systematic approach and lacks the rigor and objectivity required in scientific inquiry.

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 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.

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.

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.
