THE SCIENTIFIC METHOD AND DESCRIPTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The thing that the researcher deliberately changes or manipulates in an experiment is called the
A
Dependent Variable
B
Extraneous Variable
C
Random Variable
D
Independent Variable
Explanation: 

Detailed explanation-1: -The manipulated variable, also known as the independent variable, is the factor or condition that is purposely changed by the scientist. It is what is being tested, or the cause of a cause and effect relationship.

Detailed explanation-2: -A manipulated variable, also known as an independent variable, is a part of an experiment that you can change to see how other variables respond. Here are the three types of variables in an experiment: Manipulated variable: The variable that you control and change based on the experiment.

Detailed explanation-3: -An independent variable is the variable you manipulate or vary in an experimental study to explore its effects. It’s called “independent” because it’s not influenced by any other variables in the study.

Detailed explanation-4: -Manipulation of the Independent Variable Again, to manipulate an independent variable means to change its level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.

Detailed explanation-5: -Therefore, in experiments, a researcher manipulates an independent variable to determine if it causes a change in the dependent variable. As we learned earlier in a descriptive study, variables are not manipulated. They are observed as they naturally occur and then associations between variables are studied.
