Question

True or false Variables are those factors that can be changed in an experiment

Answer 1

The statement that variables are factors that can be changed in an experiment is true. Variables include independent variables that are manipulated by the researcher, dependent variables affected by the independents, and controlled variables that are kept constant.

Step-by-step explanation:

True or false: Variables are those factors that can be changed in an experiment. The statement is true. In the context of a scientific experiment, a variable is indeed any part of the experiment that can vary or change. There are different types of variables in an experiment:

• Independent variables: These are the variables that the researcher manipulates to observe their effect on the dependent variable.
• Dependent variables: Also known as the outcome variable, this is the factor that is affected by changes in the independent variable.
• Controlled variables: These are other possible variables that could affect the outcome, which are kept constant throughout the experiment in order to isolate the effect of the independent variable.

Experiments might also include a control group, which does not receive the experimental treatment, to compare against an experimental group that does. This allows scientists to make cause-and-effect claims more confidently.

Answer 2

True

Variables is changing. It is any factor, trait or condition that can exist in differing amounts or types. An experiment has three types: Independent, Dependent and Controlled.
