The test variable (independent variable) and the outcome variable (dependent variable) are both critical factors in an experiment. To understand an experiment, you must be able to tell the difference between these variables.Select the statement below that accurately differentiates between the test variable (independent variable) and the outcome variable (dependent variable).The test variable is purposely changed in an experiment and the outcome variable always stays constant.The test variable is changed by the experimenter and is independent of other variables. The outcome variable changes because of the test variable and is observed and measured.The test variable must be constant in order for the outcome variable to be controlled.The test variable is measured because the outcome variable is being tested.

Which of the following accurately summarizes a test variable (independent variable) in an experiment?A constant variable that is not changed by the experimenter.A statement that gives you information about the control variable.A variable that is changed in the experiment on purpose by the experimenter.A variable that is measured in the experiment.

In experimental research the dependent variable  is the condition that you measure in an experiment.Group of answer choicesTrueFalse

Scientists observe the world around them and use the scientific method to study it. They do research and form a hypothesis to start their experiment. Every experiment must have a test variable and an outcome variable. The test variable is the factor that is to see what the results are in the experiment. The test variable is also called a(n) because it is not affected by other variables. The outcome variable is what is being in the experiment. The outcome variable is by the scientist.dependent variableobserved and recordedindependent variablecreatedpurposely changedcontrolled and recordedmeasuredstay the same

Select the statement that accurately summarizes an outcome variable (dependent variable) in an experiment.A variable that is changed by the experimenter.A variable that keeps everything constant.A variable that you create to change.A variable that is measured in the experiment.

In experimental research, the independent variable is manipulated or changed by the experimenter to measure the effect of this change on the dependent variable.  Group of answer choicesTrueFalse
