A controlled variable in a flame test is a factor that is kept constant throughout the experiment to ensure that any observed changes in the flame color are due to the independent variable being tested. Examples of controlled variables in a flame test may include the type of metal salt being tested, the type of burner being used, the distance between the flame and the sample, and the duration of heating. By controlling these variables, researchers can accurately determine the effect of the independent variable on the flame color produced.

What is the one variable that is purposely changed to test a hypothesis called?
The variable that is purposely changed to test a hypothesis is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable, which is the outcome being measured.
Why must the size of the test flame be kept very small?
Keeping the test flame size small ensures consistent and controlled conditions for conducting the test. A small flame also helps in observing the characteristics of the substance being tested more accurately and allows for better comparison with known standards. Additionally, a small test flame minimizes safety risks and potential variability in results.
What type of variable depends on the controlled variable?
The variable that depends on the controlled variable is typically the dependent variable. This variable is measured or observed to see how it responds to changes in the controlled variable during an experiment or study.
What is the factor that you can change to test a hypothesis?
The factor that you can change to test a hypothesis is called the independent variable. It is the variable that is manipulated or controlled by the researcher to observe its effect on the dependent variable, which is the outcome being measured in the experiment.
What is the controlled variable of the stroop effect?
The controlled variable of the Stroop effect is typically the list of words that participants are asked to read during the test. This list is controlled to ensure consistency in the stimuli presented to all participants, helping to isolate the effect of interference in the task.

What is the one variable that is purposely changed to test a hypothesis called?
The variable that is purposely changed to test a hypothesis is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable, which is the outcome being measured.
What is another name for the test variable?
Another name for the test variable is the "independent variable." This variable is manipulated or controlled in an experiment to observe its effects on other variables, typically the dependent variable. In some contexts, it may also be referred to as the predictor variable.
Which variable is the one variable that is purposley changed to test a hypothesis?
The independent variable is the one that is purposely changed to test a hypothesis.There are 3 kinds of variables in a scientific experiment: independent, dependent, and controlled.
What is cotrols variable?
controlled variable is something that is controlled by the independent variable
How do you use control variable in a sentence?
Most of scientific experiments use controlled variable to evaluate the result.controlled variable allows us many benefits over traditional variables.Double blind studies often use controlled variables & pseudo Drugs.
What is a controlled variable in a science fair project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
