Experimental variables include independent variables, which are manipulated by the researcher to observe their effect, and dependent variables, which are measured as the outcome of the experiment. For example, in a study on plant growth, the amount of sunlight (independent variable) can be varied, while the growth rate of the plants (dependent variable) is recorded. Other examples include control variables, which are kept constant to ensure a fair test, such as soil type and water amount.
What else can I help you with?
What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
What type of a variable is an experimental controls?
independent variable
What is experimental Variable?
The independent variable is the one variable that you change in your experiment
What type of variable is an experimental control?
Independent variable
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is a synonym for experimental variable?
Variable

What is the experimental variable?

independent variable

What type of variable is an experimental control?
Independent variable
What is the variable that the scientist changes in an experiment?
experimental variable
What type variable is an experimental control?
Independent variable
What is the experimental variable and what is the dependent variable?
the experimental variable is like the independent variable, which is the only thing you can change in a science experiment, and the dependent variables are the things that stay the same.
What is the difference between the independent variable and the experimental variable?
the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between experimental variable and a control variable?
