What are the three 3 basic variables used in an experiment?
An experiment usually has three kinds of variables: independent, dependent, and controlled.
How do we identify the 3 variables in an experiment?
- Independent Variable = What the investigator manipulates; the particular treatment or condition the.
- Dependent Variable = What is measured or observed; the “data” collected in the experiment.
- Control Group = Those participants treated just like the experimental group EXCEPT they are not.
What variables can be controlled in an experiment?
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.
How do you identify independent dependent and control variables?
Identify the variables
- Independent variable – the variable that is altered during a scientific experiment.
- Dependent variable – the variable being tested or measured during a scientific experiment.
- Controlled variable – a variable that is kept the same during a scientific experiment.
How are variables used in a science experiment?
You’ll find different variables in all types of subjects. But, the most common variables found in a science experiment include dependent, independent, and controlled. Check out what each is through examples. In an experiment, you need some type of control. Being able to modify a variable is important to study the effects.

Which is a control variable in a plant experiment?
In your plant experiment, the temperature is a control variable. When testing the growth in soil, make sure to keep all the plants at a consistent temperature. Without a constant temperature, you wouldn’t be sure if it was the temperature or soil making the plant grow better.
Which is a control variable in a diaper experiment?
The control variable in the diaper experiment could be the size of the diaper you use. When testing how much water the different brands can hold, you’ll want to use all the same size diapers. Varying the size of the diaper could skew your results. In your plant experiment, the temperature is a control variable.
