The independent variable is the variable that is changed in an experiment. a True b False

True.

Explanation:

An independent variable is what is changed by the scientist experimenting, or you. An easy way to remember this is that independent starts with an "I", which "I" am the one that manipulates the variable. A good experiment only has one independent variable.

A dependent variable is the data of the experiment. This could be the impact a drug has on individuals, how much a plant has grown, test scores of students, etc. What is measured at the end of an experiment is the dependent variable.

A control variable is something that is stayed constant throughout the experiment. This could be the amount of water, type of soil, amount of light, the color of light, etc. These things are not changed.
