Question

Variables
An experiment has three main variables. The first is an independent variable, this is the only variable that is changed during a scientific experiment and is usually denoted with an "I." The next variable is the dependent variable, which is a variable that is dependent on the independent variable and is usually denoted with a "D." The last variable is the control, which is a group under normal conditions that is not experimental.

Answer 1

The role of the dependent variable in an experiment is to respond to the changes made to the independent variable. It is the variable that is being measured and observed based on the changes made to the independent variable. The dependent variable is dependent on the independent variable, and its role is to show the effects or outcomes of the changes made during the experiment.
