What is the dependent variable in the experiment

Answers

Answer:

An experiment has two types of variables, dependent and independent.

  • Independent variable is decided by the person doing the experiment and can be changed at any time.
  • Value of dependent variable depends on the independent variable and it is not under the control of the person conducting the experiment.
  • As the value of independent variable changes, the value of dependent variable will also change according to the relationship between them.

It is a variable that counts on what the experiment is depending on like if glue needs to stick something together you'd wright about that.
