What are the three variables in science? Explain quickly
(happy Wednesday my dudes)

Answer 1

Explanation:

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

An independent variable is defines as the variable that is changed or controlled in a scientific experiment. ... Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable.

dependent variable is what you measure in the experiment and what is affected during the experiment. ... It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.

a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

Answer 2

What are the three variables in science?

ANSWER:-

Scientists use experiments to explore cause and effect. Several items could be changed to test the reaction of another and these changing quantities are called Variables which are any characteristic, aspect, or condition that can exist in differing quantities or samples.

An experiment has three variables:

An experiment has three variables: independent, dependent, and controlled.

• The Independent Variable is a variable that is changed by the scientist. To certify a fair test, a promising experiment has only ONE independent variable. As the scientist alters the independent variable, he or she documents the data that they obtain.

• The Dependent Variable is the variable that concedes to the alteration of the independent variable. The dependent variable depends on or changes with the change of the independent variable.

• The Controlled Variables are quantities or items that you want to persist constant and must examine as carefully as the dependent variables.
