What are the 4 variables?

There are four variables you have to deal with: resources, time, quality, and scope.

What is a dependent variable in science?

The dependent variable is the variable being tested and measured in an experiment, and is ‘ dependent ‘ on the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.

How do we identify variables?

The elements that change in an experiment are called variables. 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.

What is variable example?

What is major variable in research?

A variable is defined as anything that has a quantity or quality that varies. The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable.

What are variables in research study?

In research, variables are any characteristics that can take on different values, such as height, age, species, or exam score. The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause.

Which variable is the one you measure?

A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.
