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. Why just one?

['The independent variable is the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.', 'The dependent variable is the variable that is measured by the experimenter.']

The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable.

A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. ... It is called a variable because the value may vary between data units in a population, and may change in value over time.

Types of Primary Data Before scientists can begin working on a question that interests them, they need to formulate a research hypothesis. ... There are four types of hypothesis scientists can use in their experimental designs: null, directional, nondirectional and causal hypotheses.
