Variables in Research

An entity that can take on different values; An aspect of a theory that can vary or change as part of the interaction within the theory; Anything that can affect or change the results of a study; These are needed to understand differences.

• Variable

• Independent Variable

• Dependent Variable

• Research

Anything can be a variable; Something that a researcher is interested in.

• True

• False

• Depends

It is anything that has a quantity or quality that varies.

• Variable

• Dependent Variable

• Independent Variable

The outcome/result variable or the measurement; presumed effect.

• Dependent Variable

• Variable

• Independent Variable

The variable that can be manipulated/changed; presumed cause.

• Dependent Variable

• Variable

• Independent Variable

A type of variable with values that describe a measurable numerical quantity.

• Numeric

• Categorical

• Experimental

• Non-experimental

A type of numeric variable that assumes any number between a certain set of real numbers depending on the scale used. Takes fractional (non-whole number) values that can either be a positive or a negative.

• Continuous/Interval Variables

• Discrete Variables

• Secret Variables

• barya balls

A type of numeric variable that can assume any whole value within the limits of the given variables. These are countable whole numbers and does not take negatives or values between fixed points.

• barya balls parin

• Discrete Variables

• Continuous/Interval Variables

• Secret Variables

Variables with values that describe a quality or characteristic of a data unit.

• Numerical

• Categorical

• Experimental

• Non-experimental

A type of categorical variable that simply defines groups of subjects. Here you may have more than 2 categories of equivalent magnitude.

• Nominal variables

• Ordinal variables

• Dichotomous variables

• Polychotomous variables
