• OPTIONS

Came from the word “vary,” are elements, entities, or factors that can change.

• OPTIONS

• CHOICES

• VARIABLES

• SUB UNIT

Are used to describe characteristics of a population, group, or sample of the population.

• DEMOGRAPHIC VARIABLES

• INDEPENDENT VARIABLES

• DEPENDENT VARIABLES

• ORDINAL VARIABLES

During the quarantine period, your mother planted tomato seedlings in pots. Now common understanding from science tells you that several factors are affecting the growth of tomatoes: sunlight, water, kind of soil, and nutrients in soil. How fast the tomato seedlings will grow and bear fruits will depend on these factors. What is the dependent variable?

• SUNLIGHT

• WATER

• THE GROWTH OF TOMATOES

• KIND OF SOIL

Factors that may influence the outcome (dependent variable) which are not manipulated or pre-defined by the researcher.

• MODERATOR VARIABLES

• DEPENDENT VARIABLES

• CONFOUNDING VARIABLES

• EXTRANEUOS VARIABLES

The factor which is measured, manipulated, or selected by the experimenter to discover whether it modifies the relationship of the independent variable to an observed phenomenon.

• CONFOUNDING VARIABLE

• MODERATOR VARIABLE

• ORDINAL VARIABLE

• DICHOTOMOUS VARIABLE

Odd one out

• DICHOTOMOUS

• NOMINAL

• ORDINAL

• INTERVAL

It has a numerical value and can be measured along a continuum.

• INTERVAL VARIABLE

• DICHOTOMOUS

• ORDINAL VARIABLE

• NOMINAL VARIABLE

This variable has no intrinsic order

• DICHOTOMOUS VARIABLE

• NOMINAL VARIABLE

• ORDINAL VARIABLE

• INTERVAL VARIABLE

Sometimes called an outcome variable

• RATIO

• DEPENDENT VARIABLE

• INDEPENDENT VARIABLE

• INTERVAL VARIABLE
