1. Types of Variables

2. Variable
• A variable is anything that may assume
different numerical values.
• A variable is anything that can take on differing or
varying values.
• The values can differ at various times for the same
object or person, or at the same time for different
objects or persons.
• Examples of variables are absenteeism and
motivation.

3. Types of Variables
• Dependent Variable (Criterion variable)
• Independent Variable (Predictor Variable)
• Mediating Variable (Intervening variable)
• Moderating variable

4. Dependent Variable
• The variable of primary interest to the
researcher.
• Researcher's goal is to understand and
describe the dependent variable, or to
explain its variability, or predict it.
• In other words, it is the main variable that
lends itself for investigation as a viable
factor.

5. Dependent Variable
Examples:
Increase in Sales
Organizational performance
Employee performance
• It is possible to have more than one
dependent variable in a study.

6. Independent/Predictor Variable
Independent variable is one that influences
the dependent variable in either a positive or
negative way.
• When the independent variable is present,
the dependent variable is also present,
•
• With each unit of increase in the IV, there is
an increase or decrease in the DV.

7. Mediating Variable
• A mediating variable (or intervening
variable) is one that surface/float up/bridge
between the time the independent variable
start operating to influence the dependent
variable.
• The mediating variable explain the
influence of the independent variable on the
dependent variable.

8. Moderating Variable
• Moderating variable is one that has a strong
contingent/conditional effect on the
independent variable–dependent variable
relationship.
• It modifies the original relationship between
the independent and the dependent
variables.
