5. 
CONTINUOUS VARIABLE
-A variable that can take infinite number on the value
that can occur within a population.
-its values can be divided into fractions.
-ex; age, height, and temperature
DISCRETE VARIABLE
-also known as categorical or classificatory variable.
-any variable that has a limited number of distinct values
and which cannot be divided into fractions like sex, blood group,
and number of children in the family.
Continuous and Discrete
Variables

6. 
Categories/Nature of the Variables
1.Interval Variable –is a measurement where the
difference between two values does have meaning.
1.Ex; The difference between a temperature in 60
degrees and 50 degrees is the same difference as
between 30 degrees and 20 degrees. The interval
between values makes sense and can be interpreted.
2.Ratio Variable –possesses the properties of interval
variable and has a clear definition of zero, indication
that there is none of that variable.
Continuous Variables

7. 

2. Ratio Variable –possesses the properties of interval
variable and has a clear definition of zero,
indication that there is none of that variable.
Ex; height, weight, and distance
Continuous Variables

8. 
Categories/Nature of the Variables
1.Nominal Variable
-is a variable with no quantitative value.
-it has two or more categories but does not
imply ordering of cases.
Ex; eye color, business type, and religion
* Dichotomous –a sub type of nominal scale with only
two categories just like sex (e.g. male/female)
Discrete Variables

9. 
Categories/Nature of the Variables
2. Ordinal Variable
-is a variable that has two or more categories which can be
ranked.
Ex;
1.if you asked people if they like listening to music while
studying and they could answer either “not very much”,
“much”, or “Very much”
2.Educational attainment as a variable on a survey (elementary =
1, high school = 2, college undergraduate = 3, and college
graduate = 4)
Discrete Variables

10. 
Dependent variable –a variable that changes because of
another variable; The dependent variable is the factor that
is observed and measured to determine the effect of the
independent variable; the effect or outcome variable.
Ex; affects test grades
Independent Variable –A variable that is presumed to
cause changes in another variable; It is manipulated or
selected by the experimenter to determine its relationship
to an observed phenomenon; the causal variable
Ex; Amount of studying
Variables in terms of Roles

11. 
Mediating/Intervening Variable –A variable that comes
in between other variables; helps to delineate the process
through which variables affect one another. An
intervening variable is the factor that theoretically effects
observed phenomena but can not be seen, measured, or
manipulated
Ex; amount of studying leads to input and
organization of knowledge in one’s long term
memory which affects test grades
Variables in terms of Roles

12. 
Moderator Variable –A variable that delineates how a
relationship of interest changes under different
conditions. The term moderate variable describes a
special type of independent variable, a secondary
independent variable selected to determine if it affects
the relationship between the study’s primary
independent variable and its dependent variable.
Ex; Perhaps the relationship between studying and
test grades changes according to the level of use of a drug
such as Ritalin
Variables in terms of Roles

13. 
Control variable: Control variables are factors controlled
by the experimenter to cancel out or neutralized any
effect they might otherwise on the observed phenomena.
A single study can not examine all of the variables in a
situation (situational variable) or in a person
(dispositional variable); some must be neutralized to
guarantee that they will not exert differential or
moderating effects on the relationship between the
independent variables and dependent variables.
Variables in terms of Roles

14. 
Categorical Variable –a variable that is made up of
different types of categories of a phenomenon
ex; gender is made up of two categories, male
and female
Quantitative Variable –a variable that varies in
degree or amount of phenomenon
ex; annual income varies from 0 to a very high
level income
Variables in terms of level of
measurement
