week 3 Kind of Variables and Their Use Flashcards
is a characteristic of an individual or
organization that can be observed and measure, and it can vary among people or organizations being studied.
VARIABLE
root word “vary” or simply “can change”
VARIABLE
Age
Sex
Gender
Education
Income
Marital Status
VARIABLE
An attribute is a specific value on a _____
variable
A variable should have at least
2 attributes
Variables represent categories that CANNOT BE ORDERED in any particular way.
Nominal
They may come in any order.
Nominal
Consists of numbers which indicate categories for purely classification or identification purposes
Nominal
Variables represent categories that CAN BE ORDERED from greatest to smallest or vice versa.
Ordinal
the numbers serve as codes but must now be assigned in
consecutive order, indicating degree of level
Ordinal
Variables have values that lie along an evenly dispersed range of numbers.
Interval
Has all the properties of the ordinal scale; A scale that represents quantity and has equal units
Interval
A given interval (distance) between scores has the same meaning anywhere on the scale
Interval
Zero does not represent the absolute lowest value but
represents simply an additional point of measurement and not the absence of the property
being measured
Interval
Variables have all the properties of interval variable (represents quantity and has equality of units) and has
a clear definition of 0.
Ratio
The most informative scale as it tends to tell about the order and number of the object between the values
Ratio
Allows comparison of intervals or differences
Ratio
Has a true or absolute zero point (no numbers exist below zero, i.e., there are no negative numbers)
Ratio
are those that probably cause, influence or affect the outcomes. It is controlled and manipulated by the
researcher and applied on another thing, condition or process.
Independent Variables
are those that depend on the independent variables. They are exposed to the treatment or actions from the independent variables.
Dependent Variables
stand between the independent and dependent variables and they show the effects of the independent to the
dependent variables.
Intervening Variables
is a special type of independent variable that is measured in study because it potentially influences
the dependent variable. It must to be controlled so that the true influence of the independent variable on the dependent variable can be determined.
Control Variable
In an experiment, it is the variable that is constant or
steady.
Control Variable
