Correct Answers
Types of quantitative research Correct Answer ✓✓ descriptive,
correlational, quasi-experimental, experimental
ex. Likert scale, statistical analysis
Descriptive studies Correct Answer ✓✓ Accurate portrayal or account
of characteristics of a particular individual, situation, or group
-Performed when collective knowledge about a phenomenon is
incomplete: either no research has been conducted, or there is limited
research knowledge
-Purpose is to observe, describe, and document aspects of a situation
(not cause probing)
-Describes phenomena (ideas) in real-life situations
-Counts, measures, classifies the phenomena of interest or its
characteristics
Correlational studies Correct Answer ✓✓ Systematic investigation of
relationships between or among two or more variables (an association)
,*Nature of relationship is NOT cause and effect*; the only way to prove
this is through quasi-experimental or experimental study
-You can only say that there is a relationship between the two.

variables
-Discovers whether a change in a value of one is likely to occur when
another increases or decreases.
-Changes in X do not necessarily CAUSE changes in Y (this can not be
assumed without random controlled study)
-Changes in X are said to be RELATED to changes in Y.
Correlation measurement (statistic) Correct Answer ✓✓ Can be
measured for -1 to +1
-1 is a perfect negative correlation
+1 is a perfect positive correlation
0 indicates no relationship
Can be referred to as "r" in a published report (moderative neg
correlation r = -0.53)(strong correlation r = 0.82)
Quasi-experimental studies Correct Answer ✓✓ Used to identify causal
relationships, to examine the significance of causal relationships, to
, clarify why certain events happened, or for a combination of these
objectives
-Interventional
-Examines cause-and-effect relationships among independent and

researcher enacted intervention, the presence of a distinct control group,
*random assignment to the group*
Experimental studies Correct Answer ✓✓ Tests causal relationships
with three criteria: (1) researcher intervention, (2) separate, distinct
control group, (3) random assignment to the group
-Interventional
-Examines cause-and-effect relationships between independent and
dependent variables.
-Tests the null hypothesis by means of *applying an intervention to
experimental subjects*, but not to control subjects; and then measuring
the effect on a dependent variable
Epidemiologic studies Correct Answer ✓✓ Foundation for disease
control and prevention through tracking the prevalence of the disease,
