1. Types of quantitative research: descriptive, correlational, quasi-experimental, experimental
ex. Likert scale, statistical analysis
2. Descriptive studies: 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, classi�es the phenomena of interest or its characteristics
3. Correlational studies: Systematic investigation of relationships between or among two or more variables
(an association)
*Nature of relationship is NOT cause and e ect*; 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.
-Measures the numerical strength of relationships between and among 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.
4. Correlation measurement (statistic): 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)

5. Quasi-experimental studies: Used to identify causal relationships, to examine the signi�cance of causal
relationships, to clarify why certain events happened, or for a combination of these objectives
-Interventional
-Examines cause-and-e ect relationships among independent and dependent variables.
-Tests the hypothesis of a cause-and-e ect relationship when an experimental design can not or should not be used.
6. A quasi-experiment lacks... (one of these): a researcher enacted intervention, the presence of
a distinct control group, *random assignment to the group*
7. Experimental studies: Tests causal relationships with three criteria: (1) researcher intervention, (2) sepa-
rate, distinct control group, (3) random assignment to the group
-Interventional
-Examines cause-and-e ect 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 e ect on a dependent variable
8. Epidemiologic studies: Foundation for disease control and prevention through tracking the prevalence
of the disease, characterizing the natural history, and identifying determinants or causes of the disease.
It de�nes risk factors for a disease and targets for preventative medicine.
9. Types of qualitative research: phenomenology, grounded theory, ethnography
ex. focus groups, observations, interviews
10. Grounded Theory Research (Glaser and Strauss): Seeks to understand key psychological
processes that are grounded in reality
- Initial description in a non-researched area, basis of social interactions, often generations theory
- Focuses on discovery of a basic psychological social problem that a de�ned group of people experience
-Explains social psychological processes and social structures
-Has a number of theoretical roots (ex. symbolic interaction)
11. Phenomenological research: Focuses on lived experiences of humans (describes human experience)
(a description and interpretation of people's lived experience)
-Acknowledges people's physical ties to their world ("being in the world")
