- 1. Defining 2. hypothesis 3. gather data problem. 4 analyzing data 5. interpreting data.
-
-
Applied Research
- Goal: immediate solutions
- Approach: real-world settings
- done with a specific question or application in mind
-
Basic Research
- Goal: theory- driven
- Approach: Laboratory
- Deals with theoretical concepts, has no immediate concern with application done just for knowledge
-
Independent variable
The part of the experiment that the researcher is manipulating
-
Ecological validity
- Does the setting have enough of the real-world characteristic to allow generalization to identity
- the reach setting perceived by the research participant in the way intended by the experimenter
-
Experimental research
type of research that involves the manipulation of treatments in an attempt to establish cause and effect relationships
-
Dependent Variable
The effect of the independent variable also called yield
-
Hypothesis
educated guess, expected result
-
Internal Valididty
the extent to which the results of a study can be attributed to the treatments used in a study
-
external validity
the generalization of the results in a study
-
Descriptive Research
- concerned with status
- to describe the status of the study's focus
- common techniques are questions, interviews normative survey, case studies, job analysis , observational research
-
primary resource
first hand source of data in research, original study
-
Secondary Research
source o f data in research in which an author has evaluated and summarized previous research
-
standard error
the variability of the sampling distribution
-
variability
the degree of difference between each individual score and the central tendency score
-
central tendecny
a single score that best represents all the scores
-
Post hoc
Justification that the sample represents some group at large
-
Stratified random sampling
