Research Methods/Designs/Problems Flashcards
1
Q
Research Design
A
-structure of how the study is conducted
2
Q
Research Tools
A
-instruments, technology used to collect data
3
Q
Research Analysis
A
-statistic technology for extracting structure from data
4
Q
Types of Research Design
A
- Experimental Studies
- Correlation Studies
- Observational Studies
5
Q
Experimental Studies
A
- manipulate the independent variable (one you can’t control)
- random assignment
- control group
- goal: assert causality
- ex. facial feedback
6
Q
Correlation Studies
A
- measure 2 or more dependent variables
- subject variables
- statistical control
- goal: asses relationships
- ex. TV and mortality
7
Q
Observational Studies
A
- measure 1 or more dependent variables
- exploratory experiment
- no controls
- goal: identify phenomena
- ex. identify sexual orientation
8
Q
Experimental Issues
A
- External Validity
- Internal Validity
- Sampling
9
Q
External Validity
A
-generalizability
10
Q
Internal Validity
A
- cofounds: unintended difference
- does the experiment apple to the outside world?
- unintended independent variable
- experimenter bias
- single-blind studies: participant bias; placebo effect
- double blind studies: no one knows whats happening
11
Q
Sampling
A
- who should be in your study?
- members of group you are targeting
- Population: group under study
- Sample: individual who actually participate in your study
12
Q
Random Sampling
A
-everyone in the population has equal chance of being in the study as a sample
13
Q
Random Assignment
A
-taking members in the sample and assigning them to different conditions in the study
14
Q
Stratification
A
- make sure they have people on either extremes
- ex. really rich vs. really poor
15
Q
Research Tools: Low Technology
A
-surveys, observation, text analysis
