Lecture 2 Flashcards
Researchers specialize by ?
- Substance
- Theoretical model
- Population
- Methodological approach
What is involved in the scientific method ?
- Ask the question
- Design the study
- Collect the data
- Analyze the data
- Report the results
What are the common designs ?
- Descriptive
- Case study
- Observational/correlational
- Quasi-Experimental
- Experimental
- Cross-sectional
- Longitudinal
What is descriptive ?
Quantifies (numbers)
What is case study ?
In-depth examination of the life of one person (qualitative)
What is observational/correlational ?
Studies naturally occuring relationships (no manipulation)
What is Quasi-Experimental ?
Studies impact of manipulation but no random assignment
What is Experimental ?
Studies impact of manipulation that is randomly assigned
What is involed in Experimental methods ?
- Experimental group
- Control group
- Placebo control group
What is between-group design ?
Individuals experience one condition and compared to other group
What is within-group design ?
Individuals experience multiple conditions and are compared to selves
What is cross-sectional ?
One time point
What is longitudinal ?
Multiple time points
What are the stengths and limitations of descriptive ?
- Strengths: not intrusive; best when using population-based samples vs convenience
- Limitations: not looking at cause and effect; limited to quanitifying single variables
What are the stengths and limitations of case-study ?
- Strengths: in-depth understanding
- Limitations: results cannot be generalized and cannot establish causality
