Study Notes
Types of Research
-
Qualitative Research: Focuses on non-numerical data, exploring attitudes, behaviors, and experiences. Methods include:
- Case studies
- Content analysis
- Ethnography
- Interviews
- Observations
-
Quantitative Research: Focuses on numerical data, examining cause-and-effect relationships. Methods include:
- Experiments
- Surveys
- Correlational studies
- Regression analysis
Research Designs
- Experimental Design: Manipulates independent variables to measure their effect on dependent variables.
- Quasi-Experimental Design: Lacks random assignment, but controls for extraneous variables.
- Non-Experimental Design: Observes phenomena without manipulating variables.
- Survey Research: Uses questionnaires or interviews to collect self-reported data.
Data Collection Methods
- Primary Data: Original data collected specifically for the research study.
- Secondary Data: Existing data collected by others, often from published sources.
-
Sampling Methods:
- Probability Sampling: Every individual in the population has an equal chance of being selected.
- Non-Probability Sampling: Individuals are selected based on convenience or accessibility.
Data Analysis
- Descriptive Statistics: Summarizes and describes the sample data.
- Inferential Statistics: Makes inferences about the population based on sample data.
- Data Visualization: Uses graphs and charts to communicate data insights.
Research Ethics
- Informed Consent: Participants must understand the study's purpose, risks, and benefits.
- Anonymity and Confidentiality: Protecting participants' identities and data.
- Deception and Debriefing: Avoiding deception and providing participants with accurate information after the study.
Research Quality and Validity
- Internal Validity: Ensuring the study measures what it claims to measure.
- External Validity: Generalizing findings to the population and other contexts.
- Reliability: Consistency in measuring the variables.
