Study Notes
Types of Research
- Qualitative Research: Focuses on exploring attitudes, behaviors, and motivations through non-numerical data (e.g., interviews, observations, texts).
- Quantitative Research: Focuses on numerical data and statistical analysis to identify patterns and trends.
Research Designs
- Experimental Design: Manipulates an independent variable to measure its effect on a dependent variable.
- Quasi-Experimental Design: Lacks random assignment, but still attempts to establish cause-and-effect relationships.
- Survey Research: Collects self-reported data through questionnaires or interviews.
- Case Study Research: In-depth examination of a single case or a small number of cases.
Data Collection Methods
- Primary Data: Original data collected through experimentation, surveys, or observations.
- Secondary Data: Existing data collected from other sources (e.g., literature reviews, datasets).
- Self-Report Measures: Participants provide information about themselves through questionnaires, interviews, or diaries.
- Observational Measures: Researchers observe participants' behavior in natural or controlled environments.
Sampling Techniques
- Probability Sampling: Random selection from a population to ensure representativeness.
- Non-Probability Sampling: Non-random selection, often due to convenience or accessibility.
Data Analysis
- Descriptive Statistics: Summarizes and describes the basic features of the data.
- Inferential Statistics: Makes inferences about a population based on a sample.
- Qualitative Data Analysis: Identifies themes, patterns, and codes in non-numerical data.
Ethical Considerations
- Informed Consent: Participants must understand the research and provide voluntary consent.
- Anonymity and Confidentiality: Protect participants' identities and data.
- Debriefing: Inform participants of the research's true purpose and any deception used.
Research Limitations
- Internal Validity: The degree to which the research design and methodology ensure accurate results.
- External Validity: The extent to which the results can be generalized to other populations and contexts.
- Sampling Bias: Systematic errors in the sampling process that affect the representativeness of the sample.
