Study Notes
Types of Research Methods
-
Qualitative Research: Focuses on collecting and analyzing non-numerical data to gain insights into people's attitudes, behaviors, and motivations.
- Methods: Case studies, interviews, focus groups, content analysis
-
Quantitative Research: Focuses on collecting and analyzing numerical data to test hypotheses and predict outcomes.
- Methods: Surveys, experiments, polls, statistical analysis
Research Designs
-
Experimental Design: Manipulates one or more independent variables to observe their effect on a dependent variable.
- Example: Investigating the effect of a new medication on blood pressure
-
Quasi-Experimental Design: Lacks random assignment of participants to groups, but still compares outcomes between groups.
- Example: Comparing student performance between two different teaching methods
-
Survey Research: Collects data through self-reported measures, such as questionnaires or interviews.
- Example: Investigating public opinion on a social issue
-
Case Study: In-depth examination of a single case or a small number of cases.
- Example: Analyzing a company's marketing strategy
Data Collection Methods
- Primary Data: Collected directly by the researcher through experiments, surveys, or observations.
- Secondary Data: Already exists and is collected from other sources, such as literature reviews or existing datasets.
Data Analysis
- Descriptive Statistics: Summarizes and describes the basic features of the data.
- Inferential Statistics: Makes inferences about a population based on a sample of data.
- Qualitative Data Analysis: Identifies patterns and themes in non-numerical data.
Research Ethics
- Informed Consent: Participants must understand the research and give their voluntary consent.
- Anonymity and Confidentiality: Protecting participants' identities and ensuring their responses remain confidential.
- Deception and Debriefing: Avoiding deception and debriefing participants after the study.
