Study Notes
Key Concepts in Research Methodology
- A hypothesis is a testable statement that predicts the relationship between variables in a research study.
- Variables are measurable characteristics or factors that can vary or change in a research study.
- The independent variable is the variable that is manipulated or controlled by the researcher in an experiment.
- The dependent variable is the variable that is measured or observed and is expected to be influenced by the independent variable.
- A control group is the group in an experiment that does not receive the experimental treatment and is used as a baseline for comparison.
- Probability sampling is the process of selecting a sample from a population in such a way that each individual or object has an equal chance of being included.
- Quantitative research focuses on collecting and analyzing numerical data to answer research questions and test hypotheses.
- Qualitative research focuses on collecting and analyzing non-numerical data, such as interviews or observations, to gain in-depth insights into a research topic.
- Ethical considerations are the principles and guidelines that ensure the protection of participants' rights and well-being in a research study.
- Peer review is the process of evaluating and assessing the quality and validity of a research study by experts in the field before it is published.
- Theory is a well-substantiated explanation or framework that explains a phenomenon or set of observations.
- Replication is the process of conducting a study again using the same methods and procedures to determine if similar results are obtained.
