Study Notes
Quantitative and Qualitative Research
- Research can be categorized in various ways.
- Quantitative research focuses on numerical data, while qualitative research explores non-numerical data.
Variables
- Variables are characteristics or attributes that can be measured or manipulated in research.
- Independent variable: a factor that is manipulated by the researcher.
- Dependent variable: a factor that is measured to see the effect of the independent variable.
- Extraneous variables: factors that could influence the outcome but are not the focus of the study.
Research Problem
- Identifying a clear research problem is crucial for any study.
- A well-defined research problem provides direction and focus to the study.
- It should be specific, measurable, achievable, relevant, and time-bound (SMART).
Formulating Hypothesis
- Hypotheses are testable statements about the relationship between variables.
- Null hypothesis (H0): states there is no relationship between variables.
- Alternative hypothesis (H1 or Ha): represents the opposite of the null hypothesis.
- Specific predictions about the expected result of the experiment
- Help to structure and summarize the research question
Experimental and Control Groups
- Experimental groups receive an intervention or treatment.
- Control groups do not receive the intervention.
- Comparing results between groups allows researchers to assess the intervention's impact.
- Crucial for isolating causal effects and minimizing confounding variables
