Study Notes
Research Problem
- The point of research is to investigate a specific subject within a broader field.
- The subject of the research is the variable being studied and measured.
- The aim of research is what the researcher hopes to achieve through the investigation.
Research Question
- A research question clearly states the problem the project aims to answer.
- It should be concise and finalized at the start of the study.
Quantitative Research Questions
- Quantitative research questions are precise and can be descriptive, comparative, or examine relationships.
Qualitative Research Questions
- Qualitative research questions are adaptable, non-directional, and more flexible.
- Examples of qualitative research questions are descriptive, exploratory, explanatory, generative, ideological.
Hypothesis
- A hypothesis is a testable prediction based on a logical argument derived from a literature review.
- A hypothesis is a statement that predicts the relationship between variables.
- Hypotheses are never proven, only supported or rejected.
Independent Variable (IV)
- The IV is the variable that is manipulated or changed by the researcher.
Dependent Variable (DV)
- The DV is the variable that is measured and influenced by the IV.
Types of Hypotheses
- There are different types of hypotheses, including:
- Null Hypotheses: States no relationship exists between variables.
- Alternative Hypotheses: States that there is a relationship between variables, which can be directional (predicting the direction of the relationship) or non-directional (not specifying the direction of the relationship).
Example Hypotheses
- Example 1: The independent variable is the new reading intervention. The dependent variable is student performance.
- Example 2: The independent variable is talking on the phone while driving. The dependent variable is errors on a driving course.
- Example 3: The independent variable is age. The dependent variable is performance on a memory task.
