Study Notes

Understanding Variables

A variable represents changing qualities or characteristics, such as age, gender, or intelligence.
Rooted in the word "vary," it signifies the capacity for change or difference.
Variables are measurable, manipulable, and controllable.

Types of Variables

Independent Variables
- Affect dependent variables and are presumed causes in research.
- Researchers manipulate these variables to see their effect on others.
- Examples include the impact of online learning platforms on student performance and the effectiveness of teaching methods on math scores.
Dependent Variables
- These depend on independent variables and are examined for change.
- Also referred to as outcome or effect variables.
- Examples include the influence of music genre on workplace productivity and the impact of exercise on mental health.
Extraneous Variables
- Identified as variables that do not fit into the categories of independent or dependent.
- Can undesirably influence experimental results, such as age or personality traits.

Research Topic Development

Selecting and defining the research topic is the first crucial step.
Identify a broad and interesting topic that resonates personally and has community significance.
Ensure the topic aligns with the relevant field of study.

Steps for Research Design

Preliminary Research
- Involves gathering background information by reading relevant articles and studies.
- Understand how data was collected, analyzed, and what findings were reported.
Defining the Problem
- Post-research, list questions or problems for investigation.
- Narrow down the broad topic into specific, manageable research questions by focusing on particular populations, locations, periods, or characteristics.
Refining the Question
- Evaluate the formulated questions to ensure clarity and feasibility.
- Consider time constraints and resource availability in the research process.

Research Title Guidelines

The research title encapsulates the main idea of the paper and is a focal point for readers.
Use an accurate description of the subject matter without general terms or abbreviations (except well-known ones).
Avoid introductory phrases like “The study of” or “An analysis of.”
Include all main dependent and independent variables in the title.
Ensure proper grammar, punctuation, and capitalization of key words.
Generally, titles should be declarative but can also be formulated as questions if applicable.
Historical studies may include the year of research but it should not be included in other types of studies.
Utilize current terminology relevant to the topic.
