CITATIONS AND REFERENCING STYLES

Introduction to Citation

Citation is the practice of acknowledging the sources of information, ideas, or data that you include in your academic or research writing. It serves to give credit to the original authors and helps readers trace the origin of your statements. Citations are crucial in avoiding plagiarism, supporting your arguments with evidence, and enhancing the credibility of your work.

Introduction to Referencing

Referencing refers to the complete bibliographic information provided at the end of a document or research paper, allowing the reader to locate the original sources that were cited.

Understanding Variables in Research: A Simple Guide

In the world of research, variables are like the moving pieces that help us understand patterns, relationships, and outcomes. Whether you’re conducting a small survey or a full scientific study, identifying and understanding your variables is key.

What Are Variables?

A variable is anything that can change or vary. In research, it's a characteristic or value that you observe, measure, or manipulate. Think of it like this: if it doesn’t stay the same for everyone, it’s probably a variable!

Examples of variables:

Age

Gender

Income level

Weight

Education level


Categories of Variables

Variables can be grouped in several ways depending on how they behave and the role they play in a study.


1. By Their Nature (Type of Data)

This has to do with whether the variable is described by words (categories) or numbers.

a. Categorical Variables (Qualitative)

These deal with categories or groups.

Nominal: No order or ranking
Examples: Gender, Blood type, Religion

Ordinal: Has a logical order, but gaps between values aren’t consistent
Examples: Satisfaction level (low, medium, high), Education level (primary, secondary, tertiary)


b. Numerical Variables (Quantitative)

These are measured with numbers.

Discrete: Countable, no in-between values
Examples: Number of children, Test scores

Continuous: Can take any value within a range
Examples: Height, Temperature, Time



2. By the Type of Information

Here, we look at what kind of data is being described.

Qualitative Variables: Non-numerical characteristics
Examples: Eye color, Type of food, Extent of satisfaction 

Quantitative Variables: Numerical and measurable
Examples: Salary, Distance traveled


Note: Qualitative variables often fall under the “categorical” group, while quantitative variables are typically “numerical.”


3. By Their Role in Research (Cause and Effect)

This classification shows how variables function in the context of your study.

a. Independent Variable (IV)

The cause or factor you manipulate.

Example: Type of exercise program


b. Dependent Variable (DV)

The outcome you measure.

Example: Weight loss


c. Control Variable

A factor you keep constant to avoid it affecting your results.

Example: Diet during an exercise experiment


d. Moderator Variable

A variable that affects the strength or direction of the relationship between IV and DV.

Example: Age might moderate the effect of a training program on performance.


e. Mediator Variable

Explains how or why an IV affects a DV.

Example: Motivation may mediate the relationship between rewards and performance.


Final Thought

Before you begin your research, pause and ask:

What am I trying to measure?

What’s causing the change?

What needs to be kept constant?

How are these variables related?


Answering these questions gives you a strong foundation for any successful study.
