Step 1: Introducing variable

Variables are key elements that are crucial for comprehending, quantifying, and describing occurrences in the world of research and data analysis. The fundamental elements of research investigations and statistical analyses are variables, which are traits, qualities, or amounts that can have various values. They are used to quantify and explain different facets of our environment, enabling researchers to explore connections, anticipate the future and reach insightful conclusions. Variables in research can be categorised into a variety of types such as independent variables, dependent variables, categorical variables and continuous variables, each of which has a particular function in the research process.
