What is Linear Regression?
A statistical method used to model the relationship between a dependent variable and one or more independent variables by fitting a linear equation to observed data, allowing analysts to predict continuous outcomes based on input features.
Linear Regression,
explained properly.
Not a flashcard answer — the working meaning, where you'll meet it, and why professionals who use it precisely get taken more seriously.

Understanding Linear Regression on paper is one thing — using it confidently at work is another. In professional settings, this is the kind of term that separates people who talk about Predictive Modelling from people who are trusted to make decisions in it. Recruiters and managers listen for it in interviews, and colleagues notice immediately whether you use it precisely or vaguely.
At OnlineUni, Linear Regression is taught inside the module “Statistical Foundations For Modelling” of Certificate in Predictive Modelling, where it is placed in its full working context — applied to real Predictive Modelling scenarios, not memorised in isolation.
