Regression is a way to find patterns in data. Regression helps researchers understand or predict how one thing changes based on another. It helps us use past information to make smart guesses about what might happen next. For example, if we know how study time affects test scores, we can use that pattern to predict future scores.
The thing regression is trying to predict is called the response variable (or dependent variable) because it depends on something else, called dependent variable(s). in the above example test score is response variable and study time is dependent variable.
