Linear Models
Linear models are mathematical tools used to describe relationships between variables. They work on the principle that changes in one variable (like hours studied) can predict changes in another (such as exam scores). In a linear model, this relationship is represented as a straight line on a graph, defined by a formula that includes a slope and an intercept. The slope indicates how much one variable affects the other, while the intercept shows the starting point when the first variable is zero. Linear models are widely used in statistics, economics, and science to make predictions and understand data.

Linear models are mathematical tools used to describe relationships between variables. They assume that changes in one variable predict changes in another in a straight-line manner. For instance, if you know the number of hours studied, a linear model can estimate the likely score on a test. These models are valuable in various fields, from economics to biology, as they help analyze trends, make predictions, and understand how different factors interact. Their simplicity makes them easy to interpret, though they may not capture more complex relationships found in real-world data.
