Linear Regression Concepts

These flashcards cover essential vocabulary and concepts related to linear regression, including definitions of key terms and principles.

Linear Equation

An equation that represents a straight line using the formula y = mx + b.

Dependent Variable

The variable that is being predicted or is affected by another variable.

Independent Variable

The variable that is manipulated to determine the relationship with the dependent variable.

Slope

The measure of the steepness of the line, indicating how much y changes for a unit change in x.

Y-Intercept

The value of y when x is zero, indicating where the line crosses the y-axis.

Linear Regression

A statistical method used to model the relationship between a dependent variable and one or more independent variables.

Prediction in Linear Regression

Using the linear equation to estimate values of the dependent variable based on given independent variable(s).

Plugging in Values

Substituting x values into the regression equation to obtain predicted y values.
