A statistical method modeling data with a curved equation, ideal for nonlinear trends resembling a U or inverted U shape. Quadratic Equation
A mathematical expression in the form ax² + bx + c, where the squared term introduces curvature to the graph. Coefficient of Determination
A value, often called R², indicating how well a model fits data; values near 1 show a strong fit. Graphing Calculator
A handheld device, such as the TI-84, used to input data, perform regression analysis, and graph equations. Best Fit Curve
A curve that most closely follows the pattern of data points, minimizing the overall distance from each point. Nonlinear Data
A dataset where the relationship between variables forms a curve rather than a straight line. Stat Menu
A calculator feature allowing users to enter, edit, and analyze statistical data for regression calculations. Y1
A calculator variable where regression equations are stored for easy graphing and visualization. R Squared Value
A numerical measure showing how closely the regression curve matches the actual data points. Predictive Analytics
The practice of using statistical models to forecast future outcomes based on current or historical data. Regression Analysis
A statistical approach for estimating relationships among variables, often used for prediction and modeling. Stat Plot
A calculator function that displays data points on a graph, aiding in visualizing regression results. Window Settings
Graphing calculator parameters that define the visible range for x and y axes, ensuring all data is displayed. Curvature
The degree to which a graph bends, determined by the coefficient of the squared term in a quadratic equation. Data Mining
The process of analyzing large datasets to discover patterns, often using regression techniques for insights.
