Question

Matching the following concepts to their definitions

1. The dependent variable 2. The independent variable(s) 3. The Least Square Method 4. Scatter diagram 5. The residual 6. T 7. b1 8. b0 This list outlines key concepts in statistical modeling and regression analysis: 1. **The Dependent Variable**: The outcome factor that researchers aim to predict or explain. 2. **The Independent Variable(s)**: Factors that are presumed to affect the dependent variable. These are manipulated or categorized to observe their effect on the dependent variable. 3. **The Least Square Method**: A mathematical procedure used in regression analysis to find the line of best fit. It minimizes the sum of the squares of the differences (the residuals) between observed and estimated values. 4. **Scatter Diagram**: A graphical representation of the relationship between two quantitative variables. Points represent data pairs and can reveal correlations or patterns. 5. **The Residual**: The difference between observed and predicted values in a regression model. It indicates the error or deviation from the fitted line. 6. **T**: Often refers to the t-statistic used in hypothesis testing, providing insights into the significance of individual coefficients in a regression model. 7. **b1**: The slope coefficient in a linear regression equation. It represents the change in the dependent variable for a one-unit change in the independent variable. 8. **b0**: The intercept of the regression line. It represents the expected value of the dependent variable when all independent variables are zero.

The image contains three text boxes, each with a drop-down icon: 1. The first box states, "In this procedure we minimize the sum of the squared residuals." 2. The second box indicates, "This is used to denote the slope coefficient." 3. The third box explains, "This is used to denote the intercept." No graphs or diagrams are present in the image.
