Confidence intervals for the slope of a regression model provide a range of plausible values for the true slope parameter. They indicate the uncertainty associated with estimating the relationship between two variables in a linear regression analysis.
Regression analysis: Regression analysis is a statistical technique used to model and analyze relationships between variables.
Coefficient of determination (R-squared): R-squared measures the proportion of variation in the dependent variable that can be explained by the independent variable(s).
Standard error: The standard error represents how much variability there is in estimating the true value of a parameter, such as the slope, from sample data.
