The t-test for the slope of the regression line assesses whether there is sufficient evidence to conclude that there is a linear relationship between two variables in regression analysis.
Picture yourself driving on a road with different slopes. The t-test for slope helps determine if there's enough evidence to conclude that the road is truly inclined or if it's just a random variation in the terrain.
Regression Analysis: A statistical technique used to model and analyze the relationship between variables.
Coefficient of Determination (R-squared): A measure that indicates how well the regression line fits the observed data points.
