Regression analysis: Regression analysis is used to explore and quantify relationships between variables. It helps us understand how changes in one variable are associated with changes in another variable.
Sample slope: The sample slope refers to an estimated value of the population slope based on observed data from a sample rather than using information from an entire population.
Significance test: A significance test is used to determine if the relationship between variables (such as the population slope) is statistically significant. It helps us assess whether the observed relationship is likely due to chance or represents a true association.
