How do I interpret regression coefficients?
An example of an AI chatbot conversation about interpreting regression coefficients in statistics.
What do regression coefficients tell us in a statistical model?
Regression coefficients represent the relationship between independent variables and the dependent variable. They indicate how much the dependent variable is expected to change when the independent variable increases by one unit.
Can you explain what a positive coefficient means?
A positive coefficient means that as the independent variable increases, the dependent variable also tends to increase, indicating a direct relationship.
What about a negative coefficient?
A negative coefficient indicates an inverse relationship; as the independent variable increases, the dependent variable tends to decrease.
How do I know if a coefficient is statistically significant?
You can check the p-value associated with the coefficient. If the p-value is less than your significance level (commonly 0.05), the coefficient is considered statistically significant.
