Understand basic regression concepts without heavy math.
Regression models estimate relationships between variables. Focus on interpreting coefficients sign positive/negative , magnitude effect size , and uncertainty confidence intervals . Remember correlation does not imply causation; consider omitted variables and confounders. Visualize relationships with scatterplots and fitted lines to see patterns. Use regression as a tool for description and prediction, and be cautious when making causal claims without experimental or quasi experimental designs.
