• Identifies and measures relationships between variables.
• Can be simple (one predictor) or multiple (two or more predictors).
• Produces a regression equation for prediction.
• Assumes a linear relationship between variables.
• Relies on statistical measures such as R-squared and p-values.
• Requires continuous or appropriately coded variables.

Why is linear regression analysis important in market research?        

It is important because it helps marketers predict outcomes such as sales, customer satisfaction or market share based on influencing factors, enabling data-driven strategy and resource allocation.
