In a simple linear regression analyzing monthly sales volume, what is the dependent variable?

• A. Monthly marketing budget
• B. Sales volume
• C. Advertising channels
• D. Market demographics

Answer: (B)

In the context of simple linear regression, the dependent variable is the outcome or response variable that the model aims to predict or explain based on one or more independent variables. In this scenario, the focus is on monthly sales volume, which is the variable that researchers are trying to understand or predict based on other factors, such as the marketing budget or advertising strategies. Since the primary purpose of regression analysis is to analyze and quantify the relationship between the independent variables and the dependent variable, recognizing monthly sales volume as the dependent variable is essential. This understanding allows for insights into how various factors influence sales performance, enabling better decision-making in areas such as marketing and sales strategies. The other options listed (marketing budget, advertising channels, and market demographics) would be considered independent variables that might affect the sales volume but are not the outcome that the regression analysis seeks to measure or predict.
