Cause-and-Effect Models can have multiple independent variables.

Cause-and-Effect Models can have multiple independent variables.

• A. True
• B. False
• C. Depends on the model
• D. Never

Answer: (A)

In cause-and-effect modeling, outcomes are often shaped by several factors, so models frequently include multiple independent variables. Each independent variable represents a distinct input you believe can influence the outcome, and including several lets you estimate each factor’s contribution while holding the others constant. This also lets you capture interactions between causes, which is common in real-world systems. For example, forecasting demand might consider price, advertising spend, and seasonality together, so you can see how each factor affects demand on its own and in combination with others. While some simple analyses use a single predictor, it’s standard practice to include multiple independent variables when multiple causes are plausible. So the statement is true.
