1. Understand the difference between qualitative and quantitative forecasting methods. Qualitative methods rely on expert judgment and opinions, while quantitative methods use historical numerical data and mathematical models.
2. Review each option to classify it as qualitative or quantitative: Linear regression is a quantitative method that models the relationship between variables using a mathematical equation.
3. Exponential smoothing is a quantitative method that applies weighted averages to past data to forecast future values.
4. The Delphi method is a qualitative forecasting technique that gathers expert opinions through multiple rounds of questionnaires to reach a consensus.
5. Moving average is a quantitative method that calculates the average of a fixed number of past data points to smooth out fluctuations and predict future values.
