Transcript text: Which of the following is a qualitative forecasting method?
A. linear regression
B. Delphi method
C. trend projection
D. naive approach
Solution
The answer is B: Delphi method.
Explanation for each option:
A. Linear regression - This is a quantitative forecasting method that uses statistical techniques to model and analyze the relationships between variables. It involves numerical data and mathematical computations, making it a quantitative approach.
B. Delphi method - This is a qualitative forecasting method that relies on the expertise and judgment of a panel of experts. The experts provide their opinions and forecasts independently, and through a series of rounds, they refine their predictions based on feedback. This method does not rely on numerical data but rather on expert insights, making it qualitative.
C. Trend projection - This is a quantitative forecasting method that involves analyzing historical data to identify patterns or trends and projecting these into the future. It uses numerical data and statistical techniques, classifying it as a quantitative method.
D. Naive approach - This is a simple quantitative forecasting method that assumes future values will be the same as the most recent observed value. It relies on numerical data and is considered a quantitative approach.
