Which of the following is an example of qualitative forecasting?

Qualitative forecasting methods rely on subjective judgment and insights rather than on numerical data. The example that best fits this description is expert judgment or market research focus groups. These techniques involve gathering opinions and insights from individuals or groups to make predictions about future demand or trends. This approach is particularly valuable when historical data are scarce or when a new product is being introduced, as it incorporates personal expertise and perceptions about market conditions.

In contrast, time series analysis, linear regression, and statistical analysis of historical data are all quantitative forecasting techniques that focus on analyzing numerical data patterns and trends over time. These methods leverage mathematical models and historical performance figures to predict future outcomes, relying heavily on objective data rather than subjective insights. Thus, the use of expert judgment or market research focus groups distinctively characterizes qualitative forecasting.
