Which two forecasting methods are subjective? Choose 2 answers.

Rationale

Executive opinion and customer opinions are the two subjective forecasting methods.

Both methods rely on personal judgment and intuition rather than purely quantitative data, making them subjective in nature. While they can provide valuable insights based on experience and perceptions, their inherent subjectivity can also lead to biases in forecasting outcomes.

A (Decomposition) YOUR ANSWER

Decomposition is a quantitative forecasting method that involves breaking down data into its constituent components, such as trend, seasonal, and cyclical factors. This method relies on statistical analysis rather than subjective judgment, making it an objective forecasting approach that does not fit the criteria for subjectivity.

B (Executive opinion) CORRECT

Executive opinion is a subjective forecasting method where predictions are made based on the insights and intuition of executives or managers. This approach draws heavily on personal experience and judgment, often reflecting the biases of those making the forecasts, thereby categorizing it as subjective.

C (Market testing) YOUR ANSWER

Market testing is an objective method that involves gathering data through experiments or trials in the market to assess potential outcomes. This approach relies on observable data and consumer behavior rather than subjective interpretation, distinguishing it from subjective forecasting methods.

D (Exponential smoothing) YOUR ANSWER

Exponential smoothing is a statistical technique that uses historical data to forecast future values, giving more weight to recent observations. It is a mathematical and objective method, employing algorithms to generate forecasts rather than personal judgment, thus excluding it from the subjective category.

E (Customer opinions) CORRECT

Customer opinions represent a subjective forecasting method that gathers insights from consumers to guide predictions. This approach is based on individual perceptions and preferences, which can vary greatly and introduce bias, aligning it with other subjective methods.

F (Moving averages) YOUR ANSWER

Moving averages is a quantitative forecasting technique that smooths out fluctuations in data by averaging values over a specified period. This method is based on numerical data rather than personal judgment, making it objective and not fitting into the subjective category.

Conclusion

In forecasting, subjective methods such as executive opinion and customer opinions rely on personal judgment and intuition, making them inherently biased. In contrast, methods like decomposition, market testing, exponential smoothing, and moving averages are rooted in quantitative analysis, providing a more objective foundation for predictions. Understanding the distinction between subjective and objective methods is crucial for accurate forecasting and decision-making.
