What is the simplest procedure for forecasting future outcomes based on past data?

1. Extrapolation

2. Regression analysis

3. Time series analysis

4. Causal modeling

The correct answer is: Extrapolation

Extrapolation is the process of estimating future values based on the trend of past data by extending that trend into the future. This method relies on the assumption that the past behavior of the data will continue in a similar manner. It is a straightforward means of forecasting, especially when the data shows a consistent pattern over time. In scenarios where the available data displays a clear trend, extrapolation can provide quick estimates without the complexity of more sophisticated statistical methods. For example, if sales have steadily increased over several quarters, one might extrapolate this trend to predict future sales, assuming that the underlying factors influencing that growth remain constant. While methods like regression analysis and causal modeling involve more intricate statistical techniques that can take into account various factors and their relationships, extrapolation serves as a foundational approach that is simpler and often used for a basic assessment of potential future values based on historical trends. Time series analysis, while useful for understanding data over time, often involves more complexity, such as seasonality and cyclical patterns, making it less straightforward than extrapolation.
