Explanation

Regression analysis is the correct answer because it mathematically models the relationship between variables, allowing predictions of future values based on historical trends and patterns - the core purpose of forecasting.

Why the distractors are wrong:

B. Simple data aggregation merely summarizes data (sums, averages) without producing predictive models.
C. Data normalization rescales data to a standard range for consistency, not prediction.
D. Inferential statistics draws conclusions about populations from samples, but is a broad category rather than a forecasting method itself.

Memory tip: Think "regression = reaching back to predict forward" - it regresses on past data to project future outcomes, making it the natural fit for any time-based forecasting scenario.
