Trend Extrapolation Involves

Trend extrapolation involves

A) extending a pattern observed in past data into the future.
B) selecting specific points on a graph of sales or market share, multiplying by the cost of living index, and allowing for a variation of plus or minus 3 percent.
C) averaging the total sales or market share for the previous five years and multiplying that number by the expected GDP growth rate for the next year (say 1.5 percent) to arrive at the next year's forecast.
D) selecting a given percentage and using that number as a yearly predictive base regardless of changes in sales, revenue, or market share.
E) collecting projections from all regional sales managers and making the final projection.
