WebFeb 2, 2024 · Unlike extrapolation, interpolation is a method of finding a value from the known values. In the case of linear interpolation, you might find the new data point from the two known data points. Let’s say, you know the values of two known points A (x 1,y 1) and C (x 2,y 2) of a straight line. WebTrend Analysis & Assumptions. Trend extrapolation is one aspect of the larger field of trend (or trendline) analysis. It attempts to extend known data points to regions beyond the timeframe of known datapoints, almost always in an attempt to predict future values with some degree of probability. However, the assumptions made are critical.
