How do I interpolate numbers in Excel?
I was trying to interpolate numbers by using Forecast, but it is not the
linear interpolation result I need. I am wondering is there a way to do it? Following is Forecast help example. By using Forecast, the result is 10.6, but if using interpolation, Known Y (7,9) Known X (28,31), the result should be 8.333 Known Y KnownX 6 20 7 28 9 31 15 38 21 40 Formula Description (Result) =FORECAST(30,A2:A6,B2:B6) Predicts a value for y given an x value of 30 (10.60725) Thank you very much in advance !!!!!! |
