read more calculates or predicts the future value based on existing values and a linear trend. If we know the past data, we may use the function to forecast the future value. Let us see in brief these formulas before we go ahead.įORECAST() – This Forecast excel function Forecast Excel Function The FORECAST function in Excel is used to calculate or predict the future value based on existing values and the statistical value of the forecast. We have to use a few formulas in Excel like FORECAST Excel Like FORECAST The FORECAST function in Excel is used to calculate or predict the future value based on existing values and the statistical value of the forecast. read more for the data to pull out the temperature value for the required time zone, which may be any time, not only the exact hour. It can be applied in estimating varied concepts of cost, mathematics, statistics. It approximates the value of a given function at a given set of discrete points.

We will perform interpolation Interpolation Interpolation is the mathematical procedure applied to derive value in between two points having a prescribed value. In the hour column, we mention the hours from the start of the day, like 12:00 AM would be 0 hours, 1:00 AM would be 1 hour, and so on.

We have the time zones for the entire day in the on-time column. The data shows that we have got the temperature details of the Bangalore region for some date.
