Well along a straight line, so you know that this data is appropriate for use The dataĪnd an XY plot of the data are shown in Figure Month and how it relates to the amount that is spent on advertising. Suppose that your company has been keeping track of the amount of sales each The function returns the Y value that is predicted for the specified X value,īased on the known X and Y data. Up-that is, the first X value goes with the first Y value, and so on. Ranges must each contain the same number of values, and they must match You have probably figured out that the known_y_values and known_x_values Known_x_values is a range containing the known X data values.Known_y_values is a range containing the known Y data values.X is the X value for which you want to predict the Y value.Here is the syntax for FORECAST(): =FORECAST(x, known_y_values, known_x_values) Not a serious restriction because a lot of data is linear. (Scatter) chart, the points will fall approximately on a straight line. This means that if you plot the known X,Y values on an XY Then, given an X value for which you do not have the Y, it predicts the Y How does FORECAST() work? It requires that you have a set of known X,Y data
Likewise, if you ask people about their educational level and annual
For example, if you have height and weight measurementsįrom a bunch of people, you have a set of X,Y pairs, with X as height and Y as The FORECAST() function forecasts unknown data based on existing data.įORECAST() works with data that comes in pairs, usually called X,Y pairs. With your predictions, and we’ll look at two of them in this article. Excel provides you with several functions that can help That the future will to some degree reflect the past, you might even be able to In some situations, particularly when you have reason to believe No one can predict the future, but that does not stop a lot of people from
