It can be created by entering a list of values corresponding to any set of measurable items. Method to calculate interpolation step value in Excel Firstly, we will acquire excel graph with very little data values. In this tutorial we will extrapolate Excel graph to find predicted values. We can find out extended values on a graph by the help of the formula instead of the data.

Here we discuss How to Use Linear Interpolation in Excel along with practical examples and downloadable excel template. This is a guide to Linear Interpolation in Excel. But still, Forecast function helped us to interpolate the runs with the help of data of previous matches.

In this example, data was not linear and you can see that in the below graph.

After applying the formula, we get the result of Runs if we 8 wickets falls on the basis of a linear regression of last 9 matches played by the team. We have data of the last 9 matches of the cricket team which has wickets gone and runs scored by the team. Even if we calculate the value manually, it will still give us the same result. In this example Forecast function interpolate the value based on all data available and not just starting and Endpoint.Īs you can see in the charts, profit is moving is exactly the same as sales. The result for the Forecast function will be Rs. So with the help of Forecast function, we can interpolate the profit of when sales is Rs. You have sales data from to and you want to know what should be the profit if your sales is Rs. If we look at the below chart of the above example, we can say the data set has a linear relationship and known as linear interpolation. Basically, it is used to calculate the future value based on the Existing values of a specific data set. Forecast is a Worksheet Function available in MS Excel and it uses linear regression to find out the missing value.įorecast as its name suggests it is used to forecast the future value of a data point, but it can also be used to interpolate a value. Now we will learn this function in detail now.

This is an example of how to calculate the missing values with the help of a manual formula to understand interpolation.

In school, we used to use the below formula to calculate the missing value of Y. Based on our example, it is 30 Cell A4 minus 60 Cell A2the result of which is then multiplied by 1 which equals Finally, the first section of the formula in brown above we add the first value of the speed of the bike. The second section in blue above calculates how far our speed of bike is away from the first speed of bike given, then multiplies it by the value calculated above. In the above example, the last section of the formula which is highlighted in red calculates how much time taken changes whenever the speed of bike changes by 1. We need to insert the below formula in cell B4. Using simple mathematics, we can calculate the missing values in the above example. Interpolation estimates the value based on the existing available data values which are relatable. In the world of mathematics, interpolation is a method of creating new data points with the help of known data points.
