What is interpolation in missing data?
Linear Interpolation means estimating a missing value by connecting dots in the straight line in increasing order. It estimates the unknown value in the same increasing order as the previous values. The default method used by Interpolation is Linear so while applying it one does not need to specify it.
How do I interpolate missing data in Excel?
To fill in the missing values, we can highlight the range starting before and after the missing values, then click Home > Editing > Fill > Series. What is this? If we select the Type as Growth and click the box next to Trend, Excel automatically identifies the growth trend in the data and fills in the missing values.
What is interpolation imputation?
While imputation replaces missing data for the column's mean, interpolation is a sort of estimation that creates data points within the range of a discrete set of existing data points.
