How does Excel deal with missing values in data analysis?

Some techniques for imputing values for missing data include:

  1. Substituting the missing data with another observation which is considered similar, either taken from another sample or from a previous study.
  2. Using the mean of all the non-missing data elements for that variable.
  3. Using regression techniques.

How do I interpolate a missing value in Excel?

How do I ignore missing data in Excel?

Let’s take an example and understand how you can ignore blank cells when performing calculations.

  1. Select the cell C2.
  2. Enter the formula =IF(AND(ISNUMBER(A2), ISNUMBER(B2)),A2*B2,” “)
