How do you display rows with missing values?

How do you find the missing values in a column?

Missing values from a list can be checked by using the COUNTIF function passed as a logical test to the IF function. After the logical test, if the entry is found then a string “OK” is returned otherwise “Missing” is returned.

How do you indicate missing data?

A missing value is indicated by an empty cell or a . (full stop) or * (asterisk) in the cell. These values always indicate a missing value, regardless of measurement scale of the variable.
