Checking for Missing Data

Ann K. Emery — Sun, 21 Dec 2014 23:49:25 +0000

First, you’ll need to determine how many people are in your dataset (and much missing data you’re dealing with).

I teach you how to use three formulas to scan for missing data:

=count() tells you how many cells contain numeric data
=countblank() tells you how many of those cells are empty
Then, use =sum() to make sure the =count() and =countblank() add up

Spark Lines and Spark Bars

Spark lines and spark bars — miniature within-cell bar charts available in Excel 2010 and higher — are one of my favorite features of Excel. I use them to explore the patterns in my dataset, to see the highs and lows in my table, to think about what kinds of additional analyses I might want to conduct, and to get ideas for more formal charts that could be shared with my colleagues or clients in a report or presentation.
