The importance of removing duplicate data

It seems like in today's digital age, we are constantly collecting and storing vast amounts of data in various formats such as spreadsheets, databases, and tables.

In IS101, chapter 5.9.3 Table Customization video, I learned how to remove duplicate information from my tables.  Doing so is essential for maintaining data accuracy and quality, plus it saves time.  Duplicate data refers to multiple entries of the same data in a dataset.  This can be problematic for lots of reasons and can negatively impact data analysis.

In my opinion, one of the primary reasons for removing duplicate information from your tables and spreadsheets is to maintain data accuracy.  I remember one time, I kept scratching my head thinking why are the calculations wrong with my monthly budget worksheet and I then found the culprit, a duplicate data entry that was entered when I imported data from a different application. I don't have to tell you that I wasted time trying to sort through data and trying to identify duplicates and YES! I deleted them manually.  

I now audit my datasets to identify and remove duplicate information.  Another lesson learned!

  6. This is a straightforward way to get rid of any duplicate content without deleting them entirely; instead, the Advanced filter option hides your duplicates from your dataset.
