There are a couple of ways to deal with missing data. You can’t ignore missing data because many algorithms will not accept missing values. If an outlier proves to be irrelevant for analysis or is a mistake, consider removing it. This step is needed to determine the validity of that number. Remember: just because an outlier exists, doesn’t mean it is incorrect. ![]() However, sometimes it is the appearance of an outlier that will prove a theory you are working on. ![]() If you have a legitimate reason to remove an outlier, like improper data-entry, doing so will help the performance of the data you are working with. Often, there will be one-off observations where, at a glance, they do not appear to fit within the data you are analyzing. For example, you may find “N/A” and “Not Applicable” both appear, but they should be analyzed as the same category. These inconsistencies can cause mislabeled categories or classes. Structural errors are when you measure or transfer data and notice strange naming conventions, typos, or incorrect capitalization. This can make analysis more efficient and minimize distraction from your primary target-as well as creating a more manageable and more performant dataset. For example, if you want to analyze data regarding millennial customers, but your dataset includes older generations, you might remove those irrelevant observations. Irrelevant observations are when you notice observations that do not fit into the specific problem you are trying to analyze. De-duplication is one of the largest areas to be considered in this process. When you combine data sets from multiple places, scrape data, or receive data from clients or multiple departments, there are opportunities to create duplicate data. Duplicate observations will happen most often during data collection. Remove unwanted observations from your dataset, including duplicate observations or irrelevant observations. Step 1: Remove duplicate or irrelevant observations While the techniques used for data cleaning may vary according to the types of data your company stores, you can follow these basic steps to map out a framework for your organization.

For example, here's how the currency and percentage values look if you omit symbols. Make sure you add the appropriate symbol before or after a merge field. Go to Home, and in the Number group, select the Number Format box down arrow, and then choose an option in the list (such as Text). Leading zeros-for example, 00399-in codes are dropped during a mail merge if they're not formatted as text.Ĭhoose the column that contains the ZIP Codes, postal codes, or other data to be formatted.

Format a column of percentages as text if you want to avoid that multiplication factor. If you choose percentage as a category, be aware that the percentage format will multiply the cell value by 100. Format a column with numbers, for example, to match a specific category such as currency. ![]() In your Excel data source that you'll use for a mailing list in a Word mail merge, make sure you format columns of numeric data correctly. ![]() Save your spreadsheet with a new file name.
