For example, if your marketing team hands off some leads to your sales team, the number of leads the marketing team records transferring should match up with the number of leads the sales team reports receiving. Relationship consistency is a measure of how well related pieces of data match up. if the sales team reported a different number of leads than the marketing team, that shows an inconsistency. Measuring the number of inconsistencies in your data can help you determine its overall quality. How to measure: There’s no exact metric for this. You simply list all the inconsistencies you find in the data.

5. Format consistency There’s another type of consistency Belgium Phone Number Data you can measure — format consistency. This refers to consistency in the way your data is formatted. Sometimes, different datasets will end up formatted in different ways, and you want to make sure everything is on the same wavelength. For example, maybe you’re tracking data on company names and emails. If one dataset formats company names by removing terms like “Inc.” and “LLC,” but another database always includes those terms, your data tools may not recognize that those two datasets belong to the same company. Locating any formatting inconsistencies is another way to see the quality of your data.



How to measure: Just like relationship consistency, there’s no set metric for this. You just list the inconsistencies you find, and that’s all there is to it. 6. Duplicate rate Duplicate rate refers to the percentage of your data points that are duplicates. Duplication isn’t uncommon in datasets — you’ll often find that some of the same pieces of information appear several times. Those duplicates can clutter up the datasets, so you’ll want to remove them. How to measure: To calculate duplicate rate, just compare the number of duplicate entries to the total number of data entries in the dataset. The percentage you get will be your duplicate rate.
