In today’s data-driven world, paying for commercial data doesn’t automatically ensure data quality. This was a crucial lesson learned during a recent engagement with one of our clients.
Our client had invested in commercial data to address a specific problem. However, they began the data exploration phase, and they noticed something unusual. Numeric fields were zeroed out for specific geographies but not for others. While it might be reasonable for this field to be zero, the disproportionate presence of zeros in certain geographies raised a red flag.
Digging deeper, they discovered that the data was being misrepresented. If left unchecked, this misrepresentation would have adversely affected their model’s performance, leading to potentially flawed insights and decisions.
This experience underscored the importance of conducting simple yet effective quality checks, such as examining the percentage of null or zero values in each feature. Such checks can be powerful indicators of data quality and help identify potential issues early in the process.
In the realm of data science, ensuring the quality of data is paramount.
Even simple checks, like analyzing the percentage of null and zero values for each feature, can serve as strong data quality indicators. This experience underscores the importance of due diligence in data analysis. For businesses, partnering with data quality assurance specialists like Ready Signal can save significant time and resources, ensuring data integrity from the outset.
