Very helpful. Thanks so much
Thanks a lot for this! Easy to understand:)
3:04 Actually you cannot conclude that the 2nd row is duplicate. Maybe the Email value of the 2nd row is wrong and 2nd row is a unique row.

Or maybe the FirstName AND Email value of the 2nd row are wrong or another issue. But, I designed this example of redundancy in my video (Jack and John are nicknames of each other). Thank you for sharing your thought.

Thank for sharing this amazing content! Dumb question: is data quality a area that a software QA can work in or is it a different position/role/profession?

Thiago Fragoso - Thank you for your positive comment! Though software QA can contribute to data quality, it's a specialized role focusing on data quality management and improvement. For example, the Data Quality Analyst may need extensive domain knowledge and provide high-quality data to Data Science teams, DevOps teams and of course QA.

very helpful, I hv data , but unable to identify the potential data quality issues in the variables and mechanism to deal with these data quality issues.

If you already have the data, you can explore it by plotting it. This way, you could see the potential data quality issues visually.

Excel is good. Or you could use Python libraries to plot the data.

data redundancy and data quality both are same..?

@murali chiyan - The simple answer is no, data redundancy is an issue of data quality. Good data should exactly one copy (non-redundant) for data integrity reason. However, sometimes data is duplicated (across partitions or disks or devices) for fault tolerance or performance reasons. That data redundancy by design is not an issue. Hope that I was able to clarify your query! Thank you!
