Previously I share about 3 reasons why you should invest in a modern data stack.
Now let me share with you 3 techniques you can use in cleaning a data set.
- Removing duplicates. One of the most common techniques for cleaning a data set is to remove any duplicate records. This can help ensure that the data is accurate and free from inconsistencies, and can also save space and reduce the overall size of the data set.
- Handling missing values. Another important technique for cleaning a data set is to handle any missing or incomplete values. This can involve imputing missing values using statistical techniques, or simply removing records with missing values if they are not essential to the analysis.
- Standardizing and normalizing data. To make sure that data from different sources or formats is consistent and comparable, it may be necessary to standardize and normalize the data. This can involve converting data to a common format, scaling values to a common range, or applying other transformations as needed.
There are definitely more techniques to clean a data set and that’s for you to discover.
