Putting it all together

Let's clean up a digital marketing data set using Data Validation!

In this exercise, we will take this table, which reports on two different digital marketing sources, and apply Data Validation to fix any issues. This data set was filled in by multiple digital marketing professionals.

As we learned earlier, this means that there may be a few issues, as data entry is almost never perfect. The challenge here will be to apply different types of Data Validation that we have learned throughout this chapter to pin-point any issues with the data.
