Ensuring uniqueness

Before bringing out some insights from the data, you want to double-check that your dataset is clear of duplicates. You had a conversation with the IT department, and they mentioned that they found some errors with the code used to store the different student results.

So, to be safe, you will use the Unique tool to identify and remove duplicate values from your workflow.

If you lost any progress, load the 2_3_sample_show.yxmd from the Exercises folder on the Desktop.
