# Transformation dataset statistics

It can be useful to review the statistics for the transformed dataset. These show the names of all the elements in your transformed dataset, the count, whether the values are distinct, and the average length of an element. By clicking on the name of an element you can also view the data in this element. Reviewing the statistics can be particularly helpful when you are considering editing a mapping to improve the transformation.
