When it comes to exploring data, you can learn quite a bit by diving into the numbers! Before you can really dive into data analysis, however, you may need to do some data wrangling, also known as data munging, to clean up your data.

As you can see from the example in the video, you may need to work with a data set that is incomplete or has incorrect values.

Looking at this table, you will see that there are missing values and incorrect values. That’s where data wrangling and data munging comes into the picture. Data wrangling is the art of dealing with and / or converting missing or ill-formatted data into a format that more easily lends itself to analysis.
