We should take note here that we jumped right into refining our data. Sometimes, especially if you are dealing with data completely new to you, you may spend time first exploring your data using the Watson Analytics Explore feature. We will spend time creating explorations later in this book, but for now it is good to mention, that if you refine a dataset, the changes that you make to it are available throughout Watson in Predict, Explore, and Assemble, but if you modify the data in an exploration, the changed data is available only in that exploration.
