1. Working with dates
In this video, we'll explore how to work with dates in Tableau.
2. Dates
In your analysis you will often want to understand when something happened. You'll ask questions like: when did a certain event take place, or what kind of seasonal trends do we see. Fortunately, Tableau makes this kind of visual discovery and analysis easy.
3. Date data
Dates are automatically placed in the Dimensions area of the Data pane and are identified by the date icon. For example, the Date dimension from the UN data source, which we will work with in the exercises, is shown on the slide.
4. Date hierarchy
Tableau provides a robust built-in date hierarchy for any date field. You can drill down from year, to quarter, to month, to day.
5. Business question
The question the World Health Organization wants to answer is the following: Is there seasonality to the number of births in Chile? If yes, during which month are the fewest babies typically born? Knowing this will help them plan how many resources should be sent over to ensure newborn care at birth throughout the year. By the end of this lesson you will be able to build a visualization that will help answer the question.
6. Let's practice!
Let's first look at how to do a similar analysis for Portugal before answering the business question.
