Tableau provides a wide range of calculations that you can use to analyze and visualize your data. Here are some of the different types of calculations available in Tableau:

  1. Aggregate calculations: These calculations allow you to perform aggregations, such as sum, average, count, and so on, on your data.
  2. Logical calculations: These calculations allow you to create logical expressions, such as IF THEN ELSE statements, to test conditions and return different results based on the outcome.
  3. Date calculations: These calculations allow you to perform operations on date fields, such as finding the difference between two dates, extracting the month or year from a date, and so on.
  4. String calculations: These calculations allow you to manipulate string fields, such as concatenating strings, extracting substrings, and so on.
  5. Statistical calculations: These calculations allow you to perform statistical operations, such as finding the median, mode, standard deviation, and so on, on your data.
  6. Window calculations: These calculations allow you to perform calculations across a set of rows, such as ranking data, finding the running total, and so on.
  7. Level of detail calculations: These calculations allow you to define custom sets of data, and perform calculations at different levels of granularity.

You can create calculations in Tableau by using the calculation editor, which is accessed through the "Analysis" tab in the toolbar. The specific calculations available to you will depend on the data you are working with and the type of analysis you want to perform.
