Step-by-step explanation:
There are auto-generated in Tableau is: a. One.Tableau is a powerful data visualization tool that automatically generates certain fields when you connect to a dataset. One of the fields that Tableau auto-generates is 'Number of Records', which is a measure representing the count of rows in your dataset. Each row is counted as one, regardless of the data within it. Apart from this auto-generated measure, users can create additional measures based on their dataset's specific needs. Tableau allows for extensive customization and calculation creation to suit different analytical requirements.
During analysis, the presence of built-in, auto-generated measures like 'Number of Records' simplifies the initial steps of exploring data and provides a quick way to gauge dataset size. While 'Number of Records' is provided by default, users will often spend time creating additional measures for meaningful data analysis, such as sums, averages, or more complex calculated fields. Remember that the effectiveness of these measures depends on the context of the data and the questions you are seeking to answer with Tableau's visualization capabilities.
