Q1) What is Tableau?
A) Tableau is a powerful data visualization tool that allows users to connect to various data sources, create interactive dashboards, and generate insightful reports. Tableau is the Business Intelligence (BI) industry’s most potent and fastest tool for visualizing data. It turns the raw data into a format that is easy to understand. Tableau makes it faster to look at the data. Dashboards can be used to create visualizations. Data visualizations or diagrams make it easy for employees at all levels of an organization to understand the information.

Q2) What are the different data connection options available in Tableau?

A) Tableau provides various data connection options, including Excel spreadsheets, text files, databases (such as SQL Server, Oracle, MySQL), and web data connectors.

Q3) How can you create a calculated field in Tableau?

A) To create a calculated field in Tableau, you can right-click in the data pane, select “Create Calculated Field,” and then enter the desired formula or expression using Tableau’s calculation syntax.

Q4) What is the difference between a dimension and a measure in Tableau?

A) In Tableau, a dimension is a categorical or qualitative variable that represents the characteristics or attributes of the data, while a measure is a quantitative or numerical variable that can be aggregated or summarized.

Q5) How can you create a dashboard in Tableau?

A) A tableau dashboard is the final step in creating the visualization. First, make all of the charts in separate sheets. Then, click “add new dashboard” in the tab where you add new worksheets. You can also right-click on the “Add new sheet” button and choose “Add new dashboard” instead of “sheet.” To create a new dashboard differently, click Dashboard in the toolbar. Once you’ve done one of those three things, you’ll be brought to a new dashboard where you can begin piecing together your story by dragging the relevant sheets from the left panel onto the dashboard individually.

Q6) What is data blending in Tableau?

A) Data blending is a technique in Tableau that allows you to combine data from multiple data sources based on a common field or key. It enables you to analyze and visualize data that resides in different databases or files. Data blending is a more advanced way of combining two different data sources.

Q8) How can you perform data aggregation in Tableau?

A) Tableau provides various aggregation functions, such as SUM, AVG, MAX, MIN, COUNT, etc., which can be applied to measure fields. To perform aggregation, you can drag a measure field to the visualization and choose the desired aggregation function.

Q9) What are the different types of charts available in Tableau?

A) Tableau offers a wide range of charts, including bar charts, line charts, pie charts, scatter plots, maps, treemaps, heat maps, and more. Each chart type is suitable for different types of data and analysis purposes.

Q10) How can you share your Tableau workbooks with others?
