Learning Microsoft Power BI - Column Settings and Hierarchies In Power BI

The video tutorial covers important column settings in Power BI, including the distinction between data type and formatting, hiding columns, renaming and deleting columns, and creating hierarchies. It emphasizes the importance of setting the correct data type for columns to enable specific functions and discusses how to streamline the report view by hiding unnecessary columns. The tutorial also demonstrates how to create hierarchies to simplify data visualization.

What is the primary purpose of setting a data type for a column in Power BI?

• To determine the color of the data

• To define the types of operations that can be performed on the data

• To set the background image of the report

• To decide the font style of the data

Why might you choose to hide certain columns in your Power BI data model?

• To prevent accidental deletion

• To reduce visual clutter in the report view

• To increase the loading speed of Power BI

• To enhance the color scheme of the report

How can you ensure that a column is not visible in the report view but still part of the data model?

• By hiding it in the data model settings

• By deleting it from the report view

• By changing its data type to 'hidden'

• By renaming it to 'invisible'

What happens when you rename a column in Power BI?

• It adds a step in Power Query to reflect the change

• It hides the column from the report view

• It deletes the column from the data model

• It changes the data type of the column

What is the effect of deleting a column in Power BI?

• It changes the column's data type

• It hides the column temporarily

• It renames the column

• It removes the column from the data model permanently

What is a key benefit of creating hierarchies in Power BI?

• It allows for automatic data type conversion

• It automatically formats the data for printing

• It enables simultaneous visualization of multiple columns

• It increases the number of available data sources

Which of the following is NOT a step in creating a hierarchy in Power BI?

• Dragging columns into a group

• Renaming the hierarchy

• Adding the hierarchy to a visualization

• Deleting the original columns
