54). What is a Dimension?

Ans: The Columns shelf creates the columns of a table, while the Rows shelf creates the rows of a table. You can place any number of fields on these shelves.
When you place a dimension on the Rows or Columns shelves, headers for the members of that dimension are created. When you place a measure on the Rows or Columns shelf, quantitative axes for that measure are created. As you add more fields to the view, additional headers and axes are included in the table and you get an increasingly detailed picture of your data.
For example, the members of the Segment dimension are displayed as column headers, while the Profit measure is displayed as a vertical axis.

56). What is card? 
Ans: Every worksheet contains a variety of different cards that you can show or hide. Cards are containers for shelves, legends, and other controls.
For example, the Marks card is where you control mark properties. It contains the mark type selector along with controls for Color, Size, Label, Detail, Tooltip, Shape, and Angle. The controls that are available depend on the mark type.

57). Whenever a Measure is drag and dropped onto a shelf, it does a SUM. How would a user change it to a Median? *Practice in Bronze Study Workbook 
Ans: Right click on a measure (green) or column shelf and choose 'Measure->Median'

58). How would a user replace a measure or dimension on the rows or columns shelf?
Ans: Drag and drop field over the current field on the shelf. The new field will replace the other field.

59). What is a group in Tableau Desktop? Why is it important? 
Ans: A group is a combination of dimension members that make higher level categories.
In Tableau there isn't any coding or scripting required to group. Other software grouping can require coding or scripting which is difficult and time consuming.
