| Front | Back |
| How do you calculate a percentage of total in Tableau | Using the Percent of Total quick table calculation or by dividing a field's value by the sum of the field and formatting it as a percentage. |
| How does Tableau handle NULL values in calculations | Null values are ignored in aggregations but can be handled using functions like IFNULL or ZN. |
| How is a calculated field created in Tableau | By clicking on Analysis > Create Calculated Field or using the data pane's dropdown menu. |
| What does a "fixed LOD" (Level of Detail) expression aggregate | A specific dimension or set of dimensions regardless of other filters or aggregations. |
| What does the AVG function do | Calculates the average value of a numeric field. |
| What does the CONCAT function do in Tableau | Combines two or more strings into one continuous string. |
| What does the IF function do | Performs conditional tests to return different outcomes based on the test's result. |
| What does the LEFT function do | Extracts a specified number of characters from the start of a string. |
| What does the LEN function do in Tableau | Returns the length of a string (number of characters). |
| What does the SUM function do | Calculates the total sum of a numeric field. |
| What does the TRIM function do | Removes leading and trailing spaces from a string. |
| What is a calculated field | A field in Tableau created by combining or transforming data using expressions or formulas. |
| What is an aggregation | The process of summarizing data using methods like SUM, AVG, MIN, MAX, COUNT, etc. |
| What is the basic syntax for the addition operation in Tableau | A + B |
| What is the difference between MIN and MAX functions | MIN returns the smallest value, while MAX returns the largest value of a numeric field. |
| What is the purpose of arithmetic functions in Tableau | To perform mathematical operations like addition, subtraction, multiplication, and division. |
| What is the purpose of logical functions in Tableau | To evaluate conditions and return true/false or perform conditional operations. |
| What is the purpose of string functions in Tableau | To manipulate or transform text data fields. |
| What is the syntax for division in Tableau | A / B |
| What type of data does the COUNT function aggregate | Counts the number of rows or records in a dataset. |

About the Flashcards
Flashcards for the Tableau Desktop Foundations exam help students quickly review core calculation concepts used in Tableau. This deck covers calculated fields and how to create them, aggregation functions like SUM, AVG, MIN, MAX, and COUNT, and common arithmetic and logical operations (A + B, A / B, IF) so you can master terminology and function behavior.
Cards also reinforce string functions (LEN, CONCAT, LEFT, TRIM), Level of Detail (FIXED LOD) basics, table calculations such as Percent of Total, and approaches to handle NULL values in expressions. Use these concise prompts to test recall of syntax, purpose, and expected results on typical exam items.
Topics covered in this flashcard deck:
- Calculated fields
- Aggregation functions (SUM/AVG)
- Logical and arithmetic functions
- String functions (LEN, CONCAT)
- Level of Detail (LOD)
- NULL value handling
