In Tableau, what is the difference between 'Discrete' and 'Continuous' fields?
Answer: Discrete fields produce headers and color-code as blue; continuous fields produce axes and color-code as green
Tableau color-codes discrete (blue) pills to create headers and continuous (green) pills to create quantitative axes.
Which Tableau chart type is most appropriate for showing how a value accumulates over an ordered dimension such as time?
Answer: Running Total line chart using a table calculation
A line chart with a RUNNING_SUM() table calculation incrementally sums values across each time period.
What is the purpose of using a 'Set Action' in Tableau?
Answer: To dynamically update a set's membership based on user interaction with marks in the view
Set Actions allow marks clicked or hovered by the user to add, remove, or replace members in a set in real time.
In Tableau, what does the 'Disaggregate Measures' option under the Analysis menu do?
Answer: It plots each individual row as its own mark instead of aggregating measures
Disaggregate Measures bypasses aggregation so every underlying data row is rendered as a separate mark.
Which statistical model does Tableau use when you add a 'Trend Line' with the 'Linear' option?
Answer: Ordinary least squares (OLS) regression
Tableau fits a linear trend line using OLS regression, minimizing the sum of squared residuals.
What is the result of placing the same dimension on both the Rows shelf and the Color encoding in a Tableau view?
Answer: Each row header also gets a unique color, visually reinforcing the dimension breakdown
Placing a dimension on both Rows and Color is valid and causes each dimension member to have its own row and matching color.
In Tableau, how does a 'Relative Date Filter' differ from a 'Range of Dates' filter?
Answer: A relative date filter dynamically adjusts to always show data relative to today, while a range filter uses fixed start and end dates
Relative date filters automatically shift the window (e.g., 'last 30 days') as time progresses, whereas range filters stay fixed.
