Tableau Mapping Geographic Data 3 — Questions and Answers
Question 1: Which map type in Tableau uses color intensity across geographic regions to show a measure?
- Filled (choropleth) map (Correct answer)
- Symbol map
- Density map
- Flow map
Correct answer: Filled (choropleth) map
A filled or choropleth map shades polygons by a measure's value.
Question 2: Which mark type is required to create a filled map of US states?
- Map (Correct answer)
- Circle
- Bar
- Line
Correct answer: Map
Setting the Marks card to Map fills each geographic area as a polygon.
Question 3: A symbol map differs from a filled map primarily because it represents data as what?
- Sized/colored marks at point locations (Correct answer)
- Shaded country borders
- Heat clouds
- Animated paths
Correct answer: Sized/colored marks at point locations
Symbol maps place individual marks (like circles) at locations, often sized by a measure.
Question 4: Which map type is best for visualizing dense overlapping points such as crime incidents in a city?
- Density (heatmap) map (Correct answer)
- Filled map
- Pie map
- Bar chart
Correct answer: Density (heatmap) map
Density maps reveal hotspots where many marks overlap by blending intensity.
Question 5: On a symbol map, dragging a measure to Size accomplishes what?
- Scales each mark proportionally to the measure (Correct answer)
- Changes the map background
- Filters out null values
- Adds a trend line
Correct answer: Scales each mark proportionally to the measure
Placing a measure on Size makes proportional symbol maps where mark area reflects value.
Question 6: To build a dual-axis map combining filled regions and point symbols, you must do what with Latitude?
- Add two Latitude (generated) pills and select Dual Axis (Correct answer)
- Delete the Longitude pill
- Convert Latitude to a dimension
- Use Measure Names
Correct answer: Add two Latitude (generated) pills and select Dual Axis
Two Latitude pills set to Dual Axis layer a filled map beneath symbol marks.
Question 7: Which map type would you choose to display the value of a single measure as graduated circle sizes by region?
- Proportional symbol map (Correct answer)
- Choropleth map
- Flow map
- Spider map
Correct answer: Proportional symbol map
Proportional symbol maps use circle size to compare a measure across locations.
