問題文

After connecting to a CSV, a field named Postal Code appears as a number (aggregated with SUM) and cannot be plotted on a map. Which change lets the analyst map it correctly?

選択肢

1. Change the field to a dimension and assign it the appropriate geographic role, such as ZIP Code/Postal Code.
2. Convert the field to a continuous measure so it can be placed on an axis.
3. Create a calculated field that multiplies the postal code by one.
4. Add the field to the Detail shelf and Tableau will map it automatically.
