Data Visualization Design Quiz 2 16 Aug 2026 — Question 10

Select all that apply.

1. A

   Because operators frequently monitor the display peripherally from across the room, encoding alerts with motion would remain effective where hue and shape discrimination fall away

2. B

   If the utility expands from 35 stations to 120, alert detection time will stay roughly flat in Grid 1 but rise roughly in proportion to station count in Grid 2

3. C

   The alerts are found pre-attentively in Grid 1 because the orange marker is unique along the hue channel, and that uniqueness is what Grid 2 destroys

4. D

   Providing a clear legend for the category colours would restore the rapid detection of maintenance alerts in case of Grid 2.

5. E

   Making the alert orange more saturated than every category colour is sufficient to restore popout, since saturation outranks hue in the channel ranking

6. F

   Grid 2 can satisfy both requirements by encoding station categories with shape while reserving colour (hue) exclusively for maintenance alerts.
