NYC Information Ordering and Visualization 3 — Questions and Answers
Question 1: A dispatcher must prioritize four incoming calls by urgency level (1=highest). Call W is level 3, Call X is level 1, Call Y is level 2, Call Z is level 4. In which order should calls be handled?
- X, Y, W, Z (Correct answer)
- Z, W, Y, X
- X, W, Y, Z
- Y, X, W, Z
Correct answer: X, Y, W, Z
Calls are handled from highest to lowest urgency: Level 1 (X), Level 2 (Y), Level 3 (W), Level 4 (Z).
Question 2: A table shows crime statistics with columns for Precinct, Total Crimes, Arrests, and Clearance Rate. A supervisor wants to find which precinct has the highest clearance rate. What is the most efficient approach?
- Read every row from top to bottom in order
- Sort the table by the Clearance Rate column in descending order (Correct answer)
- Calculate the average of all columns first
- Convert the table to a pie chart
Correct answer: Sort the table by the Clearance Rate column in descending order
Sorting by the target column in descending order immediately places the highest value at the top, eliminating the need to scan all rows.
Question 3: A civil service employee needs to file records using a color-coded system: Red = Active, Blue = Pending, Green = Closed. A file marked 'Case resolved; awaiting final signature' should be assigned which color?
- Red
- Blue (Correct answer)
- Green
- No color until signature is obtained
Correct answer: Blue
The case is resolved but awaiting a final step, placing it in a Pending (Blue) status rather than fully Closed.
Question 4: Which type of chart is MOST appropriate for showing how a city's population has changed continuously over 50 years?
- Pie chart
- Bar chart
- Line chart (Correct answer)
- Scatter plot
Correct answer: Line chart
Line charts are designed to display trends over continuous time periods, making them ideal for population change over decades.
Question 5: A clerk receives documents timestamped as follows and must arrange them chronologically: 10:47 AM, 9:15 AM, 1:02 PM, 11:30 AM, 8:58 AM. Which sequence is correct?
- 8:58 AM, 9:15 AM, 10:47 AM, 11:30 AM, 1:02 PM (Correct answer)
- 9:15 AM, 8:58 AM, 10:47 AM, 1:02 PM, 11:30 AM
- 1:02 PM, 11:30 AM, 10:47 AM, 9:15 AM, 8:58 AM
- 8:58 AM, 10:47 AM, 9:15 AM, 11:30 AM, 1:02 PM
Correct answer: 8:58 AM, 9:15 AM, 10:47 AM, 11:30 AM, 1:02 PM
Chronological order from earliest to latest: 8:58 AM, 9:15 AM, 10:47 AM, 11:30 AM, 1:02 PM.
Question 6: A report contains a data table and a bar chart showing the same information. The table shows Department A has 320 incidents while the chart's bar for Department A appears tallest. What should the reader conclude?
- The chart is wrong because tables are always more accurate
- The chart correctly visualizes the table data if 320 is the highest value (Correct answer)
- The bar should be re-drawn to match the table exactly
- Both sources must be discarded and the data recollected
Correct answer: The chart correctly visualizes the table data if 320 is the highest value
If 320 is the highest value in the dataset, the tallest bar correctly represents Department A's data, and both sources are consistent.
Question 7: An employee is asked to organize case files first by borough (alphabetically) and then by date (oldest first) within each borough. For the Bronx, which set of files is arranged correctly?
- Bronx Jan 5, Bronx Mar 2, Bronx Feb 14
- Bronx Feb 14, Bronx Jan 5, Bronx Mar 2
- Bronx Jan 5, Bronx Feb 14, Bronx Mar 2 (Correct answer)
- Bronx Mar 2, Bronx Feb 14, Bronx Jan 5
Correct answer: Bronx Jan 5, Bronx Feb 14, Bronx Mar 2
Within the Bronx, files must be sorted oldest-first: January 5, February 14, March 2.
