In a line listing kept during an outbreak investigation, what does each column represent?
AA different day of the outbreak
BAn important variable being recorded
CA different reporting laboratory
DA different case under investigation
Answer & Solution
Correct answer: B. An important variable being recorded
1. A line listing is a table that holds the key data items for every case found.
2. Each column carries one important variable, such as identification number, age, sex or case classification.
3. Each row carries one case, and new rows are added as more cases are identified.
4. Reading columns as cases reverses the layout, which is the trap in the last option.
