A researcher compares the number of road accidents recorded in one district during January with those recorded in another district throughout an entire year. What should be corrected to make the comparison fairer?

Answer and explanation

Correct answer: Compare data covering equivalent time periods

Accident totals can increase when a longer period is observed. Comparing equivalent periods helps avoid misleading conclusions, although traffic volume and population may also need consideration.
