Two factories report worker ages. Factory A's modal class is 30-40 with mode 36; Factory B's modal class is also 30-40 but its mode is 33. Keeping l = 30 and h = 10 the same for both, what does a higher mode within the same modal class indicate?

Class 10Mode of Grouped DataStatistics and Probability
  • AThe class succeeding the modal class has a relatively higher frequency in Factory A
  • BFactory A has fewer workers
  • CFactory A's class size is larger
  • DNothing can be concluded

Step-by-Step Solution

A larger mode within the same modal class means the fraction is larger, which happens when 2 (succeeding class) is relatively higher, pulling the mode toward the upper end.
Answer: A) The class succeeding the modal class has a relatively higher frequency in Factory A
