Question 1 · 1 mark · Difficulty 1/3

A farmer in St. Vincent recorded the number of coconuts harvested from 7 trees: 12, 15, 18, 15, 20, 15, 22. What is the mode of this data set?

  1. 12
  2. 15
  3. 18
  4. 17
Show answer & explanation
✓ Answer: B15
Award 1 mark for correctly identifying 15 as the value that appears most frequently (3 times). A is incorrect — 12 appears only once. C is incorrect — 18 appears only once. D is incorrect — 17 is the mean, not the mode.
Question 2 · 1 mark · Difficulty 1/3

For grouped data, the modal class is the class interval with the:

  1. smallest frequency
  2. highest frequency
  3. middle frequency
  4. largest class width
Show answer & explanation
✓ Answer: Bhighest frequency
Award 1 mark for understanding that the modal class contains the most data values. A is incorrect — this would be the least common class. C is incorrect — this confuses mode with median. D is incorrect — class width is unrelated to mode.
