- B. They can only be used for discrete data
- C. They do not show trends in data
- D. They are always linear
Answer
The correct answer is They always start at zero on the y-axis.
Explanation
The correct option is They always start at zero on the y-axis. They always start at zero on the y-axis is correct because it directly matches the approved learning objective to use cumulative frequency where appropriate. This belongs to Statistical skills within Statistical skills, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Statistical skills, reverse the geographical relationship, or make a broader claim than the objective supports.
