Question
- A. To display the frequency of each individual data point
- B. To show how many observations fall below certain values
- C. To calculate the median of a data set
- D. To find the range of a data set
Answer
The correct answer is To show how many observations fall below certain values.
Explanation
The correct option is To show how many observations fall below certain values. To show how many observations fall below certain values 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.
