Answer
The correct answer is To find the total number of observations up to a certain point.
Explanation
The correct option is To find the total number of observations up to a certain point. To find the total number of observations up to a certain point 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.
