- A. To estimate values within the range of a data set
- B. To estimate values outside the range of a data set
- C. To calculate the average of a data set
- D. To identify the mode of a data set
Answer
The correct answer is To estimate values within the range of a data set.
Explanation
The correct option is To estimate values within the range of a data set. To estimate values within the range of a data set is correct because it directly matches the approved learning objective to interpolate and extrapolate trends. 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.
Common mistake
Confusing Interpolation and Extrapolation
Students often confuse interpolation with extrapolation, using extrapolation when they should be interpolating within the data range.
Remember that interpolation is estimating values within the range of the data, while extrapolation is estimating values outside the range.
