Three real describing the distribution of a quantitative variable questions

From the practice pool, not the mock papers — each with the reasoning that produces the answer.

92 practice questions sit on this single topic — enough that it is worth working through by topic rather than meeting it scattered through a unit review.

100% of them come with a figure. Reading the graph or diagram correctly is most of the work here before any content knowledge applies.

95% test a single AP skill: Using Probability and Simulation. That makes this topic unusually predictable to prepare for.

Using Probability and Simulation · with figure

A statistics class is examining displayed matrix scores. Which panel shows a distribution that is skewed right?

  1. APanel A
  2. BPanel B
  3. CPanel C
  4. DPanel Dcorrect
  5. EPanel E
Why D is correct

Panel D shows a distribution that is skewed right.

This is a strictblind AP Statistics figure item. The stem withholds the data needed to choose an answer, and the answer must be determined from the histogram rendered from render_spec. The matching histogram shape must be identified from the displayed panel. The answer key is recomputed from the structured answer_rule.

Using Probability and Simulation · with figure

The visual evidence comes from coded values. Which panel shows a distribution that is skewed left?

  1. APanel Acorrect
  2. BPanel B
  3. CPanel C
  4. DPanel D
  5. EPanel E
Why A is correct

Panel A shows a distribution that is skewed left.

This is a strictblind AP Statistics figure item. The stem withholds the data needed to choose an answer, and the answer must be determined from the histogram rendered from render_spec. The matching histogram shape must be identified from the displayed panel. The answer key is recomputed from the structured answer_rule.

Data Analysis · with figure

The graph below summarizes unit readings. Which panel shows a distribution that is approximately symmetric and mound-shaped?
