  There are no point deductions for incorrect answers or questions you leave blank. Official AP graders will grade your free-response questions. Each of the six free-response questions is scored on a scale of 0 to 4 points, so the total section is out of 24 points. The free-response questions are graded holistically, which means, instead of getting a point or half a point for each bit of correct information you include, graders look at your answer to each question as a "complete package," and your grade is awarded on the overall quality of your answer.

  The grading rubric for each free-response question is: 4: Complete Response: Shows complete understanding of the problem's statistical components 3: Substantial Response: May include arithmetic errors, but answers are still reasonable and show substantial understanding of the problem's statistical components 2: Developing Response: May include errors that result in some unreasonable answers, but shows some understanding of the problem's statistical components 1: Minimal Response: Misuses or fails to use appropriate statistical techniques and shows only a limited understanding of statistical components by failing to identify important components 0: No Response: Shows little or no understanding of statistical components What does holistic grading mean for you? Basically, you can't expect to earn many points by including a few correct equations or arithmetic answers if you're missing key statistical analysis.

  Part A To answer this question, you'll need to analyze the histogram and see what information you can get from it. This can include the distribution of the histogram, its range, and its center. From the histogram, you can see that the distribution of Robin's tip amounts is skewed to the right. This makes the largest tip amount appear to be an outlier since no other tip amounts are near it. Include all these components in your answer. So the mean will increase by about 17 cents. It's the most in-depth question on the test, and you should spend about 30 minutes completing it. The Investigative Task will have several parts you need to answer and require multiple statistics skills. There's a lot going on here, but let's break the question down and go through it part by part. Part A This question wants to know if the scatterplot supports the newspaper's report about number of semesters and starting salary.

  Looking back at the question, we can see that the newspaper reported that the more semesters needed to complete an academic program at a university, the higher the starting salary for the first year at a job. Does the scatterplot support this? If it did, we'd see a positive association between starting salary and number of semesters: if one increases, the other would as well. Looking at the scatterplot, there is a clear positive association between starting salary and number of semesters, so the scatterplot does support the newspaper's report. What Graders Are Looking For Mentioning positive correlation Using positive correlation to justify that the scatterplot supports the newspaper report Part B There's a lot of information in the table, but we're interested in the numbers under the Coef or coefficient column since they are what apply to the least-squares regression line.

  As the constant, we know that Therefore, 1. We know that slope is the change in y over the change in x, or, in this case, the change in starting salary over the change in number of semesters. So the slope is telling us how much starting salary changes for each additional semester. Our slope is 1. This gives us 1, This means that, for every additional semester a program requires, predicted starting salary increases by 1, For part C, we're looking specifically at business majors, indicated by circles on the scatterplot.

  From the scatterplot, we can see that the more semesters a student takes, the lower their starting salary typically is. For example, we can see that a business major who took ten semesters has a lower average starting salary than someone who only took five semesters. Since as one variable increases the other decreases, that means there is a negative linear association between number of semesters and starting salary for business majors. What Graders Are Looking For States the association is negative States the association is strong or linear or both Refers to both variables salary and semesters in context Part D For this question you're being asked to compare the median starting salaries for the three majors. The first step to doing this is finding the median starting salary for each major. Since there are eight data points for each major, the median will be between the fourth and fifth largest starting salaries for each major.

  You don't need to be exact here; you can just eyeball the answer, and sketch in a line to the y-axis if it helps. For business majors, the fourth-highest salary looks to hit the y-axis around 39 and the fifth-highest salary to be around So the median starting salary for business majors would be about 38, euros remembering the y-axis unit is thousands of euros.

  Physics majors look to have a starting salary around 48, euros, and for chemistry majors the median is around 55, euros. Since you need to compare them, you'd mention that chemistry majors have the highest starting salary, physics majors are in the middle, and business majors have the lowest median starting salary. What Graders Are Looking For Correctly compares the three majors and which has the highest and which has the lowest median salary Gives reasonable values for the median salaries Part E How could the newspaper report be improved?

  Looking at the first scatterplot, it appears as though there is a positive correlation between number of semesters a student takes and their starting salary. We saw this in Part A. However, in the second scatter plot, which breaks average starting salary down by major, it's clear that, within a major, there is actually a negative correlation between the number of semesters a student completes and their average starting salary. We saw this in Part C. We saw in Part D that majors that require more semesters to complete tend to have higher starting salaries with chemistry having both the highest number of semesters and the highest starting salary. Within a major, students who take more semesters tend to have lower average starting salaries. The newspaper report should be modified to account for major so that readers can see that majors that require more semesters have higher average starting salaries, but, within a major, students who take a greater number of semesters tend to have lower average starting salaries.

In statistics, using the proper equation isn't worth much unless you can justify your answer.

If you're asked to compare three medians, don't just solve for the medians and list them; be sure to explain which is largest, which is smallest, and what that means in greater context.

  If you skimp on your responses, even if your math is perfect, you'll end up disappointed with your score. Don't be intimidated by long questions! Just focus on one part of the question at a time. You'll often discover that the individual parts of a question aren't that hard to solve on their own; it just looks like a lot at first glance. Also, while for other AP exams we sometimes recommend skipping around to whichever parts of different questions you feel most comfortable answering, for AP Statistics, we recommend starting at the beginning of each free-response question and methodically working your way through it.

  The answers you get for earlier parts of the question are often needed to answer later parts, so jumping around could cause you to waste time and end up confused. Confusing right- and left-skewed or random sampling and random allocation, for example, could cause to you to lose lots of points on the exam. To avoid these types of mistakes, stay on top of any new statistics terms you learn in class throughout the school year. Making flashcards of key vocab and quizzing yourself regularly is a great way to stay up-to-date on new terms.

  Many AP Stats prep books also include a glossary of important terms you should know. Before the AP Stats exam, you should know all important vocab words like the back of your hand. Having a general idea isn't good enough. As we mentioned earlier, a big part of stats is being able to support your answers, and to do this you'll often need to use stats vocab in your explanations.

  Just stating the term won't earn you nearly as many points as being able to explain what the term is and how it supports your answer. Because this question is worth three times as much as any of the other free-response questions, you want to make sure you answer it well, or it could really impact your final score. Leaving this question until the end could mean you run out of time before you answer it. We recommend answering the Investigative Task question second, after you've completed one of the shorter free-response questions. This ensures you have enough time to complete it. And remember, don't lose track of time on this section! You'll want to spend about 30 minutes on the Investigative Task and about 12 minutes on each of the other questions.
