1 AP Statistics Summer Packet 2016 If you have any questions regarding the expectations or instructions for this packet, please Part 1 Directions: Please define the following terms using your book or other resources. Populations: Samples: Census: Sample Survey: Sampling Methods Simple random: Stratified random: Cluster sampling: Experiment: Experimental units:
2 Experimental subjects: Observational study: Explanatory variables: Factors: Levels: Treatments: Response variable: Principles of experimental design Control: Randomization: Replication: Blind/double-blind: Placebo effect:
3 Confounding variable: Completely randomized design: Matched pairs design (blocks of size 2): Blocking, blocks, randomized block design: Generalizability of results types of conclusions and scope of inference: Descriptive statistics: Inferential statistics: Categorical data: Numerical data: Discrete numerical data:
4 Continuous numerical data: Univariate, bivariate, and multivariate data: Part 2 Directions: Review the definition and differences between an observational study and an experiment. Then find two articles from a newspaper, magazine, or credible online source. One article must be about an experiment and one must be about an observational study. Then answer the first set of questions regarding the observational study article and the second set of questions regarding the experiment article. If you have any questions on the terminology, refer to your definitions in Part 1. Be sure to record where and when you found the article and attach the articles to this packet. Be prepared to discuss your articles once classes begin. Observational Study Questions: 1) Briefly describe the study. 2) What was the population? 3) Describe the sample. Be sure to indicate the sample size. 4) Is there a confounding factor? If so, describe or explain that factor.
5 5) What was the conclusion of this study? 6) Do you have any concerns associated with this study that you have not addressed in your answers to the questions above? If so, what are they? Experiment Questions: 1) Briefly describe the experiment. 2) What was the response variable? 3) What was the population? 4) Describe the sample. Be sure to indicate the sample size. 5) How were experimental units assigned to treatment groups?
6 6) Was there a placebo group? If not, should there have been one or is there a good reason not to have one? 7) Was the experiment run blind, double blind, or neither? Explain. 8) What were the factors (equivalent to explanatory variables) used in the experiment? 9) Identify the levels of each factor. 10) What was the conclusion of this study? 11) Do you have any concerns associated with this study that you have not addressed in your answers to the questions above? If so, what are they?
7 Part 3 Directions: Watch the following videos. There are also problems to complete on the same page as the videos in order to enhance your understanding, but they are not required. On the following site, watch the videos Graphing Data and Other Types of Graphs Now complete the following problems.

9 Part 4 Directions: Watch the following videos Now complete the following problems. Show work when appropriate. 1. There are 8 people in a room. If everyone shakes everyone else s hand exactly once, how many handshakes occur?
10 2. You have 5 reindeer, Gloopin, Quentin, Prancer, Balthazar, and Rudy, and you want to have 3 fly your sled. You always have your reindeer fly in a single-file line. How many different ways can you arrange your reindeer? 3. You just got a free ticket for a boat ride, and you can bring along 4 friends. Unfortunately, you have 5 friends who want to come along. How many different groups of friends could you take with you? 4. You are given two 6-sided dice to roll. For a given roll, what is the probability that the dice add to 6 or less? 5. A fair 6-sided die is rolled. What is the probability that the result is more than 4?
