AP STATISTICS SUMMER ASSIGNMENT (2020)Welcome to AP Statistics! I am looking forward to having you in class in the fall. Inorder to be ready to hit the ground running in September, you have some preliminarywork (Chapter 1 in the textbook plus 3 supplemental problems ) to complete on your own.The assignment will be collected the first day of class (Monday, 8/31/20, OR wheneverthat ends up being) with a 5 point BONUS for turning in on or before 3PM onThursday, 8/27/20 (emailed to me, cburke@hinghamschools.org , only scanned “pdf”formats but NOT “picture” formats, please, or in my HHS mailbox, again by 3PM thatday). It will be graded (as a test grade) for completion, correction (where possible), andaccuracy. Please take this assignment seriously, as we will use the material presented inthe first chapter throughout the entire course. Though you may email me with questions,what you turn in is to be YOUR OWN WORK, and any indication of identicalcommentary or presentation will be treated as a cheating incident. TEN POINTS WILLBE DEDUCTED FROM THE SUMMER ASSIGNMENT GRADE EVERY DAY IT ISLATE. Some important information follows:0) YOU WILL NEED TO REGISTER FOR ACCESS TO THE 5 TH EDITIONTEXTBOOK TO COMPLETE THIS ASSIGNMENT, using the followinglink AND the ACTIVATION CODE given to you by ME (or the main Unauthenticated?TargetURL 9851401) Please read the textbook carefully. This course is based on vocabulary andunderstanding of concepts (not just calculations) presented in the text, so it shouldbe read and reread to ensure maximum comprehension. If you only skim or skipreading altogether, you will probably miss some detail needed to correctly answera question. There are periodic checkpoints (“Check for Understanding”) withanswers AVAILABLE BY CLICKING A TAB RIGHT WHERE QUESTIONAPPEARS that can help you with similar problems you will be turning in as partof the summer assignment.2) Use the answers BY CLICKING THE TAB WHERE QUESTIONAPPEARS to odd numbered questions and correct (if necessary) youroriginal attempts. You have been assigned only odd-numbered questions (seelist on next page) from the book, so it is expected that you will self-check ( andcorrect ) as part of completing these problems. IN FACT, PART OF THE“COMPLETION” GRADE IS EVIDENCE OF THIS SELF-CORRECTION( correct answers being shown! ) DONE FOR ALL OF THE BOOKPROBLEMS.3) Graphs (any visual display of data) SHOULD BE DONE ON GRAPHPAPER IF THE SCALE IS SIGNIFICANT. Please let me know if you need
graph paper (a few “snippets” of graph paper are provided for your convenience).Points will be deducted for scaled graphs not done on graph paper.4) This is as much a writing course as it is a math course. Explaining in completethoughts (sentences) is required on this assignment and throughout the course. Often,questions will require you to comment on what your graph tells you (so again, writeclearly and in complete sentences when applicable). THE LAST TWO PAGES OFTHIS HANDOUT ADDRESS THE FIRST TWO “BIG IDEAS” OF THECOURSE (please tear off and retain as notes!!). APS Big Idea #0 addresses acouple of common question prompts for one of the most unique types of questionsappearing on our AP exam in May, the “free response question” (will be the mainfocus of our first week in the course, in fact!). APS Big Idea #1 outlines a pneumonicdevice that might help you to remember the 4 major areas that need to be addressedwhen asked to describe and/or compare your data ( “SOCS” , forgetting any one canbe a critical omission ). Also, DON’T JUST SPOUT #’s, USE #’s IN CONTEXT(what they mean to that particular problem using appropriate units like “feet” or “ ”,for example).5) You may want to retain a copy of your summer assignment (for yourself).We will be going over the assignment during the first week of class, but you may nothave access to your own submitted work the first few days of class.6) You will need to have a TI-83/84 the first week of class (though having oneshould not be necessary to complete the summer assignment).7) WE WILL HAVE AT LEAST ONE QUIZ (perhaps surprise!) AND A TESTON THE MATERIAL COVERED IN CHAPTER ONE WITHIN ONE WEEKOF THE START OF SCHOOL.ASSIGNED PROBLEMS (to be handed in first day of class, NO EXCEPTIONS!!!)(Starting page for problem groups is given for your convenience)1) p. 6 ( 1 – 7 odd )2) p. 20 ( 9, 15 – 33 odd)3) p. 41 ( 37 – 41 odd, 45 – 51 odd, 59, 63 - 73 odd )4) p. 69 ( 79 – 109 odd, NOT 87, 103, 105 )5) Additional problems # A1 – A3 (attached)Remember, don’t start the assignment too late, or you willfeel the effects in grade form and in understanding thenecessary concepts for the very first week of AP Statistics!Enjoy your summer, Mr. Burke ( additional problems follow, next3 pages )

APS BIG IDEA #0 -- Common Question Prompts on “Free Response”Here is a summary of how you should approach these problem types:
APS BIG IDEA #1 -- “SOCS” for Describing/Comparing Distributions1) S HAPE ( comparing 2 distributions means how similar/different) a) Can be approximately symmetric, skewed left, or skewed right(or bimodal, trimodal, etc.).b) Remember to (mentally) remove outliers before commenting onthe shape (only!), as outliers should not be the sole reason for askew (for example, it’s better to say “fairly symmetric (withoutthe high outlier)” than “skewed right (because of highoutlier)”).2) O UTLIERS ( only need to describe if o bvious or a sked to calculate )a) Math MUST be shown even if there are no outliers (it’s theonly way to judge you ever formally checked!)(Remember:Q3 1.5IQR and Q1-1.5IQR!)b) Always use modified box plots (showing outliers) over regularboxplots (because outliers are shown!)3) C ENTER ( comparing 2 distributions means which is bigger )a) Address the center of your data early (as an “average”tendency) and specifically in your analysis (graphs and numbersummaries don’t speak for themselves!).b) Don’t just state your mean/median; tell what it says about thecentral tendencies of your data (in context, so using UNITS!).c) When (one or more sets of) the data is skewed or has outliers,don’t use the mean for center; use the median (for both).4) S PREAD ( comparing 2 distributions means which is bigger )a) Don’t just state your 5-number summary (or how they werecalculated), but use these numbers to discuss what it meansabout your data IN THE CONTEXT OF THE PROBLEMANALYSIS.b) Include statements when there are notable GAPS in the data,stating where those occur AND locations of peaks, when thereare obvious multiple ones.c) Q1 and Q3 are numbers, not ranges, so make this distinction inyour discussion (for example, say “between Q3 and the max”,“between Q1 and the median”, etc.).d) For relatively symmetric data, you can use standard deviation(spread) but always with the mean (center); for (one or moresets of) skewed/outliered data, it’s better to use the IQR withthe median for spread and center (of ALL), respectively.
