Statistics - You will have a Schoology assessment due Wednesday night. Please remember that the assignment is supposed to be your own work. Using someone else's answers is cheating and defeats the purpose of this practice opportunity. Your test scores will reflect your lack of practice.

APCS- Complete the FREE Codecademy.com/learn/learn-java course. Most of it will be review, but you will be coached through arraylists and Boolean logic at a very basic level. Do not pay for the optional quizzes or tests.

AP Statistics - Thank you for the great questions in class today. We covered using the standard Normal table in class today. If you missed class, you are still responsible for learning how to use the table, so read Chapter 2 of your textbook. As I told you last Friday, tonight's assignment is on using the Normal distribution (normalcdf and invNorm in your calculator).

AP Computer Science - We finished the explanations of the activity from Friday in class today. Tomorrow we apply the concepts of *passed by value* and passed by reference to methods. Use your textbook or the Georgia Tech textbook to catch up if you missed something.

AP Statistics - You have a homework assignment on Schoology due before midnight Sunday night. You will need the textbook for support. The Chapter 1 test will be Wednesday the 16th. The study session for the test will be Sunday 2-4 in the outside classroom unless the weather is icky, when we will move to room 313. Watch Twitter for more info.

AP Computer Science - Do the online pretest from the GT online textbook. The questions will be similar to the questions you will see on the SLO, unit tests, and the AP exam.

REGISTRATION OPENS ON AUGUST 15th for the AP exams. Let's plan for success.

AP Statistics - we've been covering stem and leaf, split stem and leaf, and boxplots. Please answer the question on the handout (Problem #4 from last year's AP exam) on your own paper. [Whenever I hand out copies of the questions provided by College Board you will answer on your own paper or in your own notebook. There will not be sufficient space to answer between the parts of the question.]

AP Computer Science - We've been converting numbers between bases. (10 and 16, primarily, with a touch of base 2 so far). Please complete the handout on integer division for Thursday's class. BTW, this color is DFFFBF in hexadecimal.

AP Statistics: There is a Schoology quizlet available online for you. The deadline is midnight tonight. We have begun Chapter 1, a unit on descriptive statistics and graphing. Today one group of students led us through a simulation for one variable and graphing the results. We used a dotplot and discussed the advantages of dotplots over histograms and the disadvantages as well. Tomorrow we will learn about stem and leaf plots.

AP Computer Science: We learned about integer division today. For instance, in integer division, 13/5 = 2. The remainder 13%5 = 3. If the discussion was not clear from the activity with cards, please see me before school on Tuesday or Wednesday to get this cleared up. Then we played with the Code-a-pillar. Good job, programmers.

Computer Science--

Define the function TRUNCATE as the operation of removing the decimal part of a positive real number. So if the number consists of the whole number part W plus the decimal part D (where 0<=d<1), then TRUNCATE (W+D) = W, or TRUNCATE(98.6) = 98 and TRUNCATE(3.0000002) = 3.

Sixth period: Create an algorithm (a set of steps) using the TRUNCATE function and no other fancy function to perform rounding to the nearest whole number when given a positive real number.

Fifth period: Create an algorithm using the TRUNCATE function and no other fancy function to round positive real numbers to the nearest multiple of 5, like 98.6--> 100 and 96.6-->95.

How will you know if your answer is correct? If it works for every positive real number, then it works, but it is impossible to check with ALL real numbers. What do we do? Check it with a bunch of extreme or complicated cases that have different characteristics.

AP Statistics -- You may request access to the Schoology pages using your existing account, or you can get the admission code in class tomorrow. Please dress appropriately tomorrow for doing moderately active labs.

Please return signed receipts for syllabi this week.
