6-4 Review for the test on Tuesday and for the statistics portion of the final. Some time to do make-up work for those that needed.
6-2 Time to begin reviewing for the test next week on compound events, permutations, and combinations. Some had time to do make-up work.
No homework assignment, but students have review sheets for the test and the final that they will have time to work on in class on Friday.
5-20 Reviewed the addition principle, we will retake that portion of the quiz on Monday. The quiz on permutations and combinations will be Wednesday during the second part of class. Then, we explored the counterintuitive nature of the "Monty Hall" problem.
No homework but you can still get credit for finishing the 6-7 worksheet and the combinations worksheet.
5-18 Reviewed for the quiz and after the quiz worked on the 6-7 worksheet because it practices both permutations and combinations.
Assignment: finish both sides.
5-14 Alert! quiz next class on multiplying probabilities and the addition principle. review the worksheets "bad pig" for multiplying probabilities of independent events, "bad guys" worksheet for multiplying probabilities of dependent events, and the addition principle packet and practice worksheet.
Moving on today to combinations.
Assignment: worksheet "Times Square" to practice for the quiz, and finish the front of the combinations worksheet. (remember to use parentheses if putting the whole formula in the calculator at once.
5-12 The addition principle in it's 3 forms, on to permutations.
Assignment: Permutations worksheet entirely.
5-10 Reviewing for the test, taking the test, reading a packet on the addition principle after.
Assignment: on the back page of the packet: 5-40 to 5-44, 5-46 to 5-48
Alert Test Monday on pg. 1-35. What was on the 2 quizzes and tree diagrams.
5-6 We worked on using the multiplication principle to find the number of outcomes if more than 1 event occurs. Then we extended that idea to find the probability of more than 1 event occurring--also by multiplying. Plenty of practice on that on the Bad Pig worksheet. If the first event that occurs changes the probability of the second event, then they're dependent, and you need to alter the 2nd fraction before multiplying. Practice on that on the Bad Guys worksheet. The information is on pg. 40-41 if your notes aren't helping enough.
Assignment: Finish the 2 worksheets and study for the test pg. 1-35, practice tree diagrams. Multiplying probabilities isn't on this test.
5-4 Some time before the quiz to review, some time after to work on tree diagrams.
Assignment: read pg. 36, worksheet counting outcomes front and back, Application 26 pg. 36:1-3
Alert! As you saw on the board, there is a quiz on sections III and IV pgs. 19-30 on Tuesday: mostly theoretical probability, but also complementary events and odds.
4-30 Next we'll be finding the probabilities of compound events, such as flipping 2 coins as we did in class. One of the ways of finding all the possible outcomes is to use a tree diagram.
Assignment: On the application 24 worksheet complete App. 24, (completing the tree diagram includes listing all possible outcomes) Make a tree diagram of flipping 3 coins, and #8 includes completing the table and answering the questions on pg. 35 in the book.
4-28 We reviewed experimental probability before the quiz on sections I and II. After the quiz we had a few notes from pg. 27-28 on complementary events and odds.
Assignment: on the Spins worksheet: all questions except the ones to do with odds: 1-6, 9)a and b, 10)a, 11)a. You can do the odds ones if you think you understand that last thing we talked about in class. Some students have make up assignments they can still do for credit. I gave out copies of powerschool so you would have a list.
4-26: Class with a substitute so quiz moved to Wednesday. App. 13 and 14 and the tiremaker/Gigi worksheet. Some need to make up at least part of the homework and classwork assignments.
4-22: We used App. 5 with tossing a die to compare experimental and theoretical probability. Notes on answering theoretical probability questions.
Assignment: App. 18 and App. 19. Notice you can do App. 18 without actually drawing chips. King's Birthday/girl rock worksheet both sides.
4-20 Notice: Quiz on Monday 4-26 on I and II, pg. 1-18
Today we practiced reading charts to determine relative frequencies and experimental probabilities, even if you have to change the denominator. We are still having trouble reading the type of chart on pg. 12 and 13. So review your work there, because there will be one on the quiz.
Assignment: Finish the worksheet on App. 10 including the 9 questions on the back.
4-9 Open notes entry slip on experimental probability. How to answer experimental probability questions and a worksheet to practice: "Relative frequency/Experimental probability" in class. App. 4 and App. 7 in class.
4-7 Notes on beginning probability and comparing probabilities from pg. 2. Notes on experimental probability and tossing coins in App. 2. Notes on relative frequency.
Assignment: App. 1 and App. 3 in the probability book.
4-5 Our last topic in statistics: a way to use the medians of small sets of data to try to show general trends of data rather than zigzagging extremes called smoothing.
First assignment in 4th quarter. On the copy of App. 37, make a 4th column for the difference (subtract) between verbal and math scores. Then make a 5th column for the smoothed values. On the copy of the plot of the differences, plot your smoothed values and connect the points. Notice how much less zigzagging of data points shows the trend more clearly?

3-31 Hope you're enjoying our "snow day!" I will not see you in class until after grades close, so if you didn't hand in your project on Monday, bring it to me or leave it on my desk in the math office tomorrow WITHOUT FAIL. You will only lose the original 10 points for being 1 class late. I will be in Mr. Ellis' room E block, Mr. Viv's F block, and Mrs. Coulomb's H block. I will be in Mr. Ellis' or Mr. Basset's after school. If you have any other assignments to be made up because of recent absences, you may bring them.
The following students please see me during or after school on Thursday (if you leave it until Monday it may be too late):
Zack D.: you missed a boxplot question on your test, it will only take a few minutes, Josh: you needed to make up the quiz on 5-number summary and boxplots so it won't be a zero, Meg, Zack P. and Marc: unfinished tests, Nileen: bring the quiz you said you hadn't finished and I will give you a few new questions.
3-29 sub today, classwork on boxpplots and median-median line.
Assignment: read pg. 149-150, pg. 150: 1,4,5; Application 37 pg. 154-156: 1-9,11. For the graph in #6, use the same horizontal scale as the plot on pg. 155, for the vertical scale use 25 to 55. Please use graph paper for an accurate plot.
3-23 (for the record) We have drawn a line on a scatterplot to approximate the trend of the data. Now we look at specific lines such as the y=x line. pg. 112-113 #1-7. Time in class to finish the test, work on your project due 3-29, or begin the homework.
Assignment: Home run leader remix worksheet on the y=x line.
3-19 (for the record) Test today on single variable plots.
no new assignment.
3-17 We reviewed so much today that we've decided to have the test on 1-variable plots on Friday, while it's fresh in our minds. It covers percents and pgs. 1-86. Then some time to work on homework assignments and our take-home projects. I will be checking how much you have already completed on Tuesday March 23, so that you are well on your way to finishing by March 29th.
Assignment: App. 26 pg. 106-107: 1-7; App. 27 pg. 108-109: 1-5.
3-15 assignment: the scatterplots side of the worksheet. If you see an association, try to draw a trend line. We will have more class time on the take-home project, due 3-29, but feel free to spend time at home early rather than wait until next week.
3-5 Learning to calculate whether or not extreme values are outliers involves finding the quartiles to calculate the interquartile range. Then we multiply that by 1.5 and add it to both ends of the interquartile range, we get boundaries for what we would consider an extreme value versus what we would consider an outlier. Next Tuesday we will make box plots, which will complete our work on 1-variable data. Thursday we will have a quiz on the 5-number summary and box plots, and review for the test.
Assignment: pg. 62: #3 (the data is on pg. 63); read pg. 64-66, Pg. 66 do #1-5 and 8
3-3 Quiz today on Stem and leaf and mean/median. Time to complete App. 12 and get ready to evaluate outliers.
Assignment: For EACH of the sets of television show ratings data on the App. 12 worksheet, complete a table with the following 6 headings:
1. IQR(that's upper quartile minus lower quartile)
2. Q3 + IQR (that's upper quartile plus the IQR you found in #1)
3. Q1-IQR (that's Lower quartile minus the IQR you found in #1)
4. 1.5xIQR (that's 1.5 times the IQR you found in #1)
5. Q3+(1.5xIQR) (that's upper quartile plus the IQR product you found in #4)
6. Q1-1.5xIQR ( that's Lower quartile minus the IQR product you found in #4). We're looking at a formula for determining whether an extreme value is an outlier based on how spread out the data already is.
3-1 We moved on from median to quartiles and the 5-number summary to describe a data set. Quiz on Wednesday on Stem and leaf--see your printed notes from the last 2 classes, and mean and median.
Assignment: Pg. 54 #2-9, and Appl. 12 from the worksheet with the data filled in. And study for the quiz.
