Weekend HW = Take Home Quiz!!!!

This weekend, please complete the chapter 5 take home quiz! If you were out or you lost yours, you can find it uploaded under the "Classroom Powerpoints and Assignments" link on the right! (Choose the "Powerpoints and Assignments" link, then "Unit 1 Resources")

Be sure to have this on Monday! A zero would have a major negative impact on your grade!

Next week we'll continue to work with z-scores and the Normal model--lots of number and math and graphing calculator stuff! I love it!

It's looking like our plan for testing has changed.....here's what I'm thinking...

• Thursday 10/6: Unit 1 Vocab Test (chapters 2 - 6)
• Due Tuesday, 10/11: Unit 1 Take Home Exam (chapters 2-6)
• Wednesday, 10/12: In-class exam: Unit 1!
• This will give us three more test grades in the gradebook--which is important, because tests make up the largest proportion of our grade, so we want lots of opportunities to earn those points!

Have an awesome weekend! Come back ready to work hard through your four day week next week! See you Monday!

Oh, and if you're feeling like getting ahead, here's Monday night's homework (you can do some of it already, but not all of it...)...

Page 123-128: 5, 7, 9, 17, 23

• Questions 5,7, and 9 are all based on using z-scores--so you can do these already! I'd recommend doing so if you have the time so you just have to worry about 17 and 23 on Monday night!
• If you'd like to do it all, you have to apply the Empirical Rule or the 68/95/99.7 rule for 17 and 23!
• Read about this rule on page 109, then look at the "working with the 68/95/99.7 rule" example on page 110!
• OR, do some googling--look up some videos or practice about the Empirical or 68/95/99.7 rule!
• OR, watch a video about this rule from the AP Stats Guy or from the videos aligned with our book!
• How about this counts as some extra credit!
• If you do 5, 7, and 9 for Monday I will give you an extra homework point! (each homework counts as 2 points, so an extra 1 point is like half a homework grade)
• If you also look up how to do and try 17 and 23 I will give you another extra credit point!
• So, if you do all of Monday's homework this weekend and show me on Monday you'll get an extra credit homework grade to make up a past zero or just further boost your homework average!

Thursday and Weekend HW!

Tonight, answer the following questions...this will help us to drive the z-score formula in class tomorrow!

The SAT's are designed to have a mean of (roughly) 500 for one section of the test, with a standard deviation of 100.

a.) Consider an SAT score of 610 on one section. How many standard deviations above the mean is a score of 610?

• Do some math! Your final answer should be a number!

b.) Now, consider an SAT score of 390 on one section. How many standard deviations below the mean is a score of 390?

• Do some math! Your final answer should be a number!

c.) Examine the math you did to answer questions (a) and (b). Your challenge is to consider your work in (a) and (b) and translate your ideas into a generic formula.

• Let "x" represent a data value (or the given SAT score, like 610 or 390).
• Let "x-bar" represent the mean
• Let "Sx" represent the standard deviation.
• Write an equation using these three variables to find "the number of standard deviations above or below the mean." 

Weekend HW:

This weekend you have a chapter 5 take home quiz! This is a major quiz grade, so take your time and work diligently! This is like 3 vocab quizzes combined so be sure to use your notes and get an A!

The quiz is uploaded under our classroom resources link if you lost your copy!

Weekend HW:

This weekend you have a chapter 5 take home quiz! This is a major quiz grade, so take your time and work diligently! This is like 4 vocab quizzes combined so be sure to use your notes and get an A!

When's Day HW!

Tonight please complete the following in your textbook:

Page 123: 1, 3, 11, 13

Also, if you did not do the extra credit assignment last night you can do so tonight--but this is your last chance! Get on it!

Tomorrow we'll get back into our chapter 6 notes!

We will not have a quiz on chapter 5 in class this week--instead, I think I'm going to give it to you as a take home quiz this weekend!

Tuesday HW!

Tonight, please complete part (a) of the 2012 AP Free Response provided in class (or below!)

• Remember, we haven't learned how to do part b yet, so skip that!
• Want some extra credit? Score part A of your response using the online rubric--follow the instructions below! (this will count as an extra credit homework grade)
• Record a score of E, P, or I for section (sections 1,2,3 in the rubric apply to part a)
• Then next to each score (for each section) write at least 2 bullets explaining what you did well, or what you would've needed to do correctly to earn an E!
• Reference both the rubric AND the sample answer provided! 
• Your scoring explanations must be THOROUGH and DETAILED to earn the extra credit!
• Here is the link for the 2012 scoring rubric! Scroll down to #3! Click me!

Tomorrow in class it's back to chapter 6! See you there!

Monday HW!

Tonight, please determine the 5 number summary for the ogive regarding "heights," and then use this to create a boxplot.

• Even though the values on the y-axis are written as decimals, these still represent the "cumulative frequency" or "percentile" and can be written as percentages (multiply by 100 to convert to a %)
• When we create the boxplot we will only have the 5 number summary--this means that if the minimum is a low outlier, we will not be able to draw an arm on the left side of the boxplot; similarly, if the max is a high outlier, we will not be able to draw the arm on the right side of the boxplot!

We will also have our chapter 5 vocab quiz to start class tomorrow! STUDY! Here's the vocab list: (use the glossary at the end of chapter 4 and the end of chapter 5 for definitions!)

• Center
• Spread
• Mean
• Median
• Midrange
• Know the (4) measures of center: mean, median, mode, midrange
• Standard Deviation (Sx)
• Range
• Interquartile Range (IQR)
• Know the (4) measures of spread: range, IQR, standard deviation, and variance
• Percentile
• Know the percentile for each value in the 5 number summary
• Histogram
• Ogive
• Boxplot
• 5 number summary
• "Appropriate summary statistics"--know the table we finished in class!

Weekend HW!

This weekend please complete the "Comparing Boxplots" problem about the heights of self and cross fertilized plants! (on the back of Thursday's comparing boxplots example!)

• First, create two boxplots, one above the other, on the same axis! (parallel boxplots)
• You have to do this by hand because you don't have the entire data set to enter into L1!
• Then, compare the boxplots! Use today's (Thursday's) notes/example as a reference!
• Compare SOCS!
• You should be sure to use comparative language, particularly when comparing "center" and "spread!"
• Be sure to also emphasize the CONTEXT!
• After comparing SOCS, wrap up your comparison with a "generally" statement--generally, which plants were taller? Support this with some percentages!

On Monday we will answer any remaining homework questions (from last night's book work), we'll learn how to read an ogive, and then start chapter 6!

We will have a chapter 5 vocab quiz on Tuesday! 

Until then, enjoy your weekend! Go Giants!
