3 Day Weekend HW!

If you were out today you must make up your quiz Wednesday or Thursday! You can do so during any free period or after school--the quiz has a 25 minute time limit. Study and come ready to earn an A!
  • After our quiz we took some quick notes on stemplots and created one more stemplot in our notes (with decimals)--you'll see this in one of your homework questions.
Homework:
This weekend I chose some problems from the online version of our textbook (linked to the right) for you to complete. Rather than make you find them, I have compiled all of the questions in the file linked below.

  • First, complete each of the questions (in your notebook or on separate paper).
  • Then, always, CHECK YOUR ANSWERS! 
  • Here's the link to your homework:

On Tuesday in class we'll take a lil' break from our quantitative displays and work with a little probability; then, on Wednesday, we'll get back to the displays and start to write about the histograms/dotplots/stemplots/boxplots we create to "describe a distribution." See you there!

If you have some free time this weekend and still feel rusty about any of the summer stuff put in some work catch up! The stuff we saw on today's quiz will show up on future quizzes and eventually on a unit test! Check the blog posts below to see what you need to review from the summer. 

Have an awesome weekend everyone! Come back well rested and ready to really get into the school routine!

Wednesday HW!

I hope everyone had an awesome first day!

Tonight's HW:
  1. Please complete the "Summer Academy Debrief" worksheet provided in class (or linked below.).
  2. Please grade your homework! What's the point of practicing if I don't check my work? Here's a link to the answer key...

Tomorrow in class we'll get back to our chapter 4 notes about quantitative displays, specifically focusing on dotplots and stemplots. Then we'll start to look at how we describe these distributions (if time permits)....See you there!

Remember, we will have a quiz based (primarily) on what we learned in our summer classes on Friday!
  • EVERYONE is taking this. 
  • If you weren't here for our summer classes it is entirely your responsibility to learn what you missed! Be responsible and take initiative!
    • Check the blog post below for some suggested resources

Summer Recap

To those of you who attended--thank you for your commitment and hard work! I really enjoyed working with you all over the past three days. I am already encouraged and excited for the year ahead!

We will have a quiz based (primarily) on what we learned over the past three days next Friday (8/30).
  • EVERYONE is taking this. If you weren't here for our summer classes it is entirely your responsibility to learn what you missed!

Summer Day 2!

Summer Day 2 Homework:
  • For tonight's homework you should enter all data in L2 or L3; don't delete the stuff in L1, we'll need that again tomorrow!
  • Please complete AND GRADE questions 1-4 on the "Summer Academy Day 2 HW" worksheet provided in class (or below).
  • Question 1 is new stuff--you got this! 
    • How can we find the median here?
    • Think: what is the median? How many data values do we have? 
  • Note that question #2 gives you the xmin (what to start at) and the x-scale (what to count by); be sure to use that given info!
    • Use your notes about creating histograms from class today!
  • Question 3 is also new, but this some calculator stuff...
    • Look at the middle left slide (calculating summary statistics: 1 Var Stats) for some help....
    • OR, google "1 Var Stat using ____" and put your calculator model in the blank
      • For example, google "1 Var Stat using TI 83" or "1 Var Stat using Casio"
  • For question 4 I just want you to make a boxplot with your calculator--ignore the directions about showing work for fences
    • To make a boxplot on your calculator simply enter your data, go to the Stat plot menu, choose the boxplot that shows outliers (the one with the dots), and press ZoomStat
    • Then, press TRACE to transfer the boxplot from your calculator to your paper!
  • Check out this AP Stat Guy Video if you need help with questions 3 and 4 on your calculator!
  • Skip questions 5 and 6.


What did we cover in class today?
  • We started with a warmup that we put in our notes: finding an overall mean given two samples
    • We then discussed this context, multiple choice strategies we could use with this type of problem, and shared a couple different ways to find these types of average
    • Today's warmup: A local statistician surveyed residents and asked how many years they had gone to school, including any time spent at a college/university. The statistician collected two samples, one of men, and one of women. The sample of 48 men had an average of 12.89 years of education; for the sample of 60 women, the average was 14.7 years of education. Find the overall mean (average) years of education for all of the people surveyed.
  • Then we looked at last night's homework and addressed any questions
    • In our notes:
      • Percentile: the % of data that falls below a given value
  • On to histograms...
    • First, we created a histogram completely "by hand" using our Olympic medals data, and took some notes on the steps for creating a histogram
    • Then we went back and learned how to create the same histogram using our graphing calculator to be more efficient
  • Finally, we wrapped up class by (quickly) creating a boxplot that shows outliers with our graphing calculators (in sessions B and C only)

Summer Academy Day 1!

Summer Day 1 Homework:
  • Please complete AND GRADE questions 1, 2, and 5 on the "Day 1 HW" worksheet provided in class (or linked below).
  • Question 1 is getting us comfortable with some reading and writing in Statistics....
    • You don't need to write complete sentences, just answer each question fully!
    • Tip: always copy the wording/context directly out of the question (if possible)!
  • Questions 4 and 5 are not things we covered in class--it's your job to try to figure this out! Good luck!

What did we cover in class today?
  • We started with a multiple choice SAT Warmup... 
  • Then we got into some more direct notes:
    • What is data?
    • What are the two types of data?
    • What graphs/displays and summary statistics do we use with categorical data?
    • What graphs/displays and summary statistics do we use with quantitative data?
  • Tomorrow we will first discuss the homework, then we will focus on creating histograms and boxplots--see you there!
