HW = STUDY!

Tomorrow we will start class with 2 chapter 4 quizzes--vocab and "math." Be ready! Even you absent people will be taking it, no excuses!

Also, many of us should be looking back at last night's homework and re-scoring our free response--I need more detail for you to get full credit!

• You MUST give yourself a score of E, P, or I for each section based on the rubric
• You MUST provide a few notes/bullets explaining what you got that score...
• What was missing? 
• What would you need to add to get an "E?"
• Even if you got an E--what could you have done differently? Or, what could have done to improve your response!
• Check the blog post from yesterday for the homework question/link to the rubric.

Period A--I think I made a mistake with the median for that Old Faithful histogram--sorry Olivia, you were right! Next time you guys yell at me and tell me I messed up! Check it out:

Chapter 4 Vocab List (10 minutes for this section)

• These first two terms are new--center came up today, and a definition of spread is not in your notes--so the definitions are below:
• Center: An attempt to summarize a data set with one number--a "typical value" in a data set.
• Spread: measures how much our data varies, or how tightly our data is clustered around the center; also known as "variability"
• Histogram
• Boxplot
• Dotplot
• Stemplot
• Describe a distribution (what do we describe?)
• Skewed Left
• Skewed Right
• Know how to describe the shape of a distribution given a graph (unimodal, bimodal, uniform, symmetric, skewed left/right)
• Measures of center
• Measures of spread
• All chapter 2 vocab words are fair game: definitely review...
• summary statistics for categorical data
• graphical displays for categorical data
• summary statistics for quantitative data
• graphical displays for quantitative data
• Response Variable

"Math" Section: Graphical Displays and Describing Distributions

• Create a histogram using your calculator (5 min)
• Describe the distribution (5 min)
• Know how to find median, range, sample size, given a histogram--look at the warmup from the first day of our summer academy, or our stamp problem about "lengths of Greek tragedies!"
• Here is a "practice quiz" you can try (there's a second question in addition to the one provided in class):

• And here's an answer keys so you can check your work to study!
