Tomorrow we'll start class with our first (multiple choice) vocab quiz (chapter 2)--your first priority tonight is to prepare yourself to earn an A! The vocab list is below.
- All or some of these words will be on your vocab quiz, which is entirely multiple choice
- You will be given the word and asked to choose the best definition, or given the definition and must choose the correct term
- Data
- Categorical Data/Variable
- Quantitative Data/Variable
- statistic(s)
- Statistics
- relative (just means to use %'s!)
- What statistics are used to summarize quantitative data?
- Which are measures of center? Of spread?
- What graphical displays are used with quantitative data?
- What statistic is used to summarize categorical data?
- What graphical displays are used with categorical data?
- Response variable(s): this is what we are measuring or recording in a study
- Experiment
- (Sample) Survey
- Observational Study
The following homework assignment is due (and will be checked) on Friday, but get a head start tonight!
- Period A I will check last night's homework tomorrow since I did not do so today
- Page 39: 19
- Some probability review here--use your notes from day 3 of our summer academy!
- Remember to look at the "of ____" to determine your denominator...
- For example, if we were asked what percent of waitlisted students are black/hispanic, then we know our denominator is 300, or the total number waitlisted ("of waitlisted")
- Pages 65-71: 9, 11, 17, 19a, 33c
- For 9b don't worry about the answer in the back of the book or describing shape...we'll learn that...
- For this question (9b), I want you to write a few sentences...
- Write a sentence providing the median size (in acres) of the 36 vineyards and the range in sizes of vineyards
- Then, write a sentence describing what this graph tells us about the sizes of these 36 vineyards--what sizes are most vineyards? "Most vineyards are _________.
- Comment on any "unusual features--were any vineyards unusually large or small? What size?
- For 11b just describe the center and spread--use your calculator to find the 1 var stats
- Center: provide the mean and median
- Write these in a complete sentence: "The mean gas price for 16 gas stations in Ithaca, NY is ___ and the median price is ___."
- Spread: provide range, IQR, and standard deviation (Sx)
- Write these in a complete sentence: "The range of gas prices for 16 gas stations in Ithaca, NY is ____, with an IQR of ___, and a standard deviation of _____."
- For 11c look at your stemplot--what unusual feature do you notice?
- For 17 only create the stemplot.
- For 33c you want to determine if there are any outliers for the # of assaults (per 1000) and then for the # killed-injured (per 1000)...
- This is two different problems--first use your calculator and the 1 Var Stats to find Q1 and Q3 for the # assaults, then calculate the fences to see if there are outliers
- Repeat this process for the # killed-injured
Tomorrow in class we'll finish up our notes on "creating displays" and start to transition to some notes on describing them! See you there!
