Homework

8/28 Get syllabus filled out and signed and re-__#|read__ chapter three

For the __#|homework__ on 8/29 do we need to summarize chapter 3 in notes? Or just reread it? Thanks!

8/30 Read chapter 4 along with __#|problems__ 16, 24, 26, 28, 30 on page 51.

What would you label the axis' on #28 when you had to draw a histogram?

How about __#|Cholesterol__......Smoker's __#|Cholesterol__......Nonsmoker's Cholesterol I said the non-smoker's graph was more uniform since it was almost evenly flat.

What numbers would you put in the x and y axis? for #28

How do you know which method of displaying quantitative data is best? Also can you please thoroughly go over how to make these graphs; I have no problem __#|reading__ them.


 * 1) 30 Says to create a back-to-back stem and leaf plot.Chapter 4 did little to explain this, so how do you make one when the data is in decimals like this?

9/4 Page 30 #11,14,16,21 and Page 50 #5,7,13 No Assessment __#|next__ class

What is the difference between marginal and conditional distribution? I'm still a litttttleee confused on that.... a conditional distribution is more specific, like if there's a specific condition for a variable then its conditional. but a marginal distribution refers to the whole graph and its variables.

How do you Find the marginal distribution? I know a distribution is all the possible categories and how frequently they occur and a marginal distribution is talking about a variable. i don't fully understand it either

From Mrs. Clark: This is correct. For the marginal distribution, the denominator is the grand total. For the conditional distribution, the denominator is either the bottom or side totals. If it says "within each age group", then the totals of the age groups are what goes in the denominators.

9/6 page 50 #6, 10, 11, 15 and 30. Also complete chapter 4 study guide and prepare for the __#|quiz__ on chapter 3.

On the study guide for chapter 4, it asks for another way to re-express skewed data, I'm not really sure how to answer this one.

Is the chapter 4 quiz the class after we get the study guide? Or two?

I'm not entirely sure about how to explain the distribution of a quantitative variable. Can anyone give me a hint on what this questoin (number one on the chapter 4 study guide) is referring to?

Re-expressing the skewed data is talking about that section where it said to take the log or the square root of the data I think. And the distribution of a quantitative variable is asking for the shape-center-spread of the graph as well as any odd features. Does anyone know how to make a dotplot on the calculator?

how do you draw the time plot for #15?

Can we go over #3 on the study guide? If you are referring to the chapter 5 study guide, the range is calculated simply by subtracting the minimum value of a data set from its maximum value.

9/10 I was wondering for the key concepts, on this wiki, if we are suposed to post their definitions in our own words or by how the books states it?

when is the chapter 5 study guide due for B days?
