Stat 1000: Assignment 6 Tips (Distance/Online Sections)
Published: Wed, 02/13/13
My tips for Assignment 6 are coming below, but first a couple of announcements.
Please note that my second two-day review seminar for
Stat 1000 will be on Saturday, Mar. 9 and Sunday, Mar. 10, in room 100 St. Paul's College,
from 9 am to 6 pm each day. This seminar will cover the lessons in Volume 2 of my book.

Did you read my Tips on what kind of calculator you should get?
Did you miss my Tips for Assignment 5?
If you are taking the course by Classroom Lecture (Sections A01, A02, etc.), I will send tips for Assignment 6 once it is posted.
Tips for Assignment 6 (Distance/Online Sections D01, D02, D03, etc.)
Don't have my book? You can download a free sample containing Lesson 1 at my website here:
Study Lesson 3: Designing Samples and Experiments in
the current edition of my book, if you have it, to prepare for this
assignment. Note that, in older editions of my study book, this was Lesson 4.
Thankfully, there is no JMP needed for this stuff.
Question 1
Good luck guessing the exact word they want. Note that sometimes it will be more than one word you have to put in the blank.
Question 2
Note non-response rate is just
the total number of non-responses divided by the total number of emails
sent out. Response rate would be the total number of responses divided
by the total number of emails sent out. Make sure you compute the non-response rate and not the response rate by mistake. These rates could be changed
into percentages but the question wants them left as decimals. DO NOT STATE YOUR ANSWER AS A PERCENTAGE.
Question 3
You will need Table B to help answer this question. That is in the textbook or can be downloaded from the
resources section of Stats Portal. Here is a link where you can
download the table immediately, if you prefer:
When they ask in part a, "how
would you assign labels?" they merely mean what numbers would you
assign
to the units. They merely want you to explain how many digits each
number you assign will have. Like my example at the start of Lesson 3,
where I have 700 people in my population, so I assign them the numbers
001, 002, up to 700. The largest number
in the population dictates how you will assign numbers (labels).
Question 4
When they ask you what the number in bold is, all they want you to say is that it is either a parameter or a statistic.
I define what those two things are at the start of Lesson 4 (Density Curves and the Normal Distribution) in my study
book (lesson 2 if you have an older edition). Parameters describe populations, statistics describe samples.
Question 5
A sample survey is just that, a survey where you are asked
to
answer a bunch of questions. For example, opinion polls are sample
surveys. I tell you what experiments and
observational studies are in Lesson 3, question 6. Many sample surveys
can also be observational studies. That's what they mean by
"observational study that is not a sample survey." In other words, if
they are just conducting an opinion poll or the like, say it is a sample
survey, even if you think it is also an observational study. If they have a goal in mind where they believe one or more factors can be used to explain a particular response, they must be conducting either an observational study or an experiment.
