BIO500 week 1 dq 1 & dq 2 latest 2016 may
dq 1
Search for 2 or 3 SPSS tutorials to help you learn how to use
SPSS. Answer the following about the websites. Provide the website for the 2 or
3 tutorials that you found on SPSS? What specific things were you searching for
in these tutorials? What did you like or dislike about the tutorials? What did
you find the most useful in these tutorials?
dq 2
This course is designed to provide you with the knowledge and
skills in application, evaluation, analysis, and interpretation of
biostatistical data used to inform public health programs, policy, and
practice. View the online video, “Careers in Biostatistics.” The
video describes the education that a professional biostatistician receives at
the University of North Carolina. More than likely you will be working with
professional biostatisticians. Why is it important for you to take this course
in biostatistics?
GC BIO500 week 2 dq 1 & dq 2 latest 2016 may
dq 1
Compare a minimum of three statistical packages that are available
to statisticians and/or students of statistics.
dq 2
Assume you are working for a local
public health organization at the state level. Your team wants to develop a
program to prepare for a possible pandemic that is spreading worldwide. View,
“Laurie Garrett on Lessons From the 1918 Flu.” How could knowledge of
the course objectives help you make recommendations to your organization?

dq 1
It is time to relate the rules and concepts of probability to the
practice of statistics and experimentation. Sampling distributions provide the
link between probabilities and data. Recall that the sum of the probabilities
of all possible outcomes for a certain event must equal one. Because the
variables representing or describing a certain event can take on a range of
values, the frequency of each of those values forms a distribution of possible
outcomes, each with its own probability of occurrence. View “Central Limit
Theorem” (media piece). What is the significance of the frequency
histogram illustrated by dice and numbers in “Dice Combination?” How
does this relate to the central limit theorem provided in the media? Roll the
dice, what were your odds? HINT: Click on Dice Combination in the media. If you
roll the dice, you have to count the total number of two dice. There are two
ways to check on your results (Refer to the instructions by clicking
Instructions); click on the dice combinations and odds given in the frequency
histogram and the table or click the red bar at the right side of the media
piece. Explore the basic principle of probability through this media piece.
Utilize the quiz to ensure that you understand these basic principles. What is
the significance of probability in judgment and decision making in important
aspects of health care? Explain your response with an applicable example.
dq 2
For the public health industry, describe some examples of a random
variable.
GC BIO500 week 4 dq 1 & dq 2 latest 2016 may
dq 1
Explain the important points of the central limit theorem.
dq 2
View “Seth Berkley: HIV and Flu–The Vaccine Strategy.”
What are some of the tools in this course that epidemiologists use
to perform their work?
GC BIO500 week 5 dq 1 & dq 2 latest 2016 may
dq 1
As a health care professional in public health, describe some
examples of where hypothesis testing would be used.
dq 2

This course is designed to provide you the knowledge and skills in
application, evaluation, analysis, and interpretation of biostatistical data
used to inform public health programs, policy, and practice. Elizabeth Pisani
is an epidemiologist in public health and has a message about the role that
politics has on the use of the data. View “Elizabeth Pisani: Sex, Drugs
and HIV – Let’s Get Rational.” Do you agree or disagree with Pisani’s
message about the role of politics in public health?
GC BIO500 week 6 dq 1 & dq 2 latest 2016 may
dq 1
As a health care professional in public health, compare when you
would use hypothesis testing and when you would use regression.
dq 2
If a regression line (linear regression line) is said to
“fit” the data presented in a scatter plot, what relation is
minimized between the observed data, y, and the predicted output for the
regression line?

GC BIO500 week 7 dq 1 & dq 2 latest 2016 may
dq 1
As a health care professional in public health, describe some
examples that demonstrate the importance of interaction of variables in a
two-way analysis of variance.
dq 2
Explain why computing a variance of several numbers is like
analyzing their differences.

GC BIO500 week 8 dq 1 & dq 2 latest 2016 may

dq 1
Discuss the differences between parametric and nonparametric
tests.
dq 2

Discuss the advantages of nonparametric tests.
