Text: INTRODUCTION to the PRACTICE of STATISTICS, SEVENTH EDITION, by David S.
Moore and George P. McCabe, W. H. Freeman and Company, New York.
Prerequisites: Graduate Standing.
Statistical Package and Calculator:
Throughout the course students will be required to use SPSS, a computer program, for data
analysis. Student version can be purchased at UTS upon enrollment. Contact UTS at uts.fiu.edu, and
at 305-348-2284. SPSS is also available in computer labs in PC 411, PC 413, PC 414. It is also free
to all students online at https://elabs.fiu.edu. Students will also be expected to be able to perform
the calculations using a calculator as well.
Course Management: We will use Blackboard Learn as the course management system at
https://fiu.blackboard.com/. Lecture notes and assignments will be posted, and grades will be
recorded and tracked on Blackboard.
Topics:
REVIEW OF INFERENCE FOR DISTRIBUTIONS (Sections 7.1 and 7.2)
Inference for the mean of a population: t-tests and matched pairs t-tests; comparing two means ztests and t-tests for independent samples.
REVIEW OF INFERENCE FOR COUNT DATA (Sections 8.1 and 8.2)
Inferences for a single proportion and two proportions.
INFERENCE FOR TWO-WAY TABLES (Sections 9.1 and 9.2)
Two -way tables; Chi-square test of indpendence.
INFERENCE FOR REGRESSION (Sections 10.1, 10.2, and Chapter 11)
Inference procedures for the parameters of the simple linear regression model and of the
multiple regression model. Inference procedures for correlation.
ANALYSIS OF VARIANCE (Sections 12.1, 12.2, and Chapter 13)
One-way analysis of variance with contrasts and multiple comparisons. Two-way ANOVA with
interaction.
ADDITIONAL TOPICS (If time permits, handout will be provided)
Randomized complete block design and additional inference procedures for correlation.

Attendance: You are expected to attend all classes and to arrive on time. If you miss a class, you
are responsible for all material and announcements covered in class on that day. Attendance will
be taken in the form of quizzes, which may occur either at the beginning or the end of lectures. Half
of points of quizzes will be based on attendance, and the other half will be based on performance
of the quizzes. No make-up quizzes will be considered.
Homework: You are allowed to work together on homework assignments, but you need to write
up the solution on your own, so that your homework does not become a copy of another.
Project: You will work in groups for the project. Some possible project problems will be given, but
the problems related to your own research are strongly recommended. The outcome will be
evaluated through a written report and/or an oral presentation.
Exams: The midterm and final exams will be both in class, close-book and close-notes. The
midterm exam will be on 2/19, Wednesday, and the final exam will be on 4/21, Monday, from 5
pm to 7 pm. No make-up exams are considered unless extreme circumstances and documentation
will be required. Also, you must notify me prior to the exam or the day of the exam if you think
your situation merits a make-up. If you miss an exam for a valid reason but do not notify me of
your situation in a timely manner, then you will receive a zero on the exam.
