Statistics/Business Statistics (Spring, 2019)
SYLLABUS:
Course & Section Numbers
- MA-157 = Sections 201 (Emmetsburg), 202 (Estherville),
203 (Algona), 204 (Spirit Lake), 205 (Spencer)
- BS-211 = Sections 201 (Emmetsburg), 202 (Estherville),
203 (Algona), 204 (Spirit Lake), 205 (Spencer)
- Statistics and Business Statistics are two numbers for essentially the same course.
Schedule
- Thursday evenings, January 10 – May 9, 2019
- Class is scheduled to run from 5:30 - 9:30pm.
- The course will be taught over the ILCC television system, primarily
originating from the Algona campus.
Description
- CATALOG DESCRIPTION: The use of statistics by the methods of
descriptive and inferential statistics. Both single and bivariate
data are analyzed. Elementary probability and normal probability
distributions are studied along with hypothesis testing, linear
correlation regression analysis and analysis of variance.
- GENERAL DESCRIPTION: In this course you will first learn about
descriptive statistics in one and two variables. You will then use
the basic concepts of probability to understand inferential
statistics. In particular you will learn how to use statistics to
estimate information about a population and how to perform
significance tests using both traditional and non-parametric
statistics.
Credit
Prerequisites
- There are no formal prerequisites for this class.
However, a basic knowledge of algebra will be extremely
useful.
- All students also need to achieve appropriate scores on
one of ILCC's mathematics placement tests.
Transferability
- This is a basic introductory statistics course.
Equivalent courses are offered at almost every college,
and it should transfer freely.
- Many majors have a statistics requirement, and this
course should meet that requirement for most majors.
- Some math and science majors may require a more
formal proof-based course. If you need to transfer this
course and have any questions, contact the college you
plan to attend.
Instructor
Book
- Brase, Charles Henry, and Corinne Pellillo
Brase. Understandable Statistics: Concepts and
Methods. 11th Edition. Stanford, CT: Cengage Learning,
2017.
- The textbook that the fulltime ILCC faculty
have selected is available from the
ILCC bookstore, and it should also be
available online from the publisher and from retailers such as
Amazon.com
or bn.com.
You may also wish to check into e-book editions
and inexpensive rental options online.
- The book will be used for reference in
class, and problems will be assigned from it. If
money is a concern, students are encouraged to
share textbooks.
- Ancillary materials such as the note-taking
guide, solutions manual, and on-line access
subscription are not necessary and will not be
used in this class.
Calculator
- You should have a graphing calculator
designed for statistics for this class.
- The best calculators for this class are
the TI-84 or TI-84+ graphing calculators,
which are available for $75 - $125 in area
stores such as K-Mart, Target, Wal-Mart,
ShopKo, Staples, and OfficeMax, as well as
from the ILCC bookstore. It is assumed you
will have a graphing calculator for the
class. For the purposes of this class, the
TI-84 and TI-84+ are identical.
- The TI-83 or TI-83+ will work
essentially the same as the TI-84 for almost
all of the topics covered in the class. (The
exception is the X2-GOF test.) It
is also generally less expensive.
- Phone apps (such as wabbitemu) are available that emulate
the features of the TI-83 and TI-84. You are
welcome to use these in class or for
assignments, but you may not use the phone
apps on tests.
- ther Texas Instruments graphing
calculators, such as the TI-81, TI-82,
TI-85, or TI-86 are not recommended. They do
not have the statistical features that will
make your problems much easier to do.
- Graphing calculators made by other
companies (H-P, Sharp, etc.) may work. This
is not guaranteed, however, and instructions
in the class will be geared to the Texas
Instruments machines.
Other Supplies
- You will need to take organized
notes almost every week, and you will
want writing materials to do this.
- A small supply of graph paper may be
useful for some problems, but is not
required.
- In addition, you will need to
complete an individual or small group
project. This may require some
additional supplies, depending on what
you choose.
- Many students choose to print out
the online notes and then add to them
during class.
Overall Goals
- Understand the uses of formal
statistics, and apply statistical
methods to solve real-world
problems.
- Describe and apply sampling
procedures.
- Calculate and interpret
descriptive statistics such as
measures of central tendency,
dispersion, and position.
- Understand the basic theory of
probability, and how probability is
applied to statistical problems.
- Use sample statistics to
estimate population parameters.
- Understand the concept of
statistical significance, and apply
statistical tests to check for
significance.
- Describe and interpret
correlations and linear regressions.
- Calculate and apply
non-parametric statistics.
- Understand how statistics can be
misused and misinterpreted.
Assignments
- You will be given suggested
assignments most days in class.
While these will not be turned
in for a grade, it is suggested
that you do the problems.
- At the very least, you
should look through them and
make sure you know how to do
each type of problem. We will go
through many of the assigned
problems in class.
- In addition to book
assignments, you will be given
review worksheets, the answers
to which will be posted online.
Quizzes
- There will be brief quizzes given each week after the first. These may
be given at any time during class.
- Quizzes may NOT be made up in terms of absences.
- Quizzes as a whole will count
for 15% of your grade.
Tests
- You will be given four
tests over the course of the
summer.
- Before each test you we
will review in class, and
there will also be a review
worksheet with questions
similar to the test that you
can check the answers to
online.
- By the nature of the
course, each test will to
some extent be cumulative,
reviewing what came before.
However there will be
nothing officially
cumulative in the final.
- Tests will be graded on
a straight points basis,
with all tests (including
the final) worth
approximately the same
number of points. (Each test
will be worth about 15% of
your grade.)
- Tests should be taken
when scheduled. If you will
be gone for a test, you must
schedule the make-up in
advance. Otherwise, you
can’t make it up.
Project
- All students will
complete an individual
or small-group project,
where you will apply
statistics to a
real-world situation.
- You will complete an
initial prospectus for
the project, a mid-term
progress report, a
written summary, and a
final presentation to
the class.
- You will receive a
letter grade on the
project, which will be
worth approximately the
same as one test
(approximately 15% of
your gradE).
Attendance
- It is assumed
that you will be at
each class session,
and you will find it
much easier to do
well if you attend
regularly.
Attendance will
count for 10% of
your overall grade.
You may miss 2
sessions and still
get an "A" on the
attendance portion
of your grade. For
each session you
miss, your
attendance grade
will go down one
letter (so if you
miss more than 5,
you will get an "F"
for attendance).
There are no
exceptions to the
attendance grade
policy.
Grades
- The standard
ILCC grading
scale applies:
- A = 90%+
- B = 80%+
- C = 70%+
- D = 60%+
- F = 59%-
- Pluses
and minuses
are not
recorded on
ILCC grades.
There is
generally no
"extra
credit" in
this class.
Weather
Cancellation
- In
case of
severe
weather,
the
college
will
announce
any
cancellations
on area
radio
stations.

Notes & Handouts
Below are links to notes and handouts given in this class. These are documents in Microsoft Word and in Adobe Acrobat format. You may wish to download these by right clicking and choosing "save target as". You may then read them on a computer that has MS Office and/or Acrobat installed.
These notes are the BASIS of the notes that will be presented in class. They may not include everything that is presented. Most of these notes are based on class presentations from earlier semesters, and the actual presentations vary somewhat from semester to semester. You are advised to use these notes as a guide and a starting point--NOT in place of taking notes in class.
There may occasionally be some errors in the notes. Also, a few graphical features of Word (such as equations and mathematical symbols) may cause difficulty in printing. In some cases the notes also use unusual fonts as a method of illustrating mathematics. You may notice this in certain symbols which appear as just blank spaces, squares, or unusual characters when you attempt to print these Word documents on some computers.
Notes
These may be substantially revised throughout Spring, 2017. It is
suggested you wait to download them until it is time for each chapter.
Also
note
that
some
graphics
and
special
characters
may not
print
correctly
in these
versions
of the
notes.
