Math 105 : Topics in Mathematics
Course Description and Organization
Online Summer 2018 Course (Class No. 84548)
Introduction
In this course the instructors select various topics in mathematics,
for a second course in mathematics. Purpose is to provide
the students with some experience and insight into several areas of
mathematics not normally covered in elementary courses.
This instructor designed this course to provide some insight into
application of statistics, preceded by a foundation in probability.
Such a design was possible, at this level,
due the availability of advanced calculators.
The course is dependent upon such a calculator, TI84 (Silver Edition).
Statistics has a wide range of applications in daily life, at a very basic intellectual level.
The goal would be that,
by the end of this course, statistics would become part of student's daily intellectual skills. In particular, one would be able to interpret survey and poll reports disseminated daily on TV and newspapers.
Meetings:
This is an online course.
There will be no face to face meetings.
Main mode of communications would be emails.
Content, Goals and objectives:
We use my online Lecture Notes for this course and no textbook.
There are nine lessons (or chapters) in this course. These lessons can be divided into three parts:
Part 1 (Descriptive Statistics):
Lesson 1 and 2 constitute the Descriptive Statistics part of this course. We discuss various representations
of data in pictorial and numerical manners.
In Lesson 1 we learn to compute frequency distributions.
In Lesson 2 we diacuss mean, median, quartiles,
standard deviation.
You will use TI84 (Silver Edition) to do the computation in these two
lessons. Follow the instructions given, in those boxes,
to use TI and work out the homework problems.
Part 2 (Probability and Mathematics): Lesson 3, 4, 5 and 6 would provide
the background in probability that is needed for statistics.
Probability would be used as
a measure chances of errors in statistical inferences.
A great part of probability computations would be done using TI84 (Silver Edition).
Part 3 (Inferential Statistics): Lesson 7, 8, 9 constitutes the final part of the course where we do statistical inferences, which is the main goal of this course. We discuss estimation and statistical
hypotheses testing.
Again, much of the computations would be done with the aid of TI84 (Silver Edition).
Homework
Homework has been posted in the Lecture Notes
site.
 You would email the answers to me every Monday. I am mainly interest in the final answer.
 Due Dates are also given in the
Lecture Notes
site.
Grading Scheme:

 You are allowed to bring a standard size paper with formulas and notes.
You will also need to bring your TI84 (Silver Edition).
Do not take the test without TI84.
 Important: I will not give you a grade unless you take the
supervised Final.
If you are out of town, you may work with CODL to arrange such exams.

Material
 A TI84 (Silver Edition) would be essential for this course. This version of TI84 has the invT function in the DISTRmenu.

No textbook is required for this course. The notes given in the lessons would suffice.
Important Dates:
Tuesday, June 5, first day of classes
Wednesday, June 13, last day to drop without a W
Tuesday, July 17, withdrawal deadline
Friday, July 27, last day of classes
