## Fall 2013

JOHN FELICE ROME CENTER, LOYOLA UNIVERSITY CHICAGO

COURSE CODE: "STAT 103"

COURSE NAME: "FUNDAMENTALS OF STATISTICS"

SEMESTER & YEAR: Fall Semester 2013

SYLLABUS

INSTRUCTOR: Gatto Renato, rgatto1@luc.edu

HOURS: Mon 19:00-21:30

UNITS: 3.00

PREREQUISITES:

OFFICE HOURS: Mon 18:00-19:00 by appointment

COURSE AIMS:

An introduction to statistical reasoning. Students learn how statistics has

helped to solve major problems in economics, education, genetics, medicine,

physics, political science, and psychology.

SUMMARY OF COURSE CONTENT:

Topics include: design of experiments, descriptive statistics, mean and standard

deviation, the normal distribution, correlation and regression, sampling,

estimation, and testing of hypothesis.

LEARNING OUTCOMES:

1. Represent and interpret quantitative information symbolically, graphically,

numerically, verbally, and in written form.

2. Recognize the limitations of mathematical and statistical models.

3. Develop an understanding of the nature of history of mathematics, its role

in scientific inquiry and technological progress, and its importance in dealing

with issues in the public realm.

4. Develop an understanding of the rudiments of statistics, including sampling and hypothesis testing, and the uses of statistical reasoning in everyday life.

-ASSESSMENT METHODS:

There will be 2 exams each carrying 20% of the final grade, a final examination (comprehensive) worth 40%, and homework worth 10%. The remaining 10% is associated with attendance and class participation:

2 Exams...................................................40%

Final Exam .............................................40%

Homework .............................................10%

Attendance and Class Participation .........10%

-ASSESSMENT CRITERIA:

The grade scale is as follows:

A: 90%-100% (The student demonstrates complete, accurate, and critical knowledge of all the topics, is able to make

appropriate connections among different parts of the subject matter, uses the appropriate language and terminology

correctly and rigorously and is autonomous in his study)

B: 80%-89% (The student has a somewhat accurate knowledge of the subject matter and uses clear logic in his/her

arguments)

C: 70%-79% (The student has the essential knowledge of the subject matter, understands the topics, and can express

it in a simple language)

D: 60%-69% (The student has a superficial, mnemonic knowledge of the subject matter, is uncertain and makes errors

in the presentations)

F: below 60% (At best, the students has a superficial knowledge of some of the topics discussed in the course. He

makes serious errors in the presentations).

Numerically, the final grade is computed as follows: G=0.20 E1 + 0.20 E2 + 0.4 F + 0.1 H + 0.1 A,

where G is the final grade, E1 the score in the first exam, E2 the score in the second exam, F the score in the final,

H the average score in the homework, and A is the score associated with attendance and class

participation. The conversion between numerical grade and letter grade is described by the following table:

A   100 - 93

A-  92 - 89

B+ 88 - 86

B   85 - 81

B-  80 - 78

C+ 77 - 75

C   74 - 71

C-  70 - 68

D+ 67 - 63

D   62 - 60

F   59 – 0

Cheating is not tolerated (please see the University Catalog for the policy regarding

Coming late to class or leaving early will be possible only with permission of the instructor.

No make-up exams will be given.

-ATTENDANCE REQUIREMENTS:

Attendance will contribute to the final grade. Full credit for attendance will be given to people

with two or fewer unexcused absences. Three or more absences will result with a proportional
