# Stat 2330 — Elementary Statistics and Probability — Virgil U. Pierce

### Required Textbook

Johnson and Kuby, *Elementary Statistics*, 11th ed. Cengage Learning. There is a custom UTPA edition which may be cheaper.

### Calculator

A scientific calculator is required.

### Course Pre-requisites

MATH 1334 with a grade of C or better, ACT math score of 20 or better, or THEA math score of 260 or better, or ACCUPLACER College Level Mathematics part score 70 or better.

### Course Description

This course is intended to provide the student with an elementary overview of the nature and uses of descriptive and inferential statistics. Topics include the definitions and fundamental theorems concerning measures of central tendency and dispersion, empirical and theoretical concepts of probability, the central limit theorem, tests of hypotheses, interval estimation, chi-square tests and regression and correlation.

### Student Learning Outcomes

After completing this course students will:

- Have the basic ideas regarding what is the difference between a population and a sample, and will be able to identify which is a representative sample and which is not.

- Understand the difference between Statistics and Probability.

- Represent given data through tables or pictures.

- Have the basic ideas of central tendencies and dispersions and be able to use calculators to calculate them.

- Get some heuristic ideas while looking at univariate and bivariate data and be able to draw conclusions on the required parameters.

- Calculate probabilities for binomial and normal probability distributions and use binomial and normal probability tables.

- Calculate confidence intervals and do testing of hypotheses using Normal table and t table for p-values and critical values.

### Attendance

Students are expected to attend each class. Missed classes will have a direct impact on your grade with certainty. Trust me. I have 13 years of teaching experience and I observe every year that students who miss class for whatever reason are at an extreme disadvantage.

More than 5 absences, regardless of excuse, may be grounds for an instructor initiated drop. Arriving late to class will count as an absence. Participation includes presenting solutions to the homework exercises to the class when asked.

### Homework

I cannot emphasize this enough: **HOMEWORK IS KEY TO MASTERING THE MATERIAL COVERED IN THIS CLASS**. Trying to do this course without doing all of the homework is analogous to learning how to swim without ever getting in the water. Trying to do this course without doing **MORE** than the assigned homework is analogous to learning how to swim by walking in water. You may think I am joking. I AM NOT.

Homework will be delivered through webwork. Furthermore homework will form the basis for class discussions where you will be expected to show (partial) solutions to problems to the rest of us — or to at least intelligently articulate where you are stuck.

### In-Class Activities

In class activities will include: Quizzes, presentations of problems to the class, and in class discussions.

### Class Wiki

There is a class wiki that will be used to deliver course material. You can reach it at [http://wikivirgil.wikidot.com]. You will need to register with the site to edit pages, please use your utpa login or your real name. Contributions you make to the wiki will count towards your class participation grade, you should sign your contributions. Examples of contributions you might make could be: A question posed, a question answered, a golasry entry, or an example.

### Tests

The tests will be given at the following times:

Test 1 | September 30 | in class |

Test 2 | November 4 | in class |

Test III | December 5 | in class |

Final Exam | to be announced |

### Grades

Your grade has 6 basic components: webwork homework, class participation (including — quizzes, presentation of homework problems, and contributions to the wiki), 3 in class tests, and the final exam. The first 3 components are of equal weight with each other, while the final exam is worth two of the others.

## Policies

- University Drop Deadline is {\bf November 14 }.

- Makeup Exams will only be given for documented illnesses and emergencies. It is imperative that you contact me
**by email**, except in rare cases, before the exam begins.

- Be aware: The state of Texas imposes penalties to students who drop to many classes (loss of financial aid, and a limit of 6 drops in Texas higher education). Please keep these in mind, and apply yourself to the course accordingly; if you are in a position to consider dropping the class check with your advisor and the University about the consequences first.

- It is assumed that you have read the Student Handbook, in particular the section on plagiarism and cheating. You are permitted to work together to solve the homework problems but all work handed in {\bf must} be written by you. No cooperation of any sort is permitted on exams.

- Students with disabilities are encouraged to contact the Disability Services office for a confidential discussion of their individual needs for academic accommodation. It is the policy of the University of Texas-Pan American to provide flexible and individualized accommodation to students with documented disabilities that may affect their ability to fully participate in course activities or to meet course requirements. To receive accommodation services, students must be registered with the Disability Services office (DS), University Center #322, 665-7005, ude.aptu|secivresytilibasid#ude.aptu|secivresytilibasid. The Director of Disabilities is: Christine Stuart-Carruthers, DS-Director, Ph: 665-5375, ude.aptu|srehturrac#ude.aptu|srehturrac.
