Basic Content

Basic concepts of statistics for business students are considered including descriptive statistics, probability concepts, random variables, probability distributions, expected values, point and interval estimation techniques, some hypothesis testing, and linear regression. Applications to a variety of business problems are stressed and computer statistical packages, concentration on Excel, are used.

 

LEARNING OUTCOMES: At the completion of the course, the student should be able to: 

1.

Demonstrate basic knowledge of statistics. Basic concepts in STAT 3309 include: probability distributions, hypothesis tests, confidence intervals, and linear regression.

2.

Demonstrate basic knowledge of computational procedures, the use of statistical packages, and interpret computer output from Excel and/or SPSS.

3.

Demonstrate analytic, critical reasoning, and problem solving skills.

4.

Communicate statistical knowledge orally and in writing.

Topic

Time

 

UNIT I – DESCRIPTIVE  STATISTICS

1.1-1.2

Overview of statistics and its uses in business as well as for classification of data.

0.5 hours

1.3-1.4

Discuss standard numerical measures of central tendency (mean, median) and measures of variability (range, interquartile range, standard deviation, variance) for non-grouped data. Stress is given to interpretation of these measures as well as to their calculation.

2.5 hours

1.5-1.11

Use graphical methods for displaying data, such as histograms, pie charts, bar charts, frequency polygons, ogives, and box plots. Stress is given to interpretation of these measures as well as to their calculation.

3 hours

Chapter 1

Investigate exploratory data analysis including graphical techniques and using computers. Computer assignments will be given.

1.5 hours

UNIT II – PROBABILITY AND SAMPLING DISTRIBUTIONS

Chapter 2;

3.1-3.5

Review basic probability. Extend probability concepts through the introduction of discrete random variables, probability distributions and their graphs, expected value and variance. Discuss binomial distributions, their calculations, properties, and the use of appropriate tables.

3 hours

3.10, 3.13-3.14, 4.1-4.9

Detailed discussion of the normal distribution, the standard normal (Z) distribution, and the use of appropriate tables.

7.5 hours

5.1-5.7

Discuss sampling, point and interval estimation techniques, and continuous sampling distributions with emphasis on normal distributions and the Central Limit Theorem and applications to probability.

1.5 hours

UNIT III –INTRODUCTION TO STATISTICAL INFERENCE

6.1-6.4, 6.6-6.9

Discuss confidence intervals for a population mean, the t distribution and its conditions (with appropriate tables), and calculate sample size for given confidence intervals.

3 hours

7.1-7.7

Discuss, in detail, hypothesis testing of population means for both large and small samples using p values, a levels, and critical values. Discuss conditions, stress the steps in hypothesis testing, and the use of critical Z (or t) values in decision making. A computer assignment must be given.

6 hours

UNIT IV – REGRESSION

10.1 -  13.12

Discuss bivariate data, correlation, and the simple linear regression model used in prediction. Hypothesis tests and confidence intervals will be included for the slope. A computer assignment will be given.

7.5 hours

 

 

 

 

General University Policies and Procedures

            All students are subject to the University of Houston-Downtown's Academic Honesty Policy and to all other university-wide policies and procedures as they are set forth in the University of Houston-Downtown University Catalog and Student Handbook.

            Reasonable accommodations will be made for students with disabilities covered by the Americans With Disabilities Act. Register through the Office of Disability Services in S409 (713-226-5227) and arrange for accommodations with me in a timely manner.

 

Class Policies

            YOU are expected to come to every class, be on time, take notes, read the textbook, ask questions, participate in a positive manner in class, complete the homework corresponding to the material discussed in class, correct your own homework by comparing with the answers provided in the back of your textbook. All work passed in for credit must have your name, book's page and section number, and all relevant work. See me concerning any additional questions.

            NO make ups will be given. If you miss a quiz, do "additional points" work that I assign to make up points. If you miss a test, see me as soon as possible (I will do your current average, discuss your options, and you will be given a required test to do for Homework points.).

            There will be no classes           September 1st, Nov 26-30th

            Last day to withdraw is          R, October 30th

            Our last day of class is            W, Dec 3rd (Bluebooks due.)

            Grades will be available from T, Dec 23rd (noon) at www.uhd.edu/eservices
