Catalog Description

 

Statistics I course aims to cover all major aspects of the descriptive statistical and probability theory and their applications by using SPSS. There are many examples and problems concerning diverse application areas that will show the pertinence of statistical methodology to solving real-world problems. Descriptive statistics deals with methods of organizing, summarizing and presenting data in a convenient and informative way by using graphical or numerical techniques. The course provides a modern approach that emphasizes applications and how statistics is used in every business economics, economics or social sciences function. It aims in giving the students the foundations for continuing with inferential statistics. The course also gives the foundations of discrete probability theory.

 

Prerequisite:  College Algebra or Visualizing Mathematics

 

Course Purpose:

 

The main purpose of Statistics I course is the collection, analysis, interpretation, and presentation of qualitative or numerical data for assisting in making more effective decisions. Every person in today’s society needs to have a basic understanding of data analysis and statistical concepts, in order to be able to think critically about the quantitative information we encounter every day, from opinion polls to headline news reports based on scientific studies. We need to be able to understand the information that is being presented and to ask the right questions about any conclusions that are drawn from it.

One of the main aims is to prepare undergraduate students in the theory of descriptive statistics with emphasis in interdisciplinary applications, in order to continue with inferential statistics. The usefulness of each statistical method introduced is illustrated by several relevant examples.

Required Readings:

Main textbooks:

  • Lind, Marchal, and Wathen, Basic Statistics for Business & Economics, eighth edition, McGraw-Hill, 2013.
  • Field A. P., Discovering Statistics Using SPSS, second edition, Sage Publications, 2005.

Additional textbooks:

  • Attwood, G. Dyer, and G. Skipworth, Statistics 1, Heinemann Modular Mathematics, 2000.
  • Attwood, G. Dyer, and G. Skipworth, Statistics 2, Heinemann Modular Mathematics, 2000.

 

Course Objectives

Upon completion of this course, students should be able to:

  1. Explain and apply principles of study design and data collection.

Identify the relevant population, sample, study units (subjects), variables, and factors.

  1. Produce and interpret graphical summaries of data such as  histograms, stem-and-leaf diagrams, and frequency and cumulative frequency distributions
  2. Recognize qualitative versus quantitative data and the relevant data displays for each;
  3. Produce and interpret numerical summary statistics, such as mean, median, mode, range, standard deviation, variance, and percentiles.
  4. Distinguish between observational studies and controlled experiments;
  5. Get the fundamentals of discrete probability theory and counting techniques, rules of addition and multiplication, two-way tables of counting data and tree diagrams.
  6. Understand properties of binomial and uniform distributions; identify situations that follow a binomial distribution, use the tables.
  7. Understand properties of the normal curve and standard normal curve, identify data that follow a normal curve, find chances and percentages using a normal curve, use the tables.

The laboratory part of the course will provide students with hands-on experience with the SPSS. Students will be able to generate tabulated reports, charts and plots of distributions and trends, descriptive statistics and conduct some statistical analysis.

Course Requirements

Participation: Participation extends beyond mere attendance. Active participation is meant as the effort and the interest that a student shows in the class, including homework. After each session students are expected to study all the relevant material, read all the associated exercises, identify the difficult points and pose their questions in the next session either directly to me or in the class. You may miss up to three classes without penalty – your first two absences count whether you have a good excuse or not. The only exceptions to this rule are severe illness (doctor’s note required) and UNYT approved trips/activities. Appropriate documentation for absences beyond the first three is necessary the class day directly before or after the one you miss. In general: this class is intensive and interactive. Missing class could seriously affect your grade! Students who are absent more than 20% of the total hours of the semester (i.e. 9 hours) may be required to withdraw from the course.

Class conduct: Exams are closed books. Also, you use your own calculator and nothing else will be allowed. Mobile phones are strictly not tolerated in the class for any use (including computations). Cheating and plagiarism in any form will result immediately in the grade F.

Students are reminded not to approach the instructor for copies of the previous week’s materials during, or immediately after class. Students are expected to collect materials from their classmates or see the instructor during the office hours.

Students are responsible for everything that is announced, presented or discussed in class. The way to avoid any misunderstanding associated with this course is to attend class. Please, be courteous during class; both to me and your colleagues. I find late arrivals distracting, which cause a decline in the quality of my lecture.

 

Exams: Two examinations will be taken, a midterm exam during week seven of the course and a final exam covering all course content during the final examination period. Exam format may combine a mixture of short answer, true/false, matching, sort answer, and reasoning problems covering all readings, lecture, hand-out and class discussion content. Another computer based test in SPSS will be included in the period between the midterm and final exam.

 

General Requirements

Deadlines in submitting the homework are critical. Therefore, late assignments and absence from tests will not be tolerated.   In the event of illness or emergency, contact your instructor IN ADVANCE to determine whether special arrangements are possible. The University’s rules on academic dishonesty (e.g. cheating, plagiarism, submitting false information) will be strictly enforced. Please familiarize yourself with the STUDENT HONOUR CODE, or ask your instructor for clarification.
