IT 223 Data Analysis
Summary
Introduction to univariate data analysis methods. Descriptive statistics and data visualization methods. Overview of sampling techniques for data collection, and introduction to statistical inference methods for decision making including simple linear regression, estimation procedures using confidence intervals and hypothesis testing.
Texts
OpenStax Statistics: The IT program committee has moved to an online textbook that does not have a required payment. The publishers of the text do request a contribution, which I would encourage all of you to make, but it is not required. The textbook can be found at: https://openstax.org/details/books/introductory-statistics
OpenIntro Statistics: An excellent book. Perhaps has better explanations the OpenStax. https://www.openintro.org/book/os/
Humongous Book of Statistics Problems: You can find this book at Amazon.com. It is very inexpensive. While this cannot be used as the course textbook, it would be a very helpful tool for you in this course. In spite of its title, the book is not huge or daunting. It is a book of straight-forward exercises with explanations. Doing lots of problems is the key to getting through the course, so I would strongly encourage you to buy and use this book.
Prerequisites
Only basic algebra is required.
Math and Computing Domain: Statistical Reasoning (MC-SR) LO
This section applies ONLY to those undergraduate students who wish to receive MC-SR credit. All other students may disregard.
Students who successfully complete IT 223, will have fulfilled the Liberal Studies Program – Math and Computing Domain – Statistical Reasoning category requirement.
List of MC-SR Learning Outcomes
Statistics is a rigorous intellectual challenge that must be approached systematically with extreme attention to detail. The assumptions, and mathematical rigor used to make decisions regarding which formulas to apply, as well as to build and evaluate models, require a solid understanding of the underlying theory. To that end, students will be asked not merely to “get the answer”, but to always justify their answer(s). Students will be confronted with scenarios in which the “expected” formula or model turns out to be the “wrong tool for the job”, and it is expected that they will be able to recognize such situations when they occur. In other words, the student will, at all times, be expected to understand the underlying theory and assumptions that underlie a given approach.
- Recognize and explain statistically based results from real data (either primary or secondary) and evaluate whether reported conclusions reasonably follow from the study and analysis conducted.?
- Use statistical software to produce and interpret graphical displays and statistical summaries.?
- Recognize and explain the roles of variability and randomness in interpreting data and drawing conclusions.
- Explain common ethical issues associated with sound statistical practice, including those associated with research design, and their impact on statistical decision-making.
- Measure the strength of association between variables and identify possible effects of confounding or interacting variables on the interpretation of the association.
- Apply basic ideas of statistical inference, including confidence intervals or hypothesis testing, in a variety of settings.
Math and Computing Domain Writing Expectations
Writing is integral for communicating ideas and progress in science, mathematics and technology.
The form of writing in these disciplines is different from most other fields and includes, forexample, mathematical equations, computer code, figures and graphs, lab reports and journals.
1. Students will demonstrate skills in writing at an appropriate level of detail (including the ability to summarize effectively), choosing an effective format, paraphrasing and citation of sources as required, technical accuracy, and quality of expression, including grammar, spelling and word usage.
2. Students will be required to write the equivalent of a minimum of five to ten pages,
distributed across a series of assignments. Specific types of writing required will be a part of the description of assignments appropriate to the topics covered.
This syllabus is subject to change as necessary during the quarter. If a change occurs, it will be thoroughly addressed during class, posted under Announcements in D2L and sent via email.
Evaluations are a way for students to provide valuable feedback regarding their instructor and the course. Detailed feedback will enable the instructor to continuously tailor teaching methods and course
content to meet the learning goals of the course and the academic needs of the students. They are a requirement of the course and are key to continue to provide you with the highest quality of teaching. The
evaluations are anonymous; the instructor and administration do not track who entered what responses. A program is used to check if the student completed the evaluations, but the evaluation is completely
separate from the student’s identity. Since 100% participation is our goal, students are sent periodic reminders over three weeks. Students do not receive reminders once they complete the evaluation.
Students complete the evaluation online in CampusConnect.
This course will be subject to the university's academic integrity policy. More information can be found at http://academicintegrity.depaul.edu/ If you
have any questions be sure to consult with your professor.
All students are expected to abide by the University's Academic Integrity Policy which prohibits cheating and other misconduct in student coursework. Publicly sharing or posting online any prior or current materials from this course (including exam questions or answers), is considered to be providing unauthorized assistance prohibited by the policy. Both students who share/post and students who access or use such materials are considered to be cheating under the Policy and will be subject to sanctions for violations of Academic Integrity.
All students are required to manage their class schedules each term in accordance with the deadlines for enrolling and withdrawing as indicated in the University Academic Calendar. Information on enrollment, withdrawal, grading and incompletes can be found at http://www.cdm.depaul.edu/Current%20Students/Pages/PoliciesandProcedures.aspx.
Students who feel they may need an accommodation based on the impact of a disability should contact the instructor privately to discuss their specific needs. All discussions will remain confidential.
To ensure that you receive the most appropriate accommodation based on your needs, contact the instructor as early as possible in the quarter (preferably within the first week of class), and make sure that
you have contacted the Center for Students with Disabilities (CSD) at:
Lewis Center 1420, 25 East Jackson Blvd.
