University Studies Course Approval Proposal

 

Flagged Courses Mathematics and Statistics

The Department of Mathematics and Statistics proposes the following course for inclusion in University Studies, Flagged Courses, Mathematics and Statistics at Winona State University. This was approved by the full department on Thursday, February 1, 2001.

Course: Data Management using SAS (STAT 255), 3 s.h.

Catalog Description: An introduction to the statistical package SAS. The course will focus on DATA step programming, and selected basic PROC routines, with an introduction to SAS/GRAPH if time permits.

This is an existing course, previously approved by A2C2.

General Discussion of Flagged Courses – Mathematics and Statistics in relation to STAT 255

Mathematics/Statistics Flag

The purpose of the Mathematics/Statistics Flag course requirement is to reinforce the outcomes specified for the basic skills area of mathematics/statistics. These courses are intended to provide students with significant practice in applying prerequisite mathematical or statistical knowledge.

Courses can merit the Mathematics/Statistics Flag if students will be required to make essential use throughout the semester of mathematical or statistical models appropriate to their prerequisite knowledge of those areas, and if the correct use of techniques based on such models will comprise a significant portion of a student’s final grade. It is understood that mere rote computations, algebraic manipulations, or graphical design without inferential content would not merit a Mathematics/Statistics Flag.

These courses must include requirements and learning activities that promote students' abilities to...

a. practice the correct application of mathematical or statistical models that are appropriate to their prerequisite knowledge of those areas

The purpose of this course is to introduce students to an extremely popular statistical package among statisticians in business, industry, and academia. The assignments in the course require students to use their knowledge of introductory statistics to produce programs in SAS that produce the correct results.

b. make proper use of modern mathematical or statistical methods appropriate to their level of prerequisite knowledge, to include, if statistics is used in a substantive way, the use of a statistical package with graphics capability when appropriate.

The focus of this course is learning how to use the statistical package, SAS, to produce correct results. Part of the course is focused on learning how to use some of graphical capabilities of SAS. Hence, this course uses a statistical package with graphics capability in a substantive way.

Course Syllabus/Outline

Course title: Data Management using SAS

Catalog description: An introduction to the statistical package SAS. The course will focus on DATA step programming, and selected basic PROC routines, with an introduction to SAS/GRAPH if time permits. This is a University Studies course satisfying requirements for the Mathematics and Statistics Flag.

Statement of the major focus and objectives of the course: The purpose of the course is to give students a solid introduction to SAS DATA step programming. One objective is to help students secure good jobs, either as interns during college, or as new graduates with a bachelor's degree. The other objective is to give students going on to graduate school a useful skill, since many research assistants do much of the same work as people with bachelor's degrees who work in industry do. Moreover, any student who goes on to secure a master's or PhD in statistics will want to be able to make effective use of SAS's many capabilities.
