University Studies Course Approval Proposal
Unity and Diversity – Critical Analysis

The Department of Mathematics and Statistics proposes the following course for inclusion in University Studies, Unity and Diversity, Critical Analysis at Winona State University. This was approved by the full department on Thursday, January 4, 2001.

Course: Industrial Design of Experiments I (STAT 321) 3 s.h.

Catalog Description: An introduction to applications of statistical methods used by industrial researchers to aid in the solution of certain types of industrial problems. Methods to include hypothesis tests, analysis of variance, factorial designs, fractional factorial (screening) designs. There will be industrial case studies and actual (hands-on) experience at local industries (when available). STAT 321 is a University Studies Course satisfying requirements for Critical Analysis. Prerequisite: An introductory statistics course (preferably STAT 210. Offered spring semester.

This is an existing course, previously approved by A2C2.

Discussion of relevance of Critical Analysis objectives (a, b, c, d below) for STAT 321:

  1. evaluate the validity and reliability of information;
  2. This course concerns itself with designing the collection of data, and then analyzing it. There is an emphasis on obtaining valid, reliable data through repeated measures. Methods for recognize outliers, or invalid data, are included.

  3. analyze modes of thought, expressive works, arguments, explanations, or theories;

The nature of the course is methods for testing of hypotheses. Critiques of data analysis and conclusions reached by others is required through case studies.

c. recognize possible inadequacies or biases in the evidence given to support arguments or conclusions;

In testing data to support hypotheses, a step is taken to quantitatively assign the risk of reaching wrong decisions. Mathematical models for explaining the relationship of input to output variables are analyzed for lack of fit to collected data. This lack of fit includes inadequacies and biases.

d. advance and support claims.

The scientific method is fully utilized in this course:

bulletHypotheses are advanced, bulletData is collected and analyzed,

Conclusions are drawn based on statistical evidence.

STAT 321 is a University Studies Course satisfying requirements for Critical Analysis. Following is a list of the Critical Analysis objectives that will be covered in this course, with reference to "Topics Covered" below, by Roman numeral:

a. evaluate the validity and reliability of information by measuring variability in data (topics II, III, IV, V, VI, VII);

b. analyze modes of thought, expressive works, arguments, explanations, or theories by performing hypothesis tests by analysis of experimental data (topics II, III, VII);

c. recognize possible inadequacies or biases in the evidence given to support arguments or

conclusions by assigning risks to decision-making (topics II, III, IV);

d. advance and support claims by analysis of experimental data that may support or negate hypotheses (topics II, III, V, VI, VII, VIII).
