Course Description

Statistical methods for analyzing and interpreting process data are discussed, with special emphasis on techniques for continuous improvement of process operations. Topics include: role of data in assessing process operation, identifying major problems, graphical and numerical summaries, principles of valid inference, probability distributions for discrete and continuous data, process capability, comparing process performance to target values, comparing performances of two processes, control charts, and an introduction to linear regression analysis.

Objectives and Outcomes

The objective of this course is to develop competencies in the use of statistical tools for the analyses of data typically encountered by chemical, geological and mining engineers and engineering chemistry students and graduates. These techniques can be used to analyze laboratory and field data, as well as operating data obtained from industrial processes.

Specific course learning outcomes include:

  1. Summarize, visualize and interpret data using tabular and graphical methods.
  2. Apply simple discrete probability models to analyze data related to quality such as particle size and ore concentration, and to evaluate risk factors such as safety and environmental compliance.
  3. Formulate confidence intervals and hypothesis tests for the sample average and sample variance under standard conditions.
  4. Apply continuous probability models to assist in decision making with applications to quality improvement, resource estimation, safety and environmental compliance.
  5. Apply computer intensive methods to extend applications of statistical methods to non-standard situations.
  6. Develop and analyze linear models to describe and predict process and laboratory behavior.

This course assesses the following attributes:

  • Knowledge Base for Engineering (CLO 1-6):
    CHEE-KB-MATH -3. Develops and applies statistical methods to study, analyze, and interpret data obtained from chemical processes.
  • Problem Analysis (CLO 1-6):
    CHEE-PA-1. Identifies known and unknown information, uncertainties and biases.
    Evaluates validity of results, risks, errors and uncertainties.
  • Engineering Tools (CLO 2, 6)
    CHEE-TOO-3. Uses appropriate statistical tools to analyze instrumentation, simulation,or process data and to assess appropriateness of results

Relevance to the Program

CHEE 209 is an introductory course in probability and statistics and develops skills that are essential to engineers of all disciplines. Students from Geological Engineering, Chemical Engineering, Engineering Chemistry and Mining Engineering take this course. Examples from these disciplines will be used to demonstrate the various techniques. The skills acquired in this course are further developed in a more advanced course, CHEE 418 “Strategies for Process Investigations”.
