MATH 241


Integrated statistical methodology for the improvement of products and processes in terms of performance, quality and cost. Designed experimentation. Statistical process control. Software application. Laboratory activities.


This course covers the fundamental aspects of probability and statistics. The overall objective is for students to gain an appreciation of the inherent uncertainty and errors in all engineering and scientific data, and to provide the basic tools from probability and statistics to quantify these uncertainties.


  • Week 1:  Course info; use of statistics in engineering; sample mean and variance.
  • Week 2:  Event, sample space, probability, trees; counting rules, permutations, combinations, Venn diagrams; addition and multiplication rules; conditional probability; Bayes's rule.
  • Week 3:  Random variables, distributions, expected value and variance; functions of random variables; error-propagation; numerical experimentation.
  • Week 4:  Functions of many random variables; design-under-uncertainty; normal, binomial, hypergeometric distributions.
  • Week 5:  Poisson and exponential distributions, sampling, estimators, the Central-Limit theorem.
  • Week 6:  Review and problem solving.
  • Week 7:  Confidence intervals; estimation using numerical simulation.
  • Week 8:  Confidence intervals (standard error, T-dist, difference of means, paired observations, proportion, variance).
  • Week 9:  Concept of hypothesis testing, P-value (single mean, proportion, type I and II errors), hypothesis testing (variance, two means, pairs).
  • Week 10:  Hypothesis testing (goodness-of-t, independence, goodness-of-t).
  • Week 11:  Review and problem solving.
  • Week 12:  Analysis-of-variance (ANOVA).
  • Week 13:  Linear Regression, Multiple Linear Regression.
  • Week 14:  Design-of-experiments (DOE).
  • Week 15: Review and problem solving.
