Statistics deals with collections of data organized in 1,2,3 or more dimensions. Matrix notation is the best way to compactly represent such data. This course provides the basics of vector and matrix algebra and operations necessary to understand multivariate statistical methods including the matrix inverse, generalized inverse and eigenvalues and eigenvectors.

Overview
Learning Outcomes
Students who complete this course will be introduced to vectors and matrices, matrix inverse and linear equations, Eigenvalues and Eigenvectors, and symmetric matrices. It is designed to be a refresher, or an introduction to matrix methods for anyone interested in multivariate statistics, modeling, designing experiments or data mining.
- Define scalars, vectors, matrices and arrays, and use proper notation
- Conduct vector and matrix operations
- Calculate order and rank for a matrix
- Find the eigenvalues and eigenvectors of a real, square matrix
- Solve a system of linear equations and the generalized inverse
Who Should Take This Course
Matrix algebra is used heavily in multivariate statistics, and the theory behind many statistical modeling procedures. Matrix notation is used even more widely. If you are interested in taking courses in multivariate statistics, modeling, design of experiments, data mining or other topics involving multivariate data and need a refresher in, or introduction to matrix methods, you should take this course.

Introductory Statistics
We assume you are versed in statistics or have the equivalent understanding of topics covered in our Statistics 1 and Statistics 2 courses. but do not require them as eligibility to enroll in this course. Please review the course description for each of our introductory statistics courses, estimate which best matches your level of understanding of the material covered in these courses, then take the short assessment test for that course. If you can not answer more than half of the questions correctly, we suggest you take our Statistics 1 and Statistics 2 courses prior to taking this course.
- For Statistics 1 – Probability and Study Design, take this assessment test.
- For Statistics 2 – Inference and Association, take this assessment test.
The additional preparation found in Introduction to Statistics 3 – Regression and ANOVA is also helpful.
What Our Students Say
The instructor, Dr. LaBudde was highly effective. His written lectures contributed greatly to my understanding and his patient and lengthy answers to my at times overly general questions were extremely informative. It would be hard or impossible to get this information on my own

Additional Course Information
Organization of Course
This course takes place online at The Institute for 4 weeks. During each course week, you participate at times of your own choosing – there are no set times when you must be online. Course participants will be given access to a private discussion board. In class discussions led by the instructor, you can post questions, seek clarification, and interact with your fellow students and the instructor.
At the beginning of each week, you receive the relevant material, in addition to answers to exercises from the previous session. During the week, you are expected to go over the course materials, work through exercises, and submit answers. Discussion among participants is encouraged. The instructor will provide answers and comments, and at the end of the week, you will receive individual feedback on your homework answers.
Time Requirements
This is a 4-week course requiring 10-15 hours per week of review and study, at times of your choosing.
Homework
Homework in this course consists of guided numerical problems to test the concepts.
In addition to assigned readings, this course also has the instructor’s expert write-ups on important concepts.
