Centre for Applied Statistics Courses

Understanding and assessing reliability and validity are important when developing and using new tests and measurement tools. This course gives an introduction to the concepts of reliability and validity, how the two are associated, and the methods commonly used for assessing these factors in different data types and study designs. Knowledge of basic statistical concepts (e.g., p-values, confidence intervals) is beneficial for this course. The following topics will be covered during this one-day course:

  • Types of validity
  • Assessing validity of numeric and categorical outcomes
  • Types of reliability
  • Assessing reliability for numeric outcomes
  • Bland-Altman Limits of Agreement
  • Intraclass Correlation
  • Assessing reliability for categorical outcomes
  • Kappa
  • Internal reliability of assessment measures
  • Correlation

Computers are not required for this course.

"Excellent course - reinforced self-learning. I liked the fact it wasn't software dependent - e.g. not 'Reliability using R' - but they still provided code for the major statistical packages. It was obvious that the lecturer had excellent knowledge on the subject. It was the first time that I had attended one of the CASC courses, and I wouldn't hesitate to attend one again."

"I really enjoyed the course as it was very well taught and presented"

"Really good presenter, clear slides and well-paced day. The content was very useful, but I had specific questions about this topic before I came and the presenter found time to answer them, which I really appreciated"

"Very useful course, presented clearly and coherently"

"I thought the presentation style was great and the content pitched appropriately."
