Screening tests are tools that aid in the early detection of a particular disease. Frequently used in public health, they include Pap smears and mammograms, to name a couple. Screening tests have a set of qualities that can be understood and assessed mathematically, and epidemiological principles can be utilized to determine which are more helpful for detecting a particular illness.
In this course, the student will be introduced to the most important concepts of screening tests, including sensitivity and specificity, false positives and negatives, positive and negative predictive values, and likelihood ratios. Throughout the course, a contingency table will be used to explain each concept.
For optimal understanding, the student is required to be familiar with the basics of arithmetic, algebra, and epidemiology. Since some concepts may be very abstract to some, it’s encouraged to rewatch some video lectures until the concepts are fully grasped.
The lecturer is great! My concepts seem to be a lot clearer. However, the answers to the quiz questions need to be displayed somewhere, as i found them quite tough.
This is just another awesome series.....Great job Dr. Raywat....You just have a way of making it so simple while keeping it truly interesting....Kudos Lecturio...
This series is good to watch before doing the same section from the Kaplan videos. Don't bank on getting detailed explanations but rather concise i.e. what you need to know!
