These materials were created for “The Basics of DNA Evidence” workshop taught by the Forensic University in Spring 2022.
By the end of the course, you will be able to
|Topic||Key take-away points||Lecture notes|
|1. What is probability?||i) When it comes to probabilities, we do not trust our gut, we trust the formulas; ii) We estimate population probabilities from observed frequencies in samples; iii) The chosen sample is very important||notes|
|2. How do we combine probabilities?||i) Product rule: we can calculate the probability of simultaneous events when they are independent; ii) Addition rule: we can calculate the probability of different disjoint events||notes|
|3. How do we update probabilities when new information is available?||i) The conditional probability allows us to update a probability with new information; ii) Very important not to confuse the conditioning event as probabilities would change||notes|
You can find the 90-minute lecture including all three topics in this link.
