The SUMS talk for this week will be from Matthew Fitzpatrick, he has kindly provided the abstract below: Abstract: One of the greatest abuses of mathematics in scientific research (and life in general) is the abuse of probability and statistics. It is something that everyone needs to understand yet nobody can get their head around. The reason is that probabilities need to be defined for each context! Thus, there is a philosophical side to statistics, which leads to many heated debates, sometimes leading to people BECOMING statistics! I will talk about some instances where understanding probabilities can help you and if you’re good, there will be some youtube clips!
