How doctors can end up overtreating when they lack knowledge of Bayes' theorem.
People give you anecdotal evidence to justify all sorts of non-sense. You want to tell them that anecdotal evidence is useless. But their stories are very strong and emotional. Hence, let's use same math to call out anecdotal evidence. Don't worry, we just use high school math for this.
These are not my main data projects, which can be found here: Link.
These are example projects that helped me learn Data Science concepts.
