Standard deviations and probabilities have become a great deal to grasp during the course. I could understand the concepts, but the formulas are a bit challenging to use. For instance, deviation relates to other statistical measures to calculate. As for probabilities, it is interesting through introductory parts, but when it comes to binomial probabilities, I was a bit stuck. I am preparing the final by taking some quizzes as a revision strategy and watching some tutorials from YouTube. Also, besides reviewing all the study materials, I am focusing more on these two topics.
