## コースについて

Exploration of Data Science requires certain background in probability and statistics. This course introduces you to the necessary sections of probability theory and statistics, guiding you from the very basics all way up to the level required for jump starting your ascent in Data Science. The core concept of the course is random variable — i.e. variable whose values are determined by random experiment. Random variables are used as a model for data generation processes we want to study. Properties of the data are deeply linked to the corresponding properties of random variables, such as expected value, variance and correlations. Dependencies between random variables are crucial factor that allows us to predict unknown quantities based on known values, which forms the basis of supervised machine learning. We begin with the notion of independent events and conditional probability, then introduce two main classes of random variables: discrete and continuous and study their properties. Finally, we learn different types of data and their connection with random variables. While introducing you to the theory, we'll pay special attention to practical aspects for working with probabilities, sampling, data analysis, and data visualization in Python. This course requires basic knowledge in Discrete mathematics (combinatorics) and calculus (derivatives, integrals)....

An introduction into statistics for the mathematical minded. This course brings up the mathematical basics of data analysis a bit more than other courses. That's why it might be interesting for you even when you are experienced in analytics but have been a bit sloppy on the mathematical background. Be aware that you need some knowledge of calculus for solving the quizzes.

The course is well taught. Even the teacher is not an English native, his ability to express the stuff in a clear and comprehensible way is excellent. I liked that they provide many quizzes so that you can test your understanding of the lectures immediately. Unfortunately no accompanying material is provided so you have to take you own notes while watching the lectures.

IT'S AN ALL STAR COURSE FOR ME , I WANT TO GET STARTED WITH DATA

AND TOOK THIS COURSE ON PROBABILITY AND STATISTICS AS THESE SUBJECTS SCARE

ME THE MOST BUT COURSE'S INSTRUCTOR GUIDANCE AND IN-DEPTH COURSE MATERIAL

HELPED ME OVERCOMING MY FEAR AND NOW I AM ON MY JOURNEY TO EXPLORE VARIOUS

REALMS OF DATA

THANKS SO MUCH FOR HELP

A good basic course: explicit and wide enough to cover everything you need to move on.
