Note: if you have trouble downloading the file from github, go to the main page and select "Clone or Download" and then "Download Zip" as per the picture below. Tutorial 1:  Define the Problem and Set Up, Tutorial 2: Exploratory Data Analysis (EDA). Data analytics is used in the banking and e-commerce industries to detect fraudulent transactions. In this case the question was “how much (time)” and the answer was a numeric value (the fancy word for that: continuous target variable). Say you are going to the shop and you are able to choose between black, white, or red T-shirts.
