Statistics is a branch of mathematics that is recommended to be a prerequisite for data science and machine learning. Statistics is a very broad field but we will focus in this section only on the most relevant part. -After completing this challenge, you may go to web development, data analysis, machine learning and data science path.

Data is any set of characters that is gathered and translated for some purpose, usually analysis. It can be any character, including text and numbers, pictures, sound, or video. If data is not put into context, it doesn't give any sense to a human or computer. To make sense from data we need to work on the data using different tools. +What is data?
