### Full course description

Document your Data science knowledge with the W3Schools Data science fundamentals exam to get the W3Schools certification.

Knowledge of Data science gives us the tools to make better decisions.

Data is a collection of information. Gathering, structuring and processing that information allows us to analyse and understand how things are connected. With better understanding, we can make better decisions about any problem we want to solve.

The tools of Data science are programming, mathematics, and statistics.

Python is a programming language widely used by Data scientists. Python has freely available mathematical and statistical libraries, making it easier to perform data analysis.

Understanding the fundamentals of mathematical functions is important to make predictions and interpret the results of an analysis.

Statistics is the science of analyzing data.

All questions in the exam are based on the content of W3Schools' Data science tutorial. The tutorial gives fundamental knowledge of the Python programming, mathematics and statistics used in Data science.

The exam consists of 70 multiple choice or true/false questions. The exam is time-limited to 70 minutes.

Candidates must have 75% correct answers to pass the exam and become certified.

Immediately after completing the exam, you will be informed of your score and of your pass/fail status.
