DS201
The 60-minute DS201 examination evaluates knowledge administration in SQL, knowledge cleansing and preparation in Python or R, modeling abilities, mannequin analysis, unsupervised studying, and programming greatest practices together with model management and package deal constructing.
What to anticipate on the sensible examination
The sensible examination evaluates knowledge visualization and communication abilities by having you evaluate a enterprise downside, choose and create visualizations, and current a abstract of findings; it requires recording and submitting a presentation demonstrating the power to successfully visualize, body, convey, and summarize knowledge tales to various audiences together with enterprise leaders.
