After this course, you can run a data project in a structured way: sharpen the question, prepare the data, explore it and compare suitable models. You can then explain results so that business teams can make decisions from them, and you know what running a pipeline requires. The content follows the DSP-210 exam. The course suits you if you already analyse data or develop software and have a basic command of Python or R.
What you’ll take away.
- Turn a business question into a testable data science question
- Extract and clean data and transform it for analysis
- Explore data sets and put patterns into statistical context
- Build and test models and assess their limits
- Explain results clearly and outline the route to production

Frequently asked questions
Which exam is current?
DSP-210 is current, and the course is aligned with it. The earlier DSP-110 exam has been retired. Before you book the exam, it is best to check the current exam blueprint from CertNexus.
How much programming is involved?
The exercises involve working with code, so you should already be able to read and adapt simple scripts in Python or R.
Does CertNexus CDSP (DSP-210): Data Projects from Question to Result include a certificate?
This course prepares you for the CertNexus Certified Data Science Practitioner (DSP-210) exam. The exam and its fees are included only if your offer confirms this. The certificate comes from CertNexus. This is not an official vendor course unless the offer says so.
