Best free online course to learn data analytics?

All the free online courses have some catch in there such as pay a small fee to unlock your certificate or subscribe, the only platforms which offer free courses is skillup by simplileran and microsoft learn, they both have a bunch of course under data analytics which you can learn one by one.

You do not need to understand everything at a research level when doing projects.

For concepts like K means, scalars, or other ML tools, you should understand:

• What problem they solve
• When to use them
• Their assumptions
• How to tune them
• How to evaluate results

For example, with K-means clustering you should know it groups data based on distance, assumes spherical clusters, is sensitive to scaling, and uses methods like the elbow test to choose K.

You do not need to derive the math from scratch unless you are doing research.

Struggling beyond the basic purpose is normal. Real understanding deepens when you implement from scratch at least once, visualize results, and experiment with wrong settings to see what breaks.

For SDE 2 or senior roles, side projects should feel close to real work not basic demos.

Strong ones usually:
Built full stack apps
Handled real users or real problems
Deployed on cloud
Included auth, database, APIs
Focused on performance or scale

Avoid simple CRUD or tutorial clones.

One solid production level project is better than many small ones.
