Easy to reach online datasets
There are plenty of websites that provide smaller or larger datasets that can be used for free or for a certain amount of money to practice DataScience related duties such as accessing data, recognition / understanding data content and data types, data cleaning / conversion / data manipulation (ETL) and finally representation of extracted key information, drawing consequences or making predictions, clustering, segmentation, and so on, depending on the predefined requirements or the possible ways of use of datasets.
It is rarely mentioned but double-checking the extracted information is an inevitable step not to mislead yourself or the stakeholders in a real-life project.
Here you find some websites helping to find datasets:
Here is a short list of such websites that give partially or completely free access to datasets:
- Datacamp - this website offers notebook-based data juggling, tutorials, and education in AI & ML domains
- Kaggle - this website offers competitions, but also tutorials and education in AI & ML domains
- Data.gov - USA Federal Government datasets, of course, the non-confidential part
- Earth data - collected by NASA
- Global Health Observatory Data - for those who like health-related issues or facts
Have fun with the data suiting you the best!
