If you’re new to datasets, Kaggle is a great site that will help you explore different datasets and get excited about all the possibilities in data science and analytics. The following websites also offer datasets that are free for public use. Review these sites so you can learn where to access datasets to practice data analysis, test your management system, or find statistics to assist with an upcoming project.

The BuzzFeed site is known for providing unbiased news and information on current events. The site also conducts numerous surveys and pulls data to formulate statistics that relate to these current events. You can visit the BuzzFeed archives section or use the site’s search function to pull stories that relate to the subject you need more data about.

You may also visit a reliable dataset resource site, such a GitHub, to find BuzzFeed datasets. When you locate the dataset you need, consider linking back to the article to find the data or download the dataset directly from the site.

BuzzFeed has covered numerous topics over the years so the free datasets available to you may vary. Some of the datasets you may find on the site include:

If you’re in the process of earning an online master’s degree in data science, datasets on the BuzzFeed site may be helpful in upcoming projects. You can also use this data to learn more about how recent events have impacted the world or to create your own infographics to help viewers understand the effects of these events.

Reddit is a public, user-generated content sharing site that allows users to post information and observations.
