Ask HN: How to practice data analytics skills? (derp.foo)

Merry Christmas YCombinatorions, I am looking to improve my data analytics skills, basically how to identify patterns, trends, useful insights from data. Can folks some suggest good web based tools for this please?

Not looking for books, but rather sample datasets I can use to visualize, analyze and test if I found the right insights.

There is a discussion on Hacker News, but feel free to comment here as well.

I've been taught that with any visualization, make sure it doesn't:

A. Don’t show much data. B. Show the data inaccurately. C. Obfuscate the data.

Even things that are obviously not done maliciously can mislead people, such as putting categories in a bar graph in alphabetical order rather than from most to least.

Although this is something that the industry doesn't really care if you know or not, it will help in correctly identifying patterns from visualizations
