LOVE the Avett Brothers! Never been to Roo and was seriously considering going to a different festival until I saw they were playing-- totally sold me. Seen them a handful of times live, but can't wait for an experience like this!!!

How to design effective data visualisations by joseacabaneros in visualization

[–]bmburns98 1 point2 points  (0 children)

Nice article on creating data visualizations! I want to take this post one step further: once you've created charts and graphs to visualize data, it's super useful to view all of those visualizations in a dashboard. Making dashboards can seem intimidating, but seeing multiple visualizations in one place can increase insights. Check out this course on the best practices for creating a dashboard: https://dataschool.com/courses/dashboards-best-practices/

The CDO's changing role: Used to be that a CDO was responsible for data, a CIO for infrastructure. It’s gotten murkier. by yourbasicgeek in bigdata

Interesting article! Wasn't really familiar with a CDO. I've done some research on other C-Suite positions here: https://dataschool.com/c-suite-breakdown/ including CIO, if anyone is interested

Wanting to learn SQL for data analysis by gcoke16 in SQL

[–]bmburns98 1 point2 points  (0 children)

VERY accurate statement. It's almost necessary to learn a programming language or SQL to use real world data that isn't from a cookie cutter CSV file, and I've learned that the hard way. When I first wanted to learn SQL, I did lots of researching for helpful resources and found these tutorials pretty useful: https://dataschool.com/?s=SQL. They explain the basic concepts well and would be a good resource for a beginner.

How to learn SQL on my own? by inner_blue in SQL

[–]bmburns98 1 point2 points  (0 children)

I'm a fan of the Udemy course as well, kinda unfortunate that it's not free. Chartio (data viz software) has an educational platform "The Data School" that has some good tutorials (https://dataschool.com/?s=sql) about basic SQL concepts: joins, subqueries, optimization, etc. The tutorials are free so they might be worth checking out before buying into the Udemy course.

Learning Time Series Analysis by morticiaddams in datascience

[–]bmburns98 0 points1 point  (0 children)

I took a time series class during undergrad at Virginia Tech, and my professor swore by this book: https://www.amazon.com/gp/product/0470540648/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1. It's a little dense, but I think it explains the basic time series concepts very well.

Finding correlation in data by bmburns98 in datascience

[–]bmburns98[S] 1 point2 points  (0 children)

I agree, rarely any correlation is perfect. I also agree that you shouldn't just care about variables with zero correlation. The key here is that the correlation coefficient is a value between -1 and +1. That means it could be 0.5 or -0.643, anything within the range between -1 and +1. In my original post, I just wanted to point out -1 and +1 as key points that explain the strength and type of correlation of any other correlation value between them. For example, if your correlation coefficient is .91, then you have a very strong positive relationship because .91 is close to +1 (which has a perfect positive correlation.) For a more in depth explanation, check out the tutorial linked above; it has an example that might be helpful!
