Business Systems Analyst | Master's in Business Analytics Candidate, William & Mary The data playground and monthly challenges are some of my favorite aspects of the Maven Analytics platform! EARLY BLACK FRIDAY ENDS SOON! SAVE UP TO 50% ON MAVEN PRO PLANS Synthetic data on ~1k patients of Massachussets General Hospital from 2011-2022, including information on patient demographics, insurance coverage, and medical encounters & procedures. How many patients have been admitted or readmitted over time?

How long are patients staying in the hospital, on average? How many procedures are covered by insurance? Here is a collection of data sets that I have made (clean and dirty), just for you! I hope this will make your data journey smoother than mine was to start off with! This is an operations dataset that I generated using Python and ChatGPT. There has been a lot of thought put into making this data set realistic yet random.

There are real (fake) trends that you can pull out of this data. The product names are a little rough around the edges.... feel free to make changes! You can access the data and Python script to generate it here I took my operations data set, and made it dirty. I have worked with almost 20 clients at this point, so I was trying to represent some of the common "dirty" things I see in the data.

I will not spoil it for you in case you want to explore the data yourself, but if you need some clues as to what "dirtying" I did, there is a file in the... I recommend trying out cleaning this data in SQL and Tableau, not manually in Excel, if you're looking for a challenge! This time I used someone else's data to make it dirty - the fan favorite Maven Analytics. You can find the original dataset here. Be sure to check out the maven pizza sales challenge in LinkedIn (just search it) if you need inspiration. Here is my GDrive folder with the files.

A good end-to-end project would be taking the dirty data I have created and using SQL (or Python/R!) to clean it, then bringing it into Tableau and visualizing it there. Or, you can do you data cleaning in Tableau! Up to you how you do it, but please tag me in a LinkedIn post if you do use it in your portfolio and find my dirty data helpful. I'd love to hear it!As a reminder (or maybe this is your first time hearing it), if you include a link in your post LinkedIn won't show it to as many people. My suggestion is to export an image of your project and attach that as a picture to a post where you talk about the project. Then just attach any links in the comments.

Be sure to only use a few relevant hashtags! Maven Analytics has a free data playground that I send everyone to. I did not find it until after I got my job, unfortunately. I was so stressed about finding free data that it held me back from doing projects. Maven not only has a great collection of free and beginner friendly data, but it's also got challenges attached to many of the datasets which include guided prompts to help you get thinking about... While you're there, be sure to check out their free portfolio hosting platform and amazing (paid) courses.

Below are the best resources I've found related to data analytics whether it's learning new skills, hosting a portfolio, or get inspiration from creators. I update this periodically as I find new resources. This is similar to my Github repo: data-analytics-resources, which is an open source project. Also some of these links are affiliate links meaning if you decide to purchase anything through the link, I may receive a small commission at no extra cost to you. This support helps me continue to provide content. Thank you for your support!

All links that are affiliate links will be clearly indicated with a *. The following resources include everything technical about learning data analytics. From course platforms and specific courses to where you can practice your coding skills or host your portfolio. Websites where you can find specific courses on tools like SQL or Python. Some platforms go into more detail about the soft skills and how to break into tech as well. Welcome to my collection of open datasets!

This repository is a result of my passion for learning data analysis and sharing the knowledge with others. The datasets here are created for practice and educational purposes. While they do not contain real data, they follow real-life patterns to provide a realistic foundation for your analysis projects. When I started learning data analysis, I found a significant scarcity of diverse datasets. Free datasets are not always easy to find, and this makes it challenging for apprentice data professionals to practice and improve their skills. I felt the need for a free, accessible source that provides various types of datasets, allowing learners to perform different kinds of analysis.

These datasets are modified to follow real-life patterns, and they are designed to be helpful for learning different techniques and using various tools for analysis. By sharing these datasets, I hope to make it easier for others to practice, experiment, and grow in their data analysis journey. Here is a description of the available datasets: Each dataset is designed to be a useful resource for practicing various data analysis techniques, from basic exploration to advanced machine learning applications. Which brand has had the most Super Bowl commercials? Do they have a distinct style?

How have different characteristics for commercials trended across time? Can you identify any patterns for the most successful commercials on YouTube? Which characteristics are paired most often? Can you find any unusual combinations?
