What is Data Storytelling? 

Oftentimes data is presented in a manner that is dry or incomprehensible to a general audience. Data storytelling is a more interactive and compelling way to present information. Data storytelling is defined as using visualizations to tell a narrative that communicates insights about data to a wider audience.

When writing a data story, start by collecting your data. Look for the most interesting trends and determine the main points you want to get across in your data story. A data story should have a complete narrative rather than being a series of barely connected data visualizations. Make sure the story you are telling is appropriate for your audience.  

Resources for Creating a Data Story: 

The Scholarly Commons Collection is located in the UIUC Main Stacks. Books in this collection are available to check out. The collection includes books that provide introductory information to data storytelling. 

  1. Effective data storytelling : how to drive change with data, narrative and visuals 

This resource is available to UIUC faculty, staff, and students online. It focuses especially on the narrative aspects of data storytelling rather than the visualization aspect. This book explains the psychology of why storytelling is such an effective communication tool.  

  1. Storytelling with data : a data visualization guide for business professionals 

This resource is only available as a physical book. Data storytelling is a method often used by business professionals to impart information in a more meaningful and persuasive way. This book speaks specifically to business professionals and explains how to consider context, determine the appropriate format for the story, and speak to an audience in a compelling way.  

  1. Storytelling with data : let’s practice! 

This book is also available online with an active illinois.edu email address. It provides over 100 hands-on exercises to help you to gain practice in choosing effective visuals, keeping your visualizations clean, and telling a story.  

Scholarly Commons also provides access to various software that can be accessed on the computers in Main Library room 220. These tools can also be accessed through UIUC Anyware. Useful software for data storytelling includes: 

  1. Tableau Public

Tableau is a popular data visualization tool with many features useful for making many types of visualizations, such as histograms, pie charts, and boxplots. Tableau also allows users to create dashboards which create a comprehensive story by combining visuals and data.

If you have data you need to share with an audience, consider sharing it through a data story. Data stories are often more visually appealing and engaging than other methods of sharing data. The Scholarly Commons has lots of useful tools to help you create a data story! 

You can’t analyze data if you ain’t cute: Data Visualization

Meme from Reno 911 with the original text stating "You can't fight crime if you ain't cute" but the "fight crime" is crossed out and above is written "analyze Data"

Humans are highly visual creatures, even more so in our hyper-graphic world of ultra-filtered images and short aesthetic videos. Great ideas are ignored into oblivion in favor of shiny graphics and slick illustrations, so even data analysts need to be aware of how they present their findings. A well-designed infographic will be much more impactful, widely shared, and remembered than columns and rows of numbers. Even a simple graph can help people better come to conclusions and absorb information than they ever would with just numbers alone. People who can not only crunch numbers but also create stunning communications about those numbers are a real asset on the job market, so it behooves any hopeful data analyst to at least learn the basics of visualization.

While data analysis has existed in one form or another for centuries, its modern concept is highly tied to a digital environment, which means that people who are looking to move into the data science field will undoubtedly need some technology skills. In the data field, the primary coding languages include Python, R, and SQL. Software is a bit more complicated, with numerous different programs and services used depending on the situation, including Power BI, Spark, SAS, Excel, to name a few. While this is overwhelming, remember that it is not important to become an expert in all of the languages and software. Becoming skilled in one language and a few of the software options, depending on your interest or on the in-demand skills on job listings, will give you the transferable skills to quickly pick up the other languages and software as needed. If this still seems to be  an overwhelming prospect, remember that the best way to eat an elephant is one bite at a time. Take your time, break up the task, and focus on one step at a time!

There’s been a Murder in SQL City!

Detective faces board with files, a map and pictures connected with red string.

If you are interested in data or relational databases, then you have heard of SQL. SQL, or Structured Query Language, is designed to handle structured data in order to assist in data query, data manipulation, data definition and data access control. It is a very user-friendly language to learn with a simple code structure and minimal use of special characters. Because of this, SQL is the industry standard for database management, and this is reflected in the job market as there is a strong demand for employees with SQL skills.  

Enter SQL Murder Mystery

In an effort to promote the learning of this valuable language, Knight Labs, a specialized subsidiary of Northwestern University, created SQL Murder Mystery. Combining the known benefits of gamification and the popularity of whodunit detective work, SQL Murder Mystery aims to help SQL beginners become familiar with the language and have some fun with a normally dry subject. Players take on the role of a gumshoe detective tasked with solving a murder. The problem is you have misplaced the crime scene report and you now must dive into the police department’s database to find the clues. For true beginners with no experience, the website provides a walkthrough to help get players started. More experienced learners can jump right in and practice their skills. 

I’m on the case!

I have no experience with SQL but I am interested in database design and information retrieval, so I knew it was high time that I learn the basics. As a fan of both games and detective stories, SQL Murder Mystery seemed like a great place to start. Since I am a true beginner, I started with the walkthrough. As promised on the website, this walkthrough did not give me a complete, exhaustive introduction to SQL as a language, but instead gave me the tools needed to get started on the case. SQL as a language, relational databases and Entity Relationship Diagrams (ERD) were briefly explained in an approachable manner. In the walk through, I was introduced to vital SQL functions like “Select:, “Where”, wildcards, and “Between”. My one issue with the game was in the joining tables section. I learned later that the reason I was having issues was due to the tables each having columns with the same title, which is apparently a foundational SQL feature. The guide did not explain that this could be an issue and I had to do some digging on my own to find out how to fix it. It seems like the walkthrough should have anticipated this issue and mentioned it. That aside, By the end of the walkthrough, I could join tables, search for partial information matches, and search within ranges. With some common sense, the database’s ERD, and the new SQL coding skills, I was able to solve the crime! If users weren’t challenged enough with that task, there is an additional challenge that suggests users find the accomplice while only using 2 queries.

The Verdict is In

I really loved this game! It served as a great introduction to a language I had never used before but still managed to be really engaging. It reminded me of those escape room mystery boxes like Hunt a Killer that has users solve puzzles to get to a larger final solution. Anyone who loves logic puzzles or mysteries will enjoy this game, even if they have no experience with or even interest in coding or databases.  If you have some free time and a desire to explore a new skill, you should absolutely give SQL Murder Mystery a try!

Introductions: What is Data Analysis, anyway?

This post is part of a series where we introduce you to the various topics that we cover in the Scholarly Commons. Maybe you’re new to the field or you’re just to the point where you’re just too afraid to ask… Fear not! We are here to take it back to the basics!

So, what is Data Analysis, anyway?

Data analysis is the process of examining, cleaning, transforming, and modeling data in order to make discoveries and, in many cases, support decision making. One key part of the data analysis process is separating the signal (meaningful information you are trying to discover) from the noise (random, meaningless variation) in the data.

The form and methods of data analysis can vary widely, and some form of data analysis is present in nearly every academic field. Here are some examples of data analysis projects:

  • Taylor Arnold, Lauren Tilton, and Annie Berke in “Visual Style in Two Network Era Sitcoms” (2019) used large-scale facial recognition and image analysis to examine the centrality of characters in the 1960s sitcoms Bewitched and I Dream of Jeannie. They found that Samantha is the distinctive lead character of Bewitched, while Jeannie is positioned under the domination of Tony in I Dream of Jeannie.
  • Allen Kim, Charuta Pethe, Steven Skiena in “What time is it? Temporal Analysis of Novels” (2020) used the full text of 52,183 fiction books from Project Gutenberg and the HaithiTrust to examine the time of day that events in the book took place during. They found that events from 11pm to 1am became more common after 1880, which the authors attribute to the invention of electric lighting.
  • Wouter Haverals and Lindsey Geybels in “A digital inquiry into the age of the implied readership of the Harry Potter series” (2021) used various statistical methods to examine whether the Harry Potter books did in fact progressively become more mature and adult with successive books, as often believed by literature scholars and reviewers. While they did find that the text of the books implied a more advanced reader with later books, the change was perhaps not as large as would be expected.

How can Scholarly Commons help?

Holiday Data Visualizations

Posted on by

The fall 2020 semester is almost over, which means that it is the holiday season again! We would especially like to wish everyone in the Jewish community a happy first night of Hanukkah tonight.

To celebrate the end of this semester, here are some fun Christmas and Hanukkah-related data visualizations to explore.

Popular Christmas Songs

First up, in 2018 data journalist Jon Keegan analyzed a dataset of 122 hours of airtime from a New York radio station in early December. He was particularly interested in discovering if there was a particular “golden age” of Christmas music, since nowadays it seems that most artists who release Christmas albums simply cover the same popular songs instead of writing a new song. This is a graph of what he discovered:

Based on this dataset, 65% of popular Christmas songs were originally released in the 1940s, 50s, and 60s. Despite the notable exception of Mariah Carey’s “All I Want for Christmas is You” from the 90s, most of the beloved “Holiday Hits” come from the mid-20th century.

As for why this is the case, the popular webcomic XKCD claims that every year American culture tries to “carefully recreate the Christmases of Baby Boomers’ childhoods.” Regardless of whether Christmas music reflects the enduring impact of the postwar generation on America, Keegan’s dataset is available online to download for further exploration.

Christmas Trees

Last year, Washington Post reporters Tim Meko and Lauren Tierney wrote an article about where Americans get their live Christmas trees from. The article includes this map:

The green areas are forests primarily composed of evergreen Christmas trees, and purple dots represent Choose-and-cut Christmas tree farms. 98% of Christmas trees in America are grown on farms, whether it’s a choose-and-cut farm where Americans come to select themselves or a farm that ships trees to stores and lots.

This next map shows which counties produce the most Christmas trees:

As you can see, the biggest Christmas tree producing areas are New England, the Appalachians, the Upper Midwest, and the Pacific Northwest, though there are farms throughout the country.

The First Night of Hanukkah

This year, Hanukkah starts tonight, December 10, but its start date varies every year. However, this is not the case on the primarily lunar-based Hebrew Calendar, in which Hanukkah starts on the 25th night of the month of Kislev. As a result, the days of Hanukkah vary year-to-year on other calendars, particularly the solar-based Gregorian calendar. It can occur as early as November 28 and as late as December 26.

In 2016, Hannukah began on December 24, Christmas Eve, so Vox author Zachary Crockett created this graphic to show the varying dates on which the first night of Hannukah has taken place from 1900 to 2016:

The Spelling of Hanukkah

Hanukkah is a Hebrew word, so as a result there is no definitive spelling of the word in the Latin alphabet I am using to write this blog post. In Hebrew it is written as חנוכה and pronounced hɑːnəkə in the phonetic alphabet.

According to Encyclopædia Britannica, when transliterating the pronounced word into English writing, the first letter ח, for example, is pronounced like the ch in loch. As a result, 17th century transliterations spell the holiday as Chanukah. However, ח does not sounds like the way ch does when its at the start of an English word, such as in chew, so in the 18th century the spelling Hanukkah became common. However, the H on its own is not quite correct either. More than twenty other spelling variations have been recorded due to various other transliteration issues.

It’s become pretty common to use Google Trends to discover which spellings are most common, and various journalists have explored this in past years. Here is the most recent Google search data comparing the two most commons spellings, Hanukkah and Chanukah going back to 2004:

You can also click this link if you are reading this article after December 2020 and want even more recent data.

As you would expect, the terms are more common every December. It warrants further analysis, but it appears that Chanukah is becoming less common in favor of Hanukkah, possibly reflecting some standardization going on. At some point, the latter may be considered the standard term.

You can also use Google Trends to see what the data looks like for Google searches in Israel:

Again, here is a link to see the most recent version of this data.

In Israel, it also appears as though the Hanukkah spelling is also becoming increasingly common, though early on there were years in which Chanukah was the more popular spelling.

I hope you’ve enjoyed seeing these brief explorations into data analysis related to Christmas and Hanukkah and the quick discoveries we made with them. But more importantly, I hope you have a happy and relaxing holiday season!
