In my first post on exploratory data analysis (EDA), I discussed why it’s important to get a “sense” for the data you’re working with before applying analytical techniques that may come with critical assumptions and prerequisites.
In this post, I’ll expand on the concepts I discussed in that post and also examine some other exploratory techniques. The goal is to make you familiar with various forms of data analysis so you can use them to make the right decisions for your organization.
We humans like pictures. We’re wired to process images quickly and effectively.
The evolution of those capabilities over thousands of years has allowed us to survive by detecting and evading predators, finding forage, and excelling as predators ourselves. To support these activities and others, the image processing capabilities of our brains have become especially adept at distinguishing basic shapes, such as lines, circles and various polygons, as a precursor to fully comprehending what the actual imagery represents.
We are also capable of understanding complex concepts, abstractions and relationships. But not all of us are created equal in that respect – at least judging from the distribution of scores on the math component of college prep exams! But even the savants among us reach a limit as the volume of data and complexity of problems become intractable to the human mind.
And though we may differ in our analytical abilities, we do seem to share one thing: our ability to reason visually plays an important role in our problem solving. Let’s examine this in the latest “Practical Analysis” blog post. (more…)
You only get one chance to make a first impression. Sound advice for socialization, sure, but it can also apply to the world of higher ed. (Beyond the chats at the water cooler, that is.) It is advice that might be heeded during a professor’s first class of the semester…or maybe even the first few minutes of every lesson that professor is teaching.
But it can also be applicable to the technology an institution of higher education is using. Many colleges and universities are increasingly using data for a number of purposes – to increase retention, to identify and help struggling students, or to make processes more efficient, to name just a few. A data dashboard can help or hinder the analytics process. It is the first impression a user gets with the data, and if it is too clumsy to navigate, a user might not come back to work with the data in a meaningful way. If it is easy to use, it could benefit everyone in the community. Here is some advice about how to find success with dashboards, and what makes a good dashboard in the first place. (more…)
Every year, thousands of children are hospitalized because of the flu; several dozen to more than 100 children die each year from complications.
Tweet: How analytics can help during flu outbreaks
It’s important for health providers not only to know which children need to be vaccinated, but also to understand where there are flu outbreaks and how they might need to readjust their staffing to deal with surges in flu patients. How can they do so? Let’s take a look. (more…)
If you think about it for a moment, the purpose of visualizations is to communicate information effectively. And you want to do that in ways that brings out patterns and trends that can’t be seen just by looking at tables of numbers. Ideally, this is going to be something that is aesthetically pleasing. You can have a positive emotional response when you look at some of these displays and engage users more, so they are willing to really dig in to analyze data.
Tweet: How you can better visualize your data
In this article, we’ll review some of Dimensional Insight’s Chart portlet visualizations in order to illustrate a wide variety of ways to visualize data. I think you’ll see that with all of the options available, it is easy to communicate information in a way that is both effective and pleasing to the eye. (more…)
Healthcare analytics. Data visualization. Population health. Buzz continues to build around these terms as we look ahead to 2018. But looking back, we find a surprising figure at the root of all three: Florence Nightingale.
Tweet: Four Lessons from the Mother of Healthcare Analytics
Florence Nightingale, the mother of modern nursing, was also arguably the mother of healthcare analytics. She was a trailblazer in using statistics to identify preventable conditions that affect mortality and a master of data visualization. Her story has powerful lessons for today’s analysts. Here are four. (more…)
2017 was a busy and tumultuous year for the beverage alcohol industry, especially those who were affected by the wildfires in California. This year also brought many company mergers and consolidations, continuing an ongoing trend in the industry.
Tweet: Holiday wish list for the beverage alcohol industry
What’s clear as we head into 2018 is that technology and analytics are becoming even more important than ever, and it’s important for the beverage alcohol industry to adopt tools that will lead to improved efficiency, increased productivity, and more revenue. With that in mind (and since the holidays are on our minds), I created a holiday wish list for better business intelligence and analytics in the beverage alcohol industry. (more…)
As an analyst, you can perform the most sophisticated analysis and draw the most compelling conclusions, but without a way to share these with others, your hard work stays with you. So how to best communicate when it comes to quantitative data? In a nutshell: words and pictures.
