New York City’s Noise Landscape. Apodcast? E.K.O Legend · Data Speaks: Understanding NYC's Noise Landscape So, I’m sure you’ve heard of Google’s Notebook LM. If you haven’t, listen to the podcast above then come back. Seriously, I’ll wait. OK, Just press play and listen as you scroll through. Alright, now that you’re back, let me give you a brief background on why and how this started. For months, my teammates Andrea Lacche , Pradeep, and I have been working on analyzing New York City’s noise landscape as part of a class project( 311 Noise complaints data ). The goal was to analyze noise complaints across New York City to better understand the urban noise landscape. We wanted to identify key hotspots and trends, ultimately providing insights into how noise pollution affects different neighborhoods and what measures might be effective in addressing these issues. We uncovered some pretty interesting insights, such as the Bronx having the highest number of noise complaints, particul...

  Understanding Survival in the ICU: How Logistic Regression Reveals Key Insights Imagine you're in charge of an Intensive Care Unit (ICU). Every day, critically ill patients are admitted, each presenting unique health challenges. Your team’s goal is straightforward yet monumental: ensure the best possible outcomes for every patient. But how do you objectively understand which factors most impact survival rates? Enter logistic regression—an accessible yet powerful statistical tool that can help you make sense of complex medical data. Photo by Anna Shvets:  What Exactly is Logistic Regression? At its core, logistic regression is a statistical method used when the outcome you're interested in has two possible categories: such as survived versus not survived, or disease versus no disease. Instead of predicting exact values, logistic regression estimates the probability that an event will happen. For example, it can predict the likelihood that a patient admitted to the ICU will...

  Beauty in the Classroom: What Really Drives Professor Evaluations? ( A data-driven exploration ) A data-driven exploration of how appearance, gender, and other factors influence teaching evaluations Photo by Max Fischer We’ve all been there at the end of a semester: faced with those standardized evaluation forms asking us to rate our professors. Most universities consider these evaluations essential for tenure decisions, promotion, and even annual performance reviews. But what factors are truly being measured in these evaluations? Are they valid indicators of teaching effectiveness, or are they influenced by factors entirely unrelated to a professor’s teaching abilities? In this article, I’ll dive into an analysis of real evaluation data from the University of Texas at Austin to uncover what’s actually driving student ratings. The results may surprise you ,and make you think differently about those evaluation forms. The Dataset: Beauty and the Professor The data comes f...

  Decoding the Numbers: How Linear Regression Reveals Hidden Relationships image by Artem Podrez Have you ever wondered if taller people really do have broader shoulders? Whether consuming more calories at Starbucks means consuming more carbs? Or if more attractive professors actually get better teaching evaluations? These are more than just idle questions. They touch on fundamental patterns in nutrition, human physiology, and even unconscious bias in education. Beneath these questions lies a powerful statistical tool that can help us uncover meaningful relationships in data: linear regression. In this article, we’ll explore how linear regression works, when to use it, and what it can tell us about the world around us. Using three real-world examples, we’ll see how this technique allows us to predict one variable from another and quantify just how strong these relationships really are. What Is Linear Regression, Really? At its heart, linear regression is a way to describe how ...

  Demystifying Linear Regression: A Simple Guide to Predicting Real-World Outcomes By Emmanuel Olimi Kasigazi Have you ever wondered how weather forecasters predict temperatures or how businesses forecast sales? At the heart of these predictions lies a simple yet powerful statistical tool known as linear regression. Linear regression might sound intimidating at first, but it's actually a straightforward method that helps us predict one variable based on another. Think of it as a tool that draws the "best-fit line" through data points, helping us understand trends and predict future values. What Exactly is Linear Regression? In simple terms, linear regression explores the relationship between two variables by fitting a straight line through data points. One variable is considered independent (predictor), and the other is dependent (response). For instance, predicting ice cream sales based on temperature: temperature is your predictor, and ice cream sales are the respo...

  Mapping Freedom: Insights from the Human Freedom Index What exactly do we mean when we talk about freedom? Is it the ability to speak your mind without fear? The assurance that laws will be applied fairly? The right to practice your faith without interference? Or perhaps the opportunity to start a business without excessive red tape? Freedom is complex, multifaceted, and often difficult to quantify. That's where the Human Freedom Index (HFI) comes in—a collaborative effort by the Cato Institute, the Fraser Institute, and the Liberales Institut that attempts to measure freedom across countries through a variety of variables, from political rights to economic indicators. In this article, I'll take you on a journey through the relationships between different aspects of freedom, sharing insights from an analysis of the Human Freedom Index data from 2008-2016. We'll explore how these freedoms correlate, what this tells us about societies around the world, and why some of the f...

We're not courageous, we're fearful We fear for our future generations' being We fear for our children's future We're fearful of incompetent dictators We are fearful of the systems that failed us We're fearful of the leaders we elected who take advantage We fear the lack of education and ignorance that looms among us We are fearful of the mediocrity that drives us We are fearful of the insanity we have normalized We are fearful of environments where wrong is right, Where right is seen as wrong We are fearful for our future wives We are fearful of our futures, period We fear for our lives And I, personally, was fearful of never becoming All I could be

  Statistical Analysis in the Real World: How Education Impacts Work Hours Do people with higher levels of education work more hours? It’s a question with significant implications for career planning, economic mobility, and work-life balance decisions. Using rigorous statistical analysis techniques, we can move beyond anecdotes and explore what the data actually tells us. distributions of hours worked by educational attainment and relevant summary statistics The Data: Education and Work Hours The General Social Survey collects comprehensive data on US residents, including their educational attainment and weekly work hours. Our analysis examined 1,172 respondents across five educational categories: A surface-level examination of these numbers might suggest a pattern: those with Bachelor’s degrees work nearly four more hours weekly than those without high school diplomas. But is this difference statistically significant , or could it be due to random chance? Statistical Ana...
