Bayes Theorem gives us a way of updating our beliefs in light of new evidence, taking into account the strength of our prior beliefs. Deploying Bayes Theorem, you seek to answer the question: what is the likelihood of my hypothesis in light of new evidence?
In this article, we’ll talk about three ways that Bayes Theorem can improve your practice of Data Science:
By the end, you’ll possess a deep understanding of the foundational concept.
Bayes Theorem provides a structure for testing a hypothesis, taking into account the strength of prior assumptions and the new evidence. …
There are many types of statistical tests — null hypothesis significance testing predominates.
With this technique, the objective is to test an observation against the null hypothesis. You can think of the null hypothesis as the status quo. It represents the situation where the intervention does not work.
Significance testing rose to preeminence because it is a useful way to draw inference over a subset of data drawn from a larger population. This article will enhance your intuition about this useful data science technique.
The goal of the researcher conducting the null hypothesis test is to evaluate whether or not…
The distribution of data refers to the way the data is spread out. In this article, we’ll discuss the essential concepts related to the normal distribution:
Data distribution is of great importance in statistics because we are pretty much always sampling from a population where the full distribution is unknown. The distribution of our sample may put limitations on the statistical techniques available to us.
🎓 Codecademy — time after time, I find myself recommending this powerful learning platform to folks breaking into coding or looking to pick up new languages. The strength of Codecademy lies in its simplicity — these exercises will get your muscle memory trained up so that you’ll be typing code like a master in no time.
🖌 The Data Visualization Catalogue — this site offers archetypal renderings of all the creative chart options available to help you…
In Stephen Covey’s masterful 7 Habits of Highly Effective People, the seventh habit is “sharpen the saw.” This refers to enhancing our assets to seek continuous improvement in our work. As Abe Lincoln said,
Give me eight hours to chop down a tree, and I will spend the first six sharpening the saw.
Better tools to structure, simplify, and broaden our Data Science work will make us more effective thinkers, decisionmakers, and practitioners.
In this article, we’ll explore how to sharpen our Data Science saws — and also investigate the unanswered question of who is handing out saws to so…
Through unsupervised learning, a data scientist can explore an unlabeled dataset to produce categories or clusters. You can use this technique to create a neighborhood explorer tool to help residents and visitors develop an understanding of points of interest near where you live.
You can use a publicly available points of interest dataset like I did, or you could scrape data from Yelp or TripAdvisor.

I was inspired to create this project based on my interest in GIS data and my love of Washington, DC, where I went to…
This article will help you understand the whys and hows of implementing better data management practices at your organization.
In 2020, the size of our digital universe is 40 zettabytes. By comparison, the world had produced just 1.2 zettabytes of data by the year 2010. That represents explosive growth of 3,000% in a single decade. Obviously, this presents both opportunities and challenges.
In The Lean Startup, Eric Ries explores how innovation leaders use data to support experimentation. A strong data infrastructure allows an organization to validate hypotheses about customer values. …
2020 has been a rough year. Amidst the pandemic, economic fallout, quarantine orders, racial reconning, a stressful U.S. election, holidays spent separated from loved ones, important milestones passed without the recognition they deserved, and other deeply tragic circumstances — something troubling happened to me.
I lost my jeans.
After six months of Teams calls wearing athletic shorts under a nice top, it had come time to break out the smart-casual dark wash staple to wear to an outdoor happy hour.
I could not find them anywhere. I looked in each box in storage, then in every closet in the house…
COVID-19 accelerated the end of 20th-century trends and entrenched the dominance of 21st-century paradigms. For millions around the world, the pandemic response will forever shape the way we work, where we chose to live, and how we engage in commerce.
I’m telling everyone to update their model. You should really only use data since COVID if possible.
Dr. Carl gold, former Wall Street quantitative analyst turned Chief Data Scientist and author of Fighting Churn with Data, urges Data Scientists to rethink their approach to modeling customer behavior due to model drift, which occurs when the training dataset no longer faithfully…
With Python’s straightforward, human-readable syntax, anyone can access impressive capabilities for scientific computing. Python has become the standard language for data science and machine learning, and it was rated in the top three most loved languages in Stack Overflow’s 2020 Developer Survey.
If you’re a newcomer to this much loved programming language, here are ten tips to promote the flourishing of your Python skillset. You can follow along in this Google Colab notebook (plus, a quick video introduction to Google Colab).
A simple, single-line syntax for working with lists, a list comprehension allows you to access and perform an action…
