The most recent data from the National Survey of Family Growth (NSFG) provides a first look at people born in the 2000s as young adults and an updated view of people born in the 1990s at the peak of their child-bearing years. Compared to previous generations at the same ages, these cohorts have fewer children, and they are less likely to say they intend to have children. Unless their plans change, trends toward lower fertility are likely to continue for... Read More Read More The post Young Adults Want Fewer Children appeared first on Probably Overthinking It.
This is the last in a series of excerpts from Elements of Data Science, now available from Lulu.com and online booksellers. This article is based on the Recidivism Case Study, which is about algorithmic fairness. The goal of the case study is to explain the statistical arguments presented in two articles from 2016: Both are about COMPAS, a statistical tool used in the justice system to assign defendants a “risk score” that is intended to reflect the risk that they...

This is the fifth in a series of excerpts from Elements of Data Science, now available from Lulu.com and online booksellers. It’s based on Chapter 16, which is part of the political alignment case study. You can read the complete example here, or run the Jupyter notebook on Colab. Because this is a teaching example, it builds incrementally. If you just want to see the results, scroll to the end! Chapter 16 is a template for exploring relationships between political...

This is the fourth in a series of excerpts from Elements of Data Science, now available from Lulu.com and online booksellers. It’s from Chapter 15, which is part of the political alignment case study. You can read the complete chapter here, or run the Jupyter notebook on Colab. In the previous chapter, we used data from the General Social Survey (GSS) to plot changes in political alignment over time. In this notebook, we’ll explore the relationship between political alignment and... Read More Read More The post Political Alignment and Outlook appeared first on Probably Overthinking It.
The premise of Think Stats, and the other books in the Think series, is that programming is a tool for teaching and learning — and many ideas that are commonly presented in math notation can be more clearly presented in code. In the draft third edition of Think Stats there is almost no math — not because I made a special effort to avoid it, but because I found that I didn’t need it. For example, here’s how I present...

Despite the hype, it’s been surprisingly challenging to find quantum algorithms that outperform classical ones. In this episode, Ewin Tang discusses her pioneering work in “dequantizing” quantum algorithms — and what it means for the future of quantum computing.

It is generally accepted that the transition from hunter-gatherer communities to agriculture was the single most important event in human history, ultimately giving rise to all of civilization. The transition started to take place around 12,000 years ago in the Middle East, China, and Mesoamerica, leading to the domestication of plants and animals, a stable […] The post The Transition to Agriculture first appeared on NeuroLogica Blog.
A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to rewrite notions of time and evolution. The post Why Everything in the Universe Turns More Complex first appeared on Quanta Magazine
