Learn the distinctions between simple and stratified random sampling. Understand how researchers use these methods to accurately represent data populations.

Researchers argue that, in some situations where machine-learning models are used to allocate scarce resources or opportunities, randomizing decisions in a structured way may lead to fairer outcomes.

Using MR-SPI and AlphaFold3, scientists unravel the molecular underpinnings of Alzheimer’s disease, identifying key protein changes that could reshape future treatments. Study: Deciphering proteins in ...
