What episode of Back to Statistics does Hilary talk about statistical significance?
In episode #77 - Back to Statistics they talk about the significance of statistical significance. The episode was prompted by a recent Nature article which (once again) calls for the removal of p-values from all of science. Hilary and Roger’s thoughtful back-and-forth helps frame both the importance and the over-reliance of p-values. However, Roger gives great insight in comparing the epidemiologist Sander Greenland (an author of the Nature article) with the reaction of John Ioannidis (physician-scientist). The insight is that those who advocate getting rid of p-values are often quite concerned with type II errors; indeed the Nature article expresses concerns of missed effects. Ioannidis, on the other hand, is troubled by type I errors and the idea that across the board, false positives dominate the scientific literature.
What episode of Stitch Fix does Hilary talk about data science?
In episode #34 - F Dist Hilary and Roger discuss the massive data science team at Stitch Fix and how the different data science tasks are all important to create the end product. Recently the Stitch Fix algorithms team put together a visualization describing the algorithm for how data science is used to choose clothing for their clients. By using the scrollytelling software, the technical details are made accessible to data scientists at all levels (including those in an introductory data science course). Additionally, the breadth of methods is laid out to demonstrate both how varied the work can be and how broad data science skills (either for an individual to have or for a group to exhibit together as a team) are necessary for successfully working with data. Some of the data science topics they describe include:
