Stanford just made a $200,000 AI degree free.
No application.
No tuition.
No “elite access”.
Stanford released its actual AI/ML curriculum on YouTube.
Not a PR-friendly intro.
Not “AI for the public”.
This is the real thing.
The same lectures shaping people working on frontier models.
What just became public:

The uncomfortable truth:
The degree isn’t the scarce asset anymore.
Execution speed is.
Top schools know this.
That’s why they’re publishing the playbook.

Did you know you can calculate the exact sample size you need before you even start your study? A sample size calculation — also called a power analysis — helps you determine the optimal number of observations for your statistical analysis. It ensures your study is large enough to detect meaningful effects, but not so large that you waste resources.
Key advantages of performing a power analysis:
✔️ Avoid underpowered studies that might miss real effects
✔️ Save time and costs by avoiding unnecessarily large samples
✔️ Tailor your sample size to the effect size you care about detecting
✔️ Choose your desired confidence level and statistical power for robust results
✔️ Works for a wide range of statistical tests, from t‑tests to ANOVA and regression
✔️ Supported by many free R packages, such as pwr
The image shows on the left side how the required sample size changes depending on the expected effect size — smaller effects require much larger samples. On the right side, you see an example of a calculated sample size for comparing two groups using a t-test, showing exactly how many participants are needed per group for the desired confidence level and statistical power.
