Here’s what happens to regression 📈 when sample sizes are low…
even with a strong underlying correlation, sampling error will erode everything! 🧪 ‼️

in #regression, noise is assumed independent—but none of that matters when sample sizes are low…
here the #correlation remains approximately the same at -0.065 irrespective of noise 🦖, but will range from -1 to 1 with small samples
