Sokal and Rohlf 4th edition - the best and most important statistical textbook available - in my humble opinion). Most students learn stats when they don’t need it, and then develop a loathing for it and forget it quickly. This is a big shame since statistics is really a way to explain what you are seeing in the world - clearly. Sokal and Rohlf fixes the problem. PS. YOU WILL GET IT CHEAPER FROM OTHER SOURCES.
