Understanding Sample Standard Deviation 

The formula to compute the standard deviation from a sample of data looks complex - ugly even. But understanding the the notion of variation (e.g., standard deviation) is fundamental to statistical thinking. At its core, the computation for sample standard deviation is very sensible (like so many other complex-appearing mathematical formulas, e.g., the distance …

Assumptions in Geometric Probability  ☆

Geometric probability makes use of measurement to determine probabilities. For example, the probability of hitting a bullseye could be found by computing the ratio of the area of the bullseye (4π in^2) and the area of the entire dart board (64π in^2), which is 4/64 = 0.0625; or the probability of breaking a stick randomly …
