Standard Deviation
A measure of how spread out a set of values is from their average. A low standard deviation means results cluster tightly around the mean, while a high one means they're scattered widely.
Think of it like weather: two cities can average 70°F, but one ranges from 65-75 while the other swings from 50-90.
Why it matters
It tells you how volatile a player's performance is — a 20-point scorer with a standard deviation of 2 is far more predictable than one with a standard deviation of 8.
How DMP uses this
DMP calculates per-stat standard deviation from recent game logs to build variance estimates, which directly feed into P(over) calculations for every prop.
Common mistake
Assuming a player with a high average is always a safe bet — the spread around that average matters just as much.
