In statistics, the capital letter “N” is used to represent the total number of observations or the size of the population (i.e.) N is the total number of cases in all groups whereas the small letter “n” represents the sample size. That is, we can explain N simply as it is the number of elements in a population.

In calculus and most other branches of mathematics beyond practical geometry, angles are measured in radians. This is because radians have a mathematical naturalness that leads to a more elegant formulation of some important results.
What does Σx mean in math?
Radians measure angles by distance traveled. or angle in radians (theta) is arc length (s) divided by radius (r). A circle has 360 degrees or 2pi radians — going all the way around is 2 * pi * r / r. So a radian is about 360 /(2 * pi) or 57.3 degrees.

The Plus/Minus stat is a calculation of your team's net points while a player is on court. For example, if a player was on court the whole game and your team won 50-48, their Plus/Minus would be +2 for the game. Plus/Minus can tell you which lineups are working well and when you might want to switch up some rotations.
