if you can send me a diagram of how it works, i#m afraid i dont know what you mean by scissor lift.....

No, he really meant statics. Statics is the science of computing forces in things that are not accelerating. It is also useful if you are dealing with motion that is slow enough to be considered static. The essence of Statics is found in the basic equation: the sum of the forces = 0. When you design a bridge you use statics. When you design a slow moving arm, you use statics. When you design a fast moving arm (One where you get a significant amount of "whip") you use Dynamics.

Stats is usually short for Statistics, the science of making sense of large amounts of individually useless data.

BTW a scissors lift is a non-trivial statics problem.
