### Questions

**1)** Can you describe the word 'Fewer' ?

**2)** Can you describe what a Weighted Average is ?

**3)** What is Standard Deviation ?

**4)** What is the Sharpe Ratio ?

**5)** What is R squared ?

**6)** Can you give the names of some measures of central tendency ?

**7)** Can you give the names of some measures of dispersion ?

**8)** Can you describe Brownian Motion ?

This is the random motion of particles in a fluid resulting from their collision with the fast moving atoms in the fluid.

This is a continuous-time random (stochastic) process and it is a limit of both simpler and more complicated random processes (random walk and Donsker theorem)

Brownian motion is described by the wiener process

**9)** Can you describe Geometric Brownian Motion ?
