1. ### I have a Mean and Standard Deviation. If I multiply the Mean by a number (non-constant), do I have to multiply the Standard Deviation by that number?

Let me explain the project more fully. The model I made is a Monte Carlo Simulation (10,000 times) and is used to show two teams playing each other and the probability of either one winning. Winner is determined by who has a higher final score for each simulation Here’s what I do: I collect...

If I multiply the STD Deviation by .85, the STD Deviation of course decreases. But I want to make sure that makes sense. My plan is to run a Monte Carlo simulation. If I increase or lower my variability, it's going to widely change my predicted Runs Score over a simulation of 10,000 times. Does...

Hello! I'm making an MLB Model and I'm at a point where I'm stuck. I have the AVG Runs Scored for each team, and the Standard Deviation of Runs Scored for each team for the season as well. If I know that one team is facing a pitcher who is superb, let's say 15% better than the league average...
