Step 2: Week 5 Reflection
This week I learned what a simulation model is and how a distribution model is used in running simulations. I learned that a distribution can be continuous (meaning all continuous values in a distribution range) or discrete (meaning a discrete set of values in a distribution range). I learned how to use the RISK tools in excel to run a simulation which I captured the output above. I learned about the flaw of averages and how it impacts simulations. I also learned how the input variables distribution varies allow for multiple simulation runs or scenarios.
This week’s assignments took me about 8-10 hours.
