* http://www.leansigmamart.com Starting with understanding the DMAIC method, with out this you are never going to have successful results. I recently discovered this site dedicated to answering all the Lean Six Sigma / process improvement needs and questions. They offer a FREE very complete software system that will walk you through the entire DMAIC methodology. It has a training video at every possible step including example data, video demonstration, voice guided instructions, templates for every step, and a phone contact to even help you. Oh and did i say FREE? In that site they also have a forum for Q. & A. beside a live chat room. Do you use minitab? How about a complete section on how to use it with videos and links to their home page. They have so much more I cant list, just go there and see. I spend countless hours looking for answers as you did here. I found a source with accurate information and gives you what you are really looking for, plus a way to drive your projects with a mentor.

Statistical analysis is essential to identifying the critical factors in simulation. Performing the analysis of variance is to ensure the proper selection of significant factors. With this, understanding and judgment become more effective in making appropriate decisions regarding the product and process designs. The purpose of statistical analysis is to determine the normal (probable) behavior of a simulation and distinguish it from abnormal (improbable) behavior of a system. In other words, we want to distinguish what happens commonly from what merely happens by chance. For example, if our simulation models traffic and a truck flips over on the freeway, a statistical analysis would determine whether such an accident happens often or if this was simply an unlucky day for the driver and the accident happened by chance.
A 'spot check" is a random sampling to gather infiormation to determine an outcome or on which to base an action. (For instance: Police may conduct random 'spot checks' of motorists to determine their compliance with having proper insurance, vehicle registrations, or drivers licenses in their possession.)

Statistics and Logic - the political theorist must possess a broad scientific background and a knowledge of current political problems, and he must employ scientific methods in gathering and evaluating data and in drawing conclusions. These involve a proper application of statistical procedures for the quantitative measurement of social phenomena and of logical procedures for the analysis of reasoning.
role of statistic would be more general to every one as there will be proper statistical figures
