Hypothesis Sample Case Science! Conclusion? Bibliography | Sample Case One way to test whether this is an effective model would be to take several examples of perceivable change from our history and see what they suggest given these equations. So which ones should we use? We want to pick examples in which we can be reasonably certain that some perceivable change actually occurred. I am going to specifically use the civil rights movement in the 1950's and the 1960's as my sample case. Need Factors
As we can see there are many need factors and many actual changes. From just, "the look", of things the information seems to suggest a heat engine existing at a high hot to cold difference, or in our case, a vast difference in opinion across the United States. In fact if we calculate the engine's maximum efficiency and actual efficiency using just the number of reasons to want change we get ... Desire to change = 5, Least desire = 0; Efficiency = 1-(0/5) = 1.0 Change = 4, Effort = 5; Maximum Efficiency = 4/5 = 0.8 As you can see our engine is operating within its maximum efficiency, but this model is still pretty crude. All we did was add the items together with no effort to actually weigh them. The reason maximum efficiency is 1.0 is because of the assumption that the lowest desire for change is just whoever is unaffected by the five need factors we listed. If the minimum number of factors that could affect any individual were higher our efficiency would actually be lower. | |
