One potential benefit of online surveys is the use of “conditional branching.” In conventional paper and pencil surveys, one question might ask if the respondent has shopped for a new car during the last eight months. If the respondent answers “no,” he or she will be asked to skip ahead several questions—., going straight to question 17 instead of proceeding to number 9. If the respondent answered “yes,” he or she would be instructed to go to the next question which, along with the next several ones, would address issues related to this shopping experience. Conditional branching allows the computer to skip directly to the appropriate question. If a respondent is asked which brands he or she considered, it is also possible to customize brand comparison questions to those listed. Suppose, for example, that the respondent considered Ford, Toyota, and Hyundai, it would be possible to ask the subject questions about his or her view of the relative quality of each respective pair—in this case, Ford vs. Toyota, Ford vs. Hyundai, and Toyota vs. Hyundai.
Then, CWSS was used to evaluate each voter's assessment of a nominee, filling in the appropriate weights for prevalence, importance, and likelihood of exploit; the remaining 15 factors were all assigned ""Not Applicable" values, which reduces the impact of those factors on the final score. Due to how the CWSS formula is constructed, the use of "Not Applicable" values required a one–step normalization of a raw score to produce a final score that fell within the range of 0 and 100. In the CWSS formula, with the three active factors, the final score is most affected by importance, then prevalence, then likelihood of exploit.
These words conclude the novel and find Nick returning to the theme of the significance of the past to dreams of the future, here represented by the green light. He focuses on the struggle of human beings to achieve their goals by both transcending and re-creating the past. Yet humans prove themselves unable to move beyond the past: in the metaphoric language used here, the current draws them backward as they row forward toward the green light. This past functions as the source of their ideas about the future (epitomized by Gatsby’s desire to re-create 1917 in his affair with Daisy) and they cannot escape it as they continue to struggle to transform their dreams into reality. While they never lose their optimism (“tomorrow we will run faster, stretch out our arms farther . .”), they expend all of their energy in pursuit of a goal that moves ever farther away. This apt metaphor characterizes both Gatsby’s struggle and the American dream itself. Nick’s words register neither blind approval nor cynical disillusionment but rather the respectful melancholy that he ultimately brings to his study of Gatsby’s life.
