Question

When setting up a multi-criteria analysis, why would you use the scale from 1-100 to define your scoring system?

a) it gives more granularity and variability in the overall scores
b) you would be able to give points without skewing results
c) both a and b
d) you wouldn't - it is always better to score from 1-10

Answer 1

Using a scale from 1-100 in a multi-criteria analysis provides more granularity and variability in the overall scores and allows you to give points without skewing the results.

Step-by-step explanation:

When setting up a multi-criteria analysis, using a scale from 1-100 to define your scoring system has several advantages. One reason is that it gives more granularity and variability in the overall scores. For example, if you have two options that are very close in their scores, using a scale of 1-10 may not allow you to accurately differentiate between them. However, with a scale of 1-100, you can assign scores that reflect smaller differences between the options.

Another reason to use a 1-100 scale is that it allows you to give points without skewing the results. If you use a smaller scale, such as 1-10, each point assigned will have a larger impact on the overall score. This can lead to some criteria or options having disproportionate influence on the overall results.

Therefore, the correct answer is c) both a and b. Using a scale from 1-100 provides more granularity and variability in the overall scores, and allows you to give points without skewing the results.
