How to evaluate how the survey uses ratios to reach conclusions?

A ratio is by principle a mathematical relation in comparison and it is expressed by two numbers divided by a colon where the first one stablishes the numerical relation according to the second one in a whole; e.g.: if our object of study is the racial mix of the population of a specific geographic location and one of the findings of our survey is that there are 98 dark skinned people and 14 clear skinned people in that location, the ratio of d.s. people to w.s. people is 98:14 or 14:1, which ultimately is the same.

How to evaluate how the survey uses ratios to reach conclusions will depend on what the objective of the survey is. If the interpretation of the information obtained in those ratios is useful to the ultimate objective of the survey, then the use of it is correct.
