仅当您正在设计特定于该个体的某些东西（例如假肢）时，拥有单个个体的人体测量数据才有用。 真正的力量来自拥有一个人口统计数据集，这基本上是对很多人的度量。 如果您拥有上述人口中具有统计意义的重要部分的数据，则可以推断出您没有的数据。 因此，通过统计数据，您可以测量人口数据集中的几个人，并且具有足够的知识来高度准确地确定其他人的状况。 此过程类似于民意测验人员用来确定可能的选举结果的方法。 人口可以像“男人”一样笼统，代表世界上所有种族和国家的所有男性，也可以针对诸如“高加索美洲男人”这样的人口稠密的人群量身定制。
英国兰卡斯特大学统计Essay代写：人口统计数据
Having anthropometric data for a single individual is only useful if you are designing something that is specific to that individual, such as a prosthetic limb. The real power comes from having a demographic data set, which is basically a measure for many people. If you have data for a statistically significant portion of the above population, you can infer data that you do not have. So with statistics, you can measure several people in a demographic dataset and have enough knowledge to determine the status of others with high accuracy. This process is similar to the method used by pollsters to determine possible election results. The population can be as general as “men”, representing all men in all races and countries in the world, or it can be tailored for densely populated people such as “Caucasian American men”.
