单纯随机抽样(simple random sampling) 相关知识点: 试题来源: 解析 单纯随机抽样:这种方法的基本原则是每个抽样个体被抽中选人样本的机会是相等的,也即把目标人群中的每一个个体都作为抽样的对象。简便、易行的科学抽样方法是利用随机数字表。单纯随机抽样首先要有一份所有研究对象排列成序的编号名单,再用随机的方法...
简朴随机抽样(simple random sampling) 相关知识点: 试题来源: 解析 简单随机抽样也称为简朴随机抽样(simple random sampling)单纯随机抽样、纯随机抽样、SRS抽样,是指从总体N个单位中任意抽取n个单位作为样本,使每个可能的样本被抽中的概率相等的一种抽样方式。

简单随机抽样(Simple random sampling) 简单随机抽样也称为单纯随机抽样、纯随机抽样、SPS抽样 ,是指从总体N个单位中任意抽取n个单位作为样本, 使每个可能的样本被抽中的概率相等的一种抽样方式. 简单随机抽样是其它抽样方法的基础,因为它在理论上最容易处理, 而且当总体单位数N不太大时,实施起来并不困难.但在实际...

Simple random sampling differs from both cluster sampling types as the selection of the sample occurs from the total population, not the randomly selected cluster that represents the total population. In this way, simple random sampling can provide a wider representation of the population, while clus...
The use of simple random sampling removes all hints ofbias—or at least it should. Because individuals who make up the subset of the larger group are chosen at random, each individual in the large population set has the same probability of being selected. In most cases, this ...
simple random sampling:A sample of n subjects is selected in such a way that every possible sample of the same size n has the same chance of being chosen 相关知识点: 试题来源: 解析 简单随机抽样:由N个个体组成的样本,每个个体都是从具有相同样本容量N和相同几率被抽取的样本中选出 ...
For this reason simple random sampling is more commonly used when the researcher knows little about the population. If the researcher knows more, it is better to use a different sampling technique, such as stratified random sampling, which helps to account for the differences within the population...
