Different Types of Data Sampling Methods and Techniques
2024年7月15日 Data sampling is a statistical method that involves selecting a part of a population of data to create representative samples The fundamental aim is to draw conclusions about the entire population without having to engage with every individual data point, thus saving time, resources, and effort while still achieving accurate resultsSampling is the statistical process of selecting a subset—called a ‘sample’—of a population of interest for the purpose of making observations and statistical inferences about that population Social science research is generally about inferring patterns of behaviours within specific populations We cannot study entire populations because of feasibility and cost constraints, Sampling – Social Science Research: Principles, Methods and 2022年10月27日 The sampling technique in quantitative research comes from its ability to draw small units of the population (ie, sample size) and generalize it to the population (Seddon Scheepers, 2012)In a study, specifically in behavioural research where the number of population elements is too large, collecting data from every element of a population is unrealSampling Techniques for Quantitative Research SpringerLink基本采样方法（Basic sampling method） 将随机变量进行映射：将简单的随机变量映射到desired的随机变量，从而完成采样。对于一维的随机变量，满足变换公式 p(y)=p(z)\left\frac{dz}{dy}\right 映射关系为y=f(z)，精心挑选映射关系，从而就能得到想要的概率 采样方法(Sampling Method) 知乎
