Therefore, a stratified random sampling procedure was created based on the Center for Disease Control and Prevention’s (CDC) Community Assessment for Public Health Emergency Responses (CASPER) sampling methodology . The CASPER approach was developed using cross-sectional epidemiological principles and is a form of a community needs assessment

In order to collect data there are several types of probability sampling methods and non-probability sampling methods we can use: Random sampling. Stratified sampling. Systematic sampling. Non random sampling. Capture recapture. Below is a brief summary of each sampling method. Sampling method. Description.The choice of sampling method depends on your research question, your population, and your resources. Generally, stratified sampling is preferred over simple random sampling when you want to
Stratified Random Sampling is a probability sampling method found in market research software that uses a two-step process to select the sample group. The population is first divided into homogeneous subpopulations, or stratas, that are mutually exclusive and collectively exhaustive. This means that every element in the population must be
In an earlier post, we saw the definition, advantages and drawback of simple random sampling. Today, we’re going to take a look at stratified sampling. This method, which is a form of random sampling, consists of dividing the entire population being studied into different subgroups or discrete strata (the plural form of the word), so that an. 41 488 406 144 318 320 364 247
