Cluster Sampling Vs Stratified Sampling

cluster sampling vs stratified sampling special research report Photo by
Along with other methods of sampling, cluster sampling is preferred by experienced and professional statistical data analyzers. Cluster sampling advantages and some other information on sampling is illustrated in the following article. Before we try to understand the advantages of cluster sampling, let us take a look at the key definitions, which will help us in understanding the concept better. Key Definitions Sampling : It is a technique in which certain members of a population group are selected so that they can act as representatives for the entire population. Sampling Unit : The subject on which information is to be ...
Researchers rarely survey the entire population for two reasons (Adèr, Mellenbergh, & Hand, 2008): the cost is too high, and the population is dynamic in that the individuals making up the population may change over time. The three main advantages of sampling are that the cost is lower, data collection is faster, and since the data set is smaller it is possible to ensure homogeneity and to improve the accuracy and quality of the data. Each observation measures one or more properties (such as weight, location, color) of observable bodies distinguished as independent objects or individuals. In survey sampling , survey weights can ...
Research Methodology
Action research examines events. It is qualitative in nature; it is also teacher-generated. Action research projects are often longitudinal i.e. carried out over a period of time. The strength of this research is that it allows teachers to diagnose, investigate and resolve classroom problems. This type of research has the specific aim of addressing specific situations / problems in the classroom.. it is based on participant observations, open-ended. Experimental research examines outcomes, it is quantitative. It attempts to quantify outcomes resulting from treatments. It examines the behaviour of a representative cross-section ... market research, surveys and trends

RESEARCH FORUM--The Research Sample, Part I: Sampling - Journal of ...
The cost of studying an entire population to answer a specific question is usually prohibitive in terms of time, money and resources. Therefore, a subset of subjects representative of a given population must be selected; this is called sampling. The concepts involved in selecting subjects to represent the larger population are presented. Sampling errors and associated determining factors are reviewed. Definitions of the research populations, including target and accessible groups, are given. The inclusion and exclusion criteria required to refine the accessible population to a researchable subgroup are ... industry trends, business articles and survey research

  The impact of different benefit packages of Medical Financial Assistance Scheme on health service utilization of poor population in Rural China Since 2003 and 2005, National Pilot Medical Financial Assistance Scheme (MFA) has been implemented in rural and urban areas of China to improve the poorest families'accessibility to health services. Local governments of the pilot areas formulated various benefit packages. Comparative evaluation research on the effect of different benefit packages is urgently needed to provide evidence for improving policy-making of MFA. This study was based on a MFA pilot project, which ... market trends, news research and surveys resources
The School the largest 'workplace'
Ergonomics is the scientific study of the people and their work. It helps in improving human performance and finds solutions to health and safety problems. The school is the largest workplace of all. Children are the “workers” there. Matched ergonomic arrangement at the place of work is essential for better human performance. Musculoskeletal pain, general tiredness, lateral deviation of the spine and poor educational performance have been identified as key negative effects due to mismatched ergonomics in the classroom. Feasible solutions are available to mitigate ergonomic risks. Many developed countries have ... market trends, news research and surveys resources

Cluster sampling vs stratified sampling? - Yahoo! Answers
The main difference between cluster sampling and stratified sampling is that in cluster sampling the cluster is treated as the sampling unit so analysis is done on a population of clusters (at least in the first stage). In stratified sampling, the analysis is done on elements within strata. In stratified sampling, a random sample is drawn from each of the strata, whereas in cluster sampling only the selected clusters are studied. The main objective of cluster sampling is to reduce costs by increasing sampling efficiency. This contrasts with stratified sampling where the main objective is to increase precision.
