Learn about the different types of ecological sampling in this bite-sized video lesson. See examples of this crucial research method, then take a quiz.
sampling bias Bayes Introduction There has been increasing interest in using electronic health record (EHR) data as part of public health surveillance efforts [1]. In an interview conducted among local health departments, Comer et al [2] reported 23 such uses, including incidence or prevalence of...
Explain the role of inferential statistics in research design and hypothesis testing. Explain the meaning of the term statistics. Compare the different types of random sampling methods. Describe an example in which stratified sampling and cluster sampling should be...
They also allow a flexible method of modeling within-cluster correlation. Subjects within the same cluster can be correlated as a result of a shared random intercept, or through a shared random slope on age (for example), or both. The general specification of G also provides additional ...
officinale in different months. In addition, the DMC of D. officinale in different months was predicted by ATR-FTIR. The results of the study can provide new methods and ideas for future research on the optimal harvesting period of D. officinale and related medicinal and food plants, and can...

there is an emphasis on the need to increase learner-centredness and develop learners’ key competences in the context of lifelong learning to ensure better compliance with employers’ demands and reduce drop-out rates in VET (Estonian Ministry of Education and Research,2009; The Estonian Lifelong ...
The isolation of graphene in 2004 can be regarded as a milestone in materials science that initiated the research field of atomically thin 2D materials1. Compared to their 3D counterparts, 2D materials have a higher surface-to-volume ratio, making them ideal candidates for catalysts and sensors2...
