May 26, 2017 · What is Scanning Electron Microscopy (SEM) A typical SEM instrument, showing the electron column, sample chamber, EDS detector, electronics console, and visual display monitors. The scanning electron microscope (SEM) uses a focused beam of high-energy electrons to generate a variety of signals at the surface of solid specimens.

Mar 10, 2015 · The SEM quantifies how far your estimate of the mean is likely to be from the true population mean. So smaller means more precise / accurate. In that sense, SEM=1.5 indicates that your sample mean is a more accurate estimate of the population mean than if SEM was 3.5. Share. Improve this answer.

Introduction. Path Analysis is a causal modeling approach to exploring the correlations within a defined network.The method is also known as Structural Equation Modeling (SEM), Covariance Structural Equation Modeling (CSEM), Analysis of Covariance Structures, or Covariance Structure Analysis.
