ed. Beyondthe contribution of our colleagues, and in all cases, we do not consider ourselves to be the lone authors of these exercises:they actually form part of a common heritagefrom ENSAI that has been enriched and improved due to questions from students and the work of all the demonstrators of the sampling course at ENSAI.doi:...
Radial sampling ofk-space data, one of the earliest methods for image reconstruction, was largely supplanted in the 1980's by the "spin-warp" technique that employed rectilinear (Cartesian) data acquisition. To this day, Cartesian methods remain dominant, but radial (and spiral) approaches are ...

Sampling and Sampling Methods There are many research questions we would like to answer that involve populations that are too large to consider learning...
Limitations of Sampling Sampling demands a thorough knowledge of sampling methods. Small sample is not always good. A Complicated sampling may require more labour. Not possible to ensure representativeness. Sampling method fall into two categories: Probability Sampling: Every individual in the population...
This method is the most straightforward of all the probability sampling methods, since it only involves a single random selection and requires little advance knowledge about the population. Because it uses randomization, any research performed on this sample should have high internal and external validi...
Frequently asked questions (FAQs) about simple random sampling What if I’m working with a large population? Where sample sizes and the participant population are large, manual methods for selection aren’t feasible with the available time and resources. This is where computer-aided methods are ...
3.1.5 Computer Intensive Methods Monte Carlo or simulation methods can be very useful approaches to evaluating the properties of estimators, and they are widely used. In particular, they can be used to evaluate bias in estimators, either due to small samples or to the failure of assumptions. ...
