Sampling and Sample Size Calculation - BDCT

The usual method of obtaining random numbers is to use computer packages such as SPSS. Tables of random numbers may also be found in the appendices of most statistical textbooks. Simple random sampling, although technically valid, is a very laborious way of carrying out sampling. A simpler and quicker way is to use systematic sampling.

Basic tail and concentration bounds - Department of Statistics

Note that this is a simple form of concentration inequality, guaranteeing that X is 15 close to its mean µwhenever its variance is small. Chebyshev’s inequality follows by 16 applying Markov’s inequality to the non-negative random variable Y = (X−E[X])2. 17 Both Markov’s and Chebyshev’s inequality are sharp, meaning that they cannot ...
