In this paper we derive the exact covariance of some sample moments for 'simple random sampling with replacement' (SRSWR) of a finite population. An application of the results is given for estimating ...

As an estimator of the population mean, the sample mean based only on the distinct units possesses a remarkable invariance property. Under three forms of simple random sampling, viz. simple random ...

Consider a population of 70 individuals, for which you wish to estimate the mean annual income, μ. Assume that you have decided to use the following estimation procedure to make your estimate: simple ...

In simple random sampling, each unit has an equal probability of selection, and sampling is without replacement. Without-replacement sampling means that a unit cannot be selected more than once.

In simple random sampling, units are selected without replacement, which means that a unit cannot be selected more than once. Both systematic and sequential equal probability sampling are also without ...

A simple random sample is a subset of a statistical population where each member of the population is equally likely to be chosen.

Simple random sampling – In this sampling method, each item in the population has an equal probability of getting selected in the sample. First, you must assign a unique identifier to each item.
