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 ...

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.

The results obtained by the authors so far on controlled sampling with equal probabilities and without replacement have been consolidated in this paper in an integrated fashion. Utilizing these ...

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 ...

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

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, 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 ...

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.
