SAMPLING TECHNIQUES INTRODUCTION
... Probability sampling (a term due to Deming, [Deming]) is a sampling porcess that utilizes some form of random selection. In probability sampling, each unit is drawn with known probability, [Yamane, p3] or has a nonzero chance of being selected in the sample. [Raj, p10] Such samples are usually selec ...

Foundations for inference
... The sampling distribution represents the distribution of the point estimates based on samples of a fixed size from a certain population. It is useful to think of a particular point estimate as being drawn from such a distribution. Understanding the concept of a sampling distribution is central to un ...

The standard deviation provides an overall measurement of how much participants' scores differ from what other statistic? 4. If the differences among a set of scores are small, this indicates which of the following? A. There i ...

... When complete information is collected for all the units belonging to a population, it is defined as complete enumeration or census. In most cases, we prefer sample survey to complete enumeration due to the following factors: (a) Speed: As compared to census, a sample survey could be conducted, usua ...
