Simple random sampling (SRS) provides a natural starting point for a discussion of probability sampling methods, not because it is widely used—it is not—but because it is the simplest method and it underlies many of the more complex methods. i) Simple random sampling: in this method each element has the equal probability to be selected as a sample. It is bias free. Here an element cannot come twice as sample. ii) Stratified random sampling: In stratified random sampling the population is first divided into different homogeneous group or strata which may be based upon a single
A population of nine drug addicts is featured to explain the concepts of simple random sampling. All nine addicts have injected heroin into their veins many times during the past weeks, and have often shared needles and injection equipment with colleagues. Three of the nine addicts are now infected with the human immunodeficiency virus (H IV Chapter 4 Stratified Sampling An important objective in any estimation problem is to obtain an estimator of a population parameter which can take care of the salient features of the population. If the population is homogeneous with respect to the characteristic under study, then the method of simple random sampling will yield a
In this tutorial we will learn how to create sampling in Excel. We will explain how to create a simple random sampling in excel and periodic sample in Excel. Simple Random Sampling: Selecting random number of data from the dataset with repetition. Periodic sampling: A periodic sampling method selects every nth item from the data set. In a study where the unit of analysis is the student, the researcher must obtain a complete list of every student in the target population to achieve simple random sampling. This is rarely possible, so very few, if any, educational studies use simple random sampling. Another factor to consider is the word random.
• The reciprocal of the sampling fraction is called the Raising Factor. • A sample, in which every unit has the same probability of selection, is called a random sample. If no repetitions are allowed, it is termed as a simple random sample selected without replacement. If repetitions are permitted, the sample is selected with replacement. Disadvantages of Simple random sampling. Simple random sampling suffers from the following demerits: 1. This method carries larger errors from the same sample size than that are found in stratified sampling. 2. In simple random sampling, the selection of sample becomes impossible if the units or items are widely dispersed. 3.
