guns. Describe why this is a cluster sample. What is the psu? The ssu? Is it a one-stage or two-stage cluster sample? How would you estimate the percentage of households with guns‚ and the standard error of your estimate? What is the sampling population for this study? Do you think this sampling procedure results in a representative sample of households with children? Why‚ or why not? Solution: This is a cluster sample because all the elements within the clusters are selected. (Example: All

Aim * To educate students on what instruments they should use for sampling of water sample. * To expose the students the proper technique to measure the water. * To give the students experience with sampling of water sample. Introduction Pollution can be defined as a harm to the environment which can cause a lot of bad consequences to human health‚ living resources and ecological. Thus‚ pollutants can be gain from many sources and can take many forms. The pollutants can contaminate

Purposive sampling Purposive sampling‚ also known as judgmental‚ selective or subjective sampling‚ is a type of non-probability sampling technique. Non-probability sampling focuses on sampling techniques where the units that are investigated are based on the judgement of the researcher. Purposive sampling explained Purposive sampling represents a group of different non-probability sampling techniques. Also known as judgmental‚ selectiveor subjective sampling‚ purposive sampling relies on

What kind of sampling technique are you using (simple random‚ stratiﬁed‚ systematic‚ cluster‚ multistage‚ convenience)? Answer: For all students I would use the convenience sampling. The reason I would use this method is because college students often are very busy between school and work there is not very much room for anything else. So I would

SAMPLING TECHINIQUE PROBABILITY SAMPLING Having chosen a suitable sampling frame and established the actual sample size required‚ you need to select the most appropriate sampling technique to obtain a representative sample. The basic principle of probability sampling is that elements are randomly selected in a population. This ensures that bias is avoided in the identification of the elements. It is an efficient method of selecting elements which may have varied characteristics‚ as the process

Sampling methodologies Sampling It may be defined as a process of selecting units that may be people‚ organizations etc‚ from a larger whole i.e. from a population of interest‚ so that by studying the sample we may come up with general characteristics of the entire population under consideration. Types of sampling methods: Probability sampling Probability sampling is a type of sampling that includes random selection. And in order to achieve random selection‚ it must be

Sampling and Sampling Methods There are many research questions we would like to answer that involve populations that are too large to consider learning about every member of the population. How have wages of European workers changed over the past ten years? Questions such as this are important in understanding the world around us‚ yet it would be impractical‚ if not impossible‚ to measure the wages of all European workers. Generally‚ in answering such questions‚ social scientists examine a fraction
Premium Sampling Sampling techniques
There are many ways to select a random sample. Four of them are discussed below: Simple Random Sampling: In this sampling technique‚ each sample of the same size has the same probability of being selected. Such a sample is called a simple random sample. One way to select a simple random sample is by a lottery or drawing. For example‚ if we need to select 5 students from a class of 50‚ we write each of the 50 names on a separate piece of paper. Then‚ we place all 50 names in a hat and mix them thoroughly
