Research On Population And Sampling - 1121 Words

Population and Sampling Introduction Research may seem difficult outsiders because by looking at all the work done to satisfy your research. What people often misunderstand is that research can be simplified if you know exactly what you are looking for. When conducting any form of research, you must be specific with your work. Important aspects of any research project consist of figuring out what your population and sample will be. Some often assume that a researcher’s population and sampling are one in the same but that is incorrect. Knowing the difference between the two can make your research much easier and effective. Population According to Neuman (2011), â€Å"Population is the abstract idea of a large group of many cases from which†¦show more content†¦Sampling Scientists as a rule can t mention direct objective facts of each person in the populace they are contemplating. Rather, they gather information from a subset of people, an example and utilize those perceptions to make derivations about the whole populace. Preferably, the example relates to the bigger populace on the characteristic(s) of interest. All things considered, the specialist s decisions from the specimen are most likely appropriate to the whole population. For my research I will be using only one type of sample data: Quota Sampling is a nonrandom sample in which the researchers first identify general categories into which cases or people will be placed and then selects cases to reach a predetermined number in each specific category. According to (Newman, 2011) Quota Sampling is relatively easy considering it uses three popular c ategories: gender, race, and sex. In quota sampling, the researcher aims to represent the major characteristics of the population by sampling a proportional amount of each. Another form of sampling is Random Sampling, which uses numbers and tables so that each sampling element of a population has an equal probability of being selected into the sample. Most of random sampling techniques represent the entire population when searching for data and results. The simple random sample is a subset of a statistical population in which each member of the subset has anShow MoreRelatedQuestions On Non Probability Sampling1039 Words   |  5 Pagesnon-probability sampling is and the different types such as snowball sampling, quota sampling, convenience sampling and purposive sampling. In addition, the pros and cons of non-probability will be discussed such as the correct sample size, determining the desired precision, and managing the variation in the population to name a few examples. Furtherm ore, this journal will discuss why a researcher might want to use non-probability sampling over other methods such as cluster sampling or systematic randomRead MoreAdvantages Of Simple Sampling And Accuracy Of Representation801 Words   |  4 PagesAdvantages of simple sampling: a. Representative and Freedom from human bias b. Ease of sampling and accuracy of representation (Andrews, 1999-2015). Disadvantages of simple sampling: a. It is expensive and time consuming. b. Sample selection bias may occur (Horton, 2015). Systematic random sampling: can be described as a most commonly used method in which after a number has been allocated to an individual in the population frame, the first person is selected using a random number table or out ofRead MoreAnalyzing Different Approaches Of Sampling885 Words   |  4 Pagesdifferent approaches of sampling. Sampling refers to the statistical process of selecting a portion of the population that is being studied to represent the attributes of the entire populations ( Polit Beck, 2014). The different strategies of sampling includes: 1. Probability sampling is typically used in quantitative research studies (Polit Beck, 2014). It involves a specific analytical process that requires the random selection of attributes from a population that is being studied, whichRead MoreSampling Methods Essay1025 Words   |  5 Pages Sampling Methods A great deal of sociological research makes use of sampling. This is a technique aiming to reduce the number of respondents in a piece of research, whilst retaining - as accurately as possible - the characteristics of the whole group. The purpose of taking a sample is to investigate features of the population in greater detail than could be done if the total population was used, and to draw inferences about this population. In addition, at theRead MoreResearch Study On Data Analysis Essay1213 Words   |  5 Pages CHAPTER 3 3.

Section 3.2 outlines the sampling techniques that can be used to choose representative respondents to the population under study. It will give a brief explanation on sampling and also explanation on various sampling techniques. Section 3.3 focuses on the data collection methods. It will give a brief explanation of various data collection methods.

Also, Non-probability sampling is a sampling technique where the samples are gathered in a process that does not give all the individuals in the population equal chances of being selected. In contrast with probability sampling, non-probability sample is not a product
