Sampling techniques

Sampling Strategy and Sample Size for a Quantitative Research Plan Introduction When a researcher is constructing a sampling method, the questions about the population where the sample will come from and the size of the sample to be used come into play for the purpose of seeking statistical validity (Frankfort-Nachmias & Nachmias, 2008). Parahoo (2014) explains that, in order for sampling method or strategy to be considered credible, defining the population to be sampled, type of sampling,…

are limited in number possibly due to the nature of the researched issue or phenomenon. Similarly, a non probabilistic sampling orientation was adopted because the goal of the study is not to generalise to the population, but to obtain insights about a phenomenon by selecting individuals that will increase the understanding of that underlying phenomenon through a purposive sampling method (Onwuegbuzie and Collins, 2007, P.…

Public Opinion Surveys Public opinion surveys, or polls, are exactly what they sound like; a survey that asks the public their opinion on a topic. Polls are a form of inductive generalization because they gather information from a number of people and generalize their findings to cover the rest of the population. With that said, polls are used specifically for this purpose, which we can see in the media every day. One of the largest problems with the polls we see every day is that the details…

It was decided to use a non-probability sampling method. Even though this method is less valid, due to not having access to a sampling frame the probability sampling method could not be done and therefore, the only option was a non-probability sampling method. The non-probability method used was quota sampling; this is where the population is divided into subgroups by their characteristics, traits or a focused fact. Following this quota sampling; the questionnaires were handed out to fifteen…

A Quantitative Research Design Critique The research problem that I have selected in Unit 1 is pressure ulcers. There have been research and studies conducted in order to shed light on this problem. There are research studies that aim to prevent pressure ulcers from happening by implementing interventions. Aside from that, as healthcare professionals, we have to determine the validity of the study. This paper aims to review the research conducted by Bergstrom et al. (2013) in determining the…

learning with the hope that students will become lifelong learners. Motivation to learn can be a key component in this process of creating lifelong learners and individuals motivated to achieve great things. The purpose of this study is to explore the techniques of formative feedback and analyze the effect it has on student motivation in math. In a situation where teachers provide students with positive instruction based feedback studies have shown that this has a positive effect on student…

Relationship between the classroom learning environment and student goal orientation. There are many patterns that links classroom structure and the differences in the goals of a student. Performance and learning goals is one of the set models. There are students who set performances goals and are focus on striving to complete those goals. Learning goals are set to increase the common core of what they should know. Evaluating the Significance of the Problem The checklist for evaluating the…

I. Introduction 1. DEFINITION 1.1. Cyberbullying is defined as “an aggressive, intentional act carried out by a group or individual, using electronic forms of contact repeatedly and over time against a victim who cannot easily defend him or herself” (Smith et al 2008 ) 1.2. Cyberbully is the person who does cyberbullying 1.3. Netiquette means “respecting other user’s views and displaying common courtesy when posting your views to online discussion groups.” (BBC, 2012) 1. INTRODUCTION Advanced…

Non parametric tests It is a hypothesis test which does not need population distribution. For instance there are numerous hypothesis tests which depend upon assumptions that population must be normally distributed along with the parameters. Main advantages of non- parametric tests are that they do not rely on assumptions, so they can be easily used where population is non-normal. One thing to be kept in mind, that these tests may have few assumptions related to the data. They might not be…

40 or higher on the scale is required to required to meet the SED criteria. The sampling method used was non-probability sampling, in which every element has an unknown and usually different chance of selection. Non-probability sampling is not representative of the population, no generalizations can be made, only speculations that what hold true for the sample also does for the population. Non-probability sampling was appropriate for the research question because they were not randomly…
