Different Types of Facebook Page Posts

Different Types of Facebook Page Posts Social media marketing is consistently growing as more consumers and businesses become involved in social media sites, and various studies have confirmed the utility of social media sites such as Facebook in building brand image and equity for businesses owners (Kim, Sung, Lee, Choi, & Sung, 2016). However, the growing number of information available on the Internet also means users are overloaded with content and need to be selective of where they direct their attention. For Facebook page owners, that means their posts will be less likely to appear in the News Feeds of ...

Abstract

One of the most prevalent addictions in our society that has far-reaching social, economic and psychological ramifications is alcoholism. At least 16.3 million Americans who are above 18 years have Alcohol Use Disorder as at 2014. However, not everyone who consumes or excessively consumes alcohol ends up with alcohol use disorder. This study speculates that persons with alcohol addiction have an inherently addictive personality and goes ahead to propose a study to investigate it. Using a random sample, a two group-study will be implemented. Personality test will be used to collect information on addictive personality. A t-test for two-groups ...

Abstract

There are different research designs that we have. Different people prefer to use the different designs for different reasons. There are threats to validity for each of the designs. There are factors that can affect the research design that an individual or a group of people carrying out the research will prefer to use:

A researcher must first find out the best research design for the particular type of research they are undertaking. Different research works work different with the research designs. The individual will have to look at the available designs and see the advantages and disadvantages of ...

Statistics in Medicine is one of the tools for analyzing experimental data and clinical observations, as well as the language with which to communicate the mathematical results. However, this is not the only task of statistics in medicine. Mathematical apparatus is widely used for diagnostic purposes, solving classification problems and finding new patterns for the formulation of new scientific hypotheses. Using statistical programs requires knowledge of basic methods and statistical analysis phases: their sequence, necessity and sufficiency. The proposed statement of the main emphasis is not on a detailed understanding of the formulas that make up the statistical methods, and ...

Generalizability

Husserl distinguishes procedure of generalization and specialization of procedures of formalization and deformalization. Generalization is the transition from the spirit to higher on the tree of generic entities and formalization - a "meaningful generalization in a purely formal logic." For example, the transition from "red" to "sensory quality" is a generalization, and the transition from "red" to "adjective" or "chalk" to "beings" or "existing" is a formalization. Similarly, deformalization is filling the empty logical form something meaningful and specialization - descent of the tree of generic. Examples of both we find in mathematics. Example of formalization: the transition from an intuitive understanding ...

Sampling Techniques

Environmental pollution is a well recognized risk factor for numerous respiratory diseases like asthma and chronic obstructive pulmonary disease (COPD) (Chauhan & Johnstone, 2003). Clinical and epidemiological studies on the link between environmental pollution and respiratory diseases are plagued by diverse and complex methodological issues (Barquera, Rico-Méndez, & Tovar, 2002). This paper will discuss the sample and sampling techniques appropriate for studying the association between respiratory diseases and environmental pollution. A random sample would be useful in examining the issue of the association between respiratory diseases and environmental pollution. However, due to difficulties in obtaining a random sample from the population ...

- Convenience sampling: it’s a non-probability technique where the subjects are chosen because of their proximity or convenient accessibility to the researcher. A good example when the researcher is short for time or resources. He would conveniently choose subjects easily accessible to save on transport cost (Levy & Stanley 25). - Cluster sampling: it is a technique where the whole population is divided into clusters and a random sample from these clusters is selected. This technique would be appropriate when the random sample is scattered so widely that surveying the subjects would be very expensive (Levy & Stanley 21). - Systematic ...

1. Is the availability of sex chat group and other sexual material on the internet psychologically healthy or damaging? Comer (2011) portrays the internet as awash in sexual material that is virtually unavoidable. This material once exposed to the children is harmful. Pornographic material on the internet is the major cause of social problems such as rape and child abuse. According to Comer (2011), sex crimes correlates with the exposure or pornographic material on the internet. Sex offenders such as the pedophiles consume much sexual material. The people that are predisposed to exploit others sexually seek pornographic pleasure. ...

Sara chose Case B – Grover’s Corner Department of Transportation, which tasked Larry, a research and program evaluation specialist, to come up with an assessment of customer satisfaction regarding the improvement the department did in terms of individual stations. Contrary to Sara’s answer (Simple Random Sample Design), I think that Larry used a non-probability sampling method with his use of a convenience sample and not a simple random sample design that utilizes a probability sample. This is because he made use of a readily available list of monthly pass users. In addition, by not going for the whole population of commuters, he left ...

Discussion questions

Metric system has only seven basic units, while the US system has more than 300 basic units; thus, it is simpler. In addition, units in metric systems are multiples of 10, therefore, calculations is easier than in US system. Metric systems are universally applied, except in USA. Perimeter is measured by distance round a figure whose SI units are meters; therefore, the perimeter is given in units of length. However, area is a derived quantity and its magnitude is obtained by multiplication of two units of length. Therefore, its units are given by the product of the units. Theoretical ...

Quantitative Research methods in statistics

The paper focuses on analyzing the use of research methods in Okello’s article “learning and Teaching college algebra at University level: Challenges and opportunities- A case study of USIU”, published in Journal of Language, Technology &entrepreneurship in Africa. Application of quantitative and qualitative methods in research (experimental and non experimental) studies is crucial for obtaining valid and reliable information. Quantitative methods or techniques lie within the interval estimation and hypothesis testing categories (Nadezhda , 2010). In interval estimation, statistics are used to estimate the interval for which the true parameter of a population lies from a representative sample. On the other ...

Question 1

(a). What is meant by the term random sample?

A sample is an item chosen from the total population, which is being studied. Therefore, a random sample is the number chosen, and it involves components that are unpredictable. This is selection of a few items to represent the entire population. The sample chosen does not represent the population from which it was drawn. This was an estimate done through survey and information from franchisors, which Tom estimated that it would be about 77000 customers in the first year according to his analysis (Dayananda, et. al. 56).
