Random Sampling

Simple random sampling is the most widely used statistical tool in large populations, where each unit or sample of a population is considered during analysis. Random sampling is considered to be ‘God standard’ of all the types of sampling techniques available. The major reason of random sampling being important is that it reduces any possible human bias. This includes bias created in selection of a sample or case to be included in the study sample. This technique represents the entire population, avoiding any possible missing data. The overall technique is simple, accurate and should be used for smaller population size. Generalizability ...

Justifications, Problems, and Solutions

The broad goal of conservation biology is, according to experts from the American Museum of Natural History, is “to conserve global biodiversity” (Calcagonotto, Egan, and Lehn 2001). Small population conservation biology is a facet of conservation biology that deals with the more specific issue of trying to preserve endangered species that have extremely low populations, and the efforts to conserve these species can be very expensive. The question of whether or not this type of conservation biology is ethically justifiable is one that can be explored by examining the approach of small population conservation biology, examining a test case from the ...

Questions

1) Construction of the pyramid for the year 2006 and 2036 respectively
2006
5 years Age Group

2036
5 Years Age Group

2) Median Age for the year 2006 for both males and females

The median ages for the 5 year groups in the year 2006

For Males and Females:

The sum of the ages is an even number, Hence the median will be sum of the two middle numbers then you divide by 2
= 45+46
2
= 92/2
=45.5
= 46 is the median age for single years for the year 2006 for both males and females which is the same with the ...

Literature review

Kaasa, S. (2015). Is Cancer Pain Control Improved by a Simple WHO Pain Analgesic Ladder Approach Combined With Tumor-Directed Treatment?.Journal of Clinical Oncology, JCO647537.

Article summary

This article takes into consideration the role that the WHO analgesic ladder plays in addressing cancer pain in palliative care patients. The authors identify that cancer pain occurs in 90% of cancer patients but only half them are under proper pain management. To this effect, therefore, there is the need for applying opioids under the WHO ladder guidelines as a way of addressing cancer pain in oncology care patients.

This is a narrative qualitative research ...

HCA 302. Health Care Organization

Introduction
Health care systems are essential in providing security to nation-states world-over, which goes beyond health issues; entire economies depend on such vital system for security. One only has to imagine the devastation of a population by an infectious disease such as HIV/AIDS. Despite having some similarities, health systems vary from one country to the other. Notably, nations design as well as develop their health systems in line with their needs as well as the available resources. The United States and Canada share a border, and thus there is a natural inclination to compare the two health care regimes. ...

1. DNA in forensic science: DNA contains the genetic code of a person. The genetic information stored in the DNA, is coded in the form of nucleotide sequence. The nucleotide sequence is formed by four fundamental nucleotides: A, T, G, C nucleotide, that formed a polymer in a set order. A typical human DNA, has 3 billion nucleotide bases. The DNA sequence is 99.8% identical in all human beings and is only 0.2% dissimilar. This dissimilarity is the basis for identification of the suspects in forensic medicine. No two human beings can have a DNA that is 100% identical. ...

Human population has experienced explosive growth over the recent decades. Population dynamics is a multifaceted aspect that encompasses not only population size, growth and density, but also the peculiarities of urbanization and migration taking into account such variables as age and sex (de Sherbinin et al., 2007). Lam, (2011) points out that demographic change is closely related to the three aspects, namely urbanization, fertility decline, and investment in children. “The growth of the world population goes hand in hand with global urbanisation: while around the year 1950 less than 30% of people lived in the cities, this proportion has ...

Argument for population in the world

With high population and complementing technology, there will be efficiency in the economic system of a country. Therefore, a high population, coupled with this efficiency will lead to high productivity in an economy. Such an economy will record high growth rates.
The other factor is that a high population provides a large market. Countries with a high population have a large and stable market for their products. As a result, companies operating in such regions enjoy high sales and hence high tax remittance for the government. Consumers in such countries obtain commodities at relatively low prices due to mass production.
Another argument is that a ...

Marketing entails positioning products and services in the market through different strategies that focus on the marketing elements; mainly the product, pricing, promotion and place elements. However, the elements are determined by several factors which are in-turn dependent on the economic, social, political, cultural, legal and technological factors as well as the development stage of an economy. On the other hand, a less developed country is marked by persistent low economic growth as well as relatively low social welfare and life standards compared to the developed countries that have high economic growth, high life standards as well as significant aggregate ...

Selecting the right study sample is influenced by the intended population size and purpose of the study. It is also essential to understand the sampling error/precision to determine the range where the true value should be drawn from and the estimated risk level also known as the confidence level and the variability involved (Israel, 2013). In selecting the sample size, the researcher can use several basic methods which involves using the entire population as the research sample in case the study population is small, use of sample sizes that have been used in similar studies or use of already ...

Introduction

Pulmonary TB is a disease caused by a bacterium called Mycobacterium tuberculosis that attacks the lungs in human beings (WHO). The major symptoms include: coughing; chest pains, shortness of breath; appetite loss; loss of weight; night sweats; and fatigue. If untreated the disease is fatal and leads to death. In 2007, alone there was 13.7 million cases infection and 9.3 million new cases globally (WHO, 2008). In 1993, WHO (World Health Organization) declared TB a global emergency. In addition, the organization predicts that the disease will kill over 35 million people over the next twenty years if strategies are not set to ...
