Normal Distribution - Essay Example From the results obtained a conclusion is drawn as to whether normal distribution curves are suitable for analysing any system behavior. A normal distribution curve is one of the most commonly used statistical tools. Many natural phenomena conform to a normal distribution with most elements clustering at the centre and a few extremes on the right and the left. Normal distribution is also called Gaussian distribution or the bell shaped distribution as the resulting graph has a bell shaped nature. Data tends to cluster near the mean or the average. The bell shaped curve is a probability density function with a peak at the mean. During the study of system behavior, the random variable is used to describe the unpredictable outcome. When a survey or an experiment is carried out, the data collected is also referred to as a variable. Variables can be classified as discrete random variable or continuous random variable. Discrete random variable consists of a set of data that takes discrete values that is, the values can be counted. These values are finite and denumerable. Continuous random variables are on the other hand are not denumerable (Cary 2008). Normal distribution has been used extensively in natural and social sciences and also in the evaluation of statistical data. It great use is derived from the fact that it's a simple model that represents complex data (Feller, 1968). LITERATURE REVIEW Abraham De Moivre introduced the normal distribution in the year 1733; this was printed in his book 'the doctrine of chances' in 1738. He used the normal distribution to evaluate large binomial distribution. The normal distribution theory was later extended by Laplace in 1812 to form the theorem of De Moivre-Laplace. Laplace used normal distribution to evaluate analytical errors during his experimental work. Gauss in 1809 used the method to analyse his astronomical work while Legendre used the method in 1805. The term bell shaped distribution function was first used by Esprit Jouffret in 1872 and later the graph was referred to as the normal distribution by Charles Pierce and Francis Galton. Normal distribution has been extensively used to study scientific and natural phenomena as well as analyse statistical data. The method is however not appropriate for the study of all phenomena, instead other distribution are preferred in some cases. The other popular distributions are the binomial and poison distribution. In light of this, the researcher seeks to subject a given collected data to normal distribution and determine its practicability and adaptability in the evaluation of a given system behavior. The researcher will collect data and from this data, draw the normal distribution curve and tests it overall suitability as a statistical tool. OBJECTIVES The main objective of this study is to determine whether the normal distribution curve is the most suitable method of analysing a system behavior. In this case, the number of emails sent per day. The specific objectives are; Collect the data. Calculate the mean,

Ethics in Auditing - Research Paper Example An auditor is a business professional with the responsibility to assess various features of an organization, individual actions or project implementation to ascertain that resources are used efficiently, which includes finances, labour, inputs and any other factor of production that may affect business efficiency as well as the authenticity of the financial accounts of the business. The auditor is expected to provide an audit report with recommendations concerning the amendment of inaccurate entries and situations that may negatively affect the organization. Auditors are expected to adhere to professional ethics and in a manner that promotes the organization’s well-being. This paper focuses on ethical standards in auditing and why those standards are important. It also highlights ethical auditing violations and how they can be avoided. Ethical Standards in Auditing McWilliams & Nahavandi (2006) highlight the code of ethics in auditing whereby ethical standards and expectations need to be adhered to with regards to the conduct of individuals and organizations in an audit process. Auditors need to be morally responsible for their actions in the process of auditing and need to understand their impact on the future of the organization. An audit report may lead to improvement of business competitiveness, but on the other hand it may also result in dire consequences such as termination of contracts, employment, fines and lawsuits. Professional ethics is therefore an important component in auditing. Public confidence is achieved through adherence to good code of ethics, which reflects effectiveness and efficiency. Ethical standards give an organization and the public the reassurance needed with regards to risk control and effectiveness (Beauchamp & Bowie, 2010). Auditors are expected to maintain integrity in their actions, which is an important indicator of trustworthiness and hence the reliability of their findings and final conclusion. According to McWilliams & Nahavandi (2006), auditors need to observe the values of independence, impartiality in their judgement, high moral standards with regards to professional demeanour as well as unconditional honesty in their activities. Conflict of interest is a vice that needs to be avoided in auditing since it may lead to biased results. Fear or favour may also influence the outcome of auditing since the auditor may avoid certain aspects that may help unveil important loopholes through which organizational efficiency is likely to be lost. Auditors need to exercise unmatched standards of even-handedness, honesty and ethical behaviour. They need to accomplish their work with uprightness, meticulousness and accountability while observing the law (Jamal, 2004). They are obligated to make disclosures stipulated by the law and in line with professional obligations. They should avoid situations that may unintentionally lead them to be party to any unlawful activity or get involved in actions that are di sreputable to the auditing profession or to a business. Howieson (2003) notes that auditors need to demonstrate respect for the work of fellow auditors whether in the same or different organization and also recognize their distinct capabilities are areas of competency. Respect for other players in the audit profession promotes good work relations and possibility of future collaborations. Objectivity is the frame of mind
