Normal Distribution - Essay ExampleFrom the results obtained a conclusion is haggard as to whether typical diffusion curves are suitable for analysing any system behavior.A universal diffusion curve is one of the most commonly utilize statistical tools. Many natural phenomena conform to a normal diffusion with most elements clustering at the centre and a few extremes on the remedy and the left. Normal distribution is also called Gaussian distribution or the campana shaped distribution as the resulting graph has a ships 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 information of system behavior, the random variable is used to describe the unpredictable outcome. When a survey or an taste is carried out, the data collected is also referred to as a variable. Variables can be classified as decided random variable or continuous random variable. Discrete random variable consists of a driven of data that takes discrete values that is, the values can be counted. These values are finite and denumerable. regular random variables are on the former(a) 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 undischarged use is derived from the fact that its a simple model that represents complex data (Feller, 1968).LITERATURE REVIEWAbraham 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 withdraw 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 attached collected data to normal distribution and determine its practicability and adaptability in the evaluation of a granted system behavior. The researcher will collect data and from this data, draw the normal distribution curve and tests it boilersuit suitability as a statistical tool. OBJECTIVESThe main objective of this study is to determine whether the normal distribution curve is the most suitable method of analysing a syste m behavior. In this case, the number of emails sent per day. The peculiar(prenominal) objectives areCollect the data.Calculate the mean,
