An essay on fundamentals of statistics will entail the base concepts of statistics which will include the mean, median and mode. Some of these types of essays will have elements of central tendencies such as standard deviation and measures of variability. An essay on fundamentals of statistics will define the mean as the arithmetic average of total variables in a data set. In an essay of fundamental of statistics the mode is defined as the variable that appears most in a given data set while the median is defined as the central value in ascending format. The most important aspect of a statistics essay is that there must be a relative frequency of an event so that one is able to calculate the measures of variability.
There are general concepts which one must consider when coming up with a set of statistical data for an essay of fundamental statistics. A statistics essay must consider the factor of precision and accuracy where one must be able to consider defining the detection limit and sensitivity. These aspects generally are put in place to check the credibility and accuracy of the data selected since most of the data collected in the field is considered raw. Such kinds of application are mainly done on research findings, especially research that is related to health issues. In any data processing, the scaling of data is very important since it gives the approximate area of data collected and is easy to estimate. In the scaling of data, it is quite easy to find the missing values of the raw data since there is consistency which is reflected in the approximation of data. Variable selection of data is done during the visualization stages.
Fundamentals of Statistics essay example
Statistics is beyond doubt one of the most important disciplines of our time much like medicine in medieval Europe and law in ancient Greece. This is because statistics is so commonly used in today’s society to give us an idea of the current state of our environment. This current state is in contemporary society based upon numbers and these numbers are generated by and come in the form of statistics.
It is also important to recognize that like all great disciplines like law, philosophy, engineering, economics and medicine statistics is also made up of certain fundamentals that form are at its core(Timothy 2001). These fundamentals form the basic building blocks of statistics much as cells from the basic building blocks of all living organisms. These fundamentals are a common phenomenon and known to almost everyone who at one time or another has undertaken any given form of research be it simple window shopping to compare and contrast prices or an extensive post graduate thesis.
These fundamentals can be categorized into a few distinct parts. Absence of any of these fundamentals would greatly jeopardize the consistency and unbiased nature of any statistical undertaking. The first fundamental aspect is accuracy, precision and variation which must be present in all statistical work and is ensured by having the correct methodology and sampling techniques in conjunction with expert researchers.
The second fundamental of statistics is the sample frequency distribution. It forms the entire backbone of the research since it will be used to test the generated hypotheses and make inferences about the population(Singh 2010). The third fundamental aspect is the population or sample. This must be present since statistics cannot be taken from abstract and nonexistent entities. Other fundamentals include basic knowledge of statistical tools that represent data such as histograms, the normal curve etc.
