## Extract of sample "History of Statistics"

17 October 2006 Statistics Generally speaking, statistics is commonly defined as "the mathematical science pertaining to the collection, analysis, interpretation, and presentation of data" (Statistics 1). However, Benitez offers a much more precise definition of statistics which delineates it from the science of mathematics. According to him, statistics can be specifically and accurately defined as "the science that looks at the study of generic phenomena, normally complex and framed in a variable universe by means of reduction models of information and validation analysis of the results in representative terms" (Benitez 1). He further elaborated that statistics can be applied to numeric, alphabetical, and even symbolic data.
Statistics has been traditionally regarded as the "science of the state" because its original designation and application is in the analysis of the data about the state. Statistics is primarily used to refer to the collection and classification of data for governmental and administrative bodies in the early 19th century. The 20th century saw a substantial advancement in statistics as this science is not only employed to gather demographic data but has also become an instrumental tool in the analysis of public health concerns, economic, and social matters (Statistics 3-5).
With these developments, the task of statistician has branched out from the collection and analysis of the governmental data to encompass other sectors like business and industry, health and medicine, learning, research, social scientists and natural resources (Careers in Statistics 1-20). Statistics is important to all these fields as the often predict and test the validity of various hypothesis. The main task of the statistician in these diverse fields is to carry out the statistical processes-data collection, analysis, presentation, interpretation of results and elaboration of methods. Statisticians must also determine the validity of the data they gather. With these broad responsibilities, statisticians can be involved in administering surveys, developing a statistical model, and presentation to data users. However, they deal with different topics according to their field. For example, a statistician in scientific researches may investigate the effectiveness of new treatments on patients. On the other hand, statisticians on businesses work on the forecast of the demand for products and services.
However, the use of statistics is not only limited to statisticians. All of us use statistical concepts often unknowingly though they may not be as complex as the ones employed by the professional statisticians. As a student, finding our average grade for the semester necessitates the calculation of the mean. Also, all of us often generate forecasts for our monthly expenses using our previous disbursements.
Different variables in statistics are often used to asses the economic situation of our country. One of the most commonly discussed in the newspapers is gross domestic product or GDP. These forecasts are generated through the use of time series regression which utilizes the recorded past values of GDP. GDP forecast is often necessary for investors, businessmen and other economic planners.

...?Because there are 50 numbers, we can divide these numbers into groups of 10 (5 groups). Next we subtract the lowest number from the highest number (76 — 16 = 60). After this, we will divide the difference by the number of groups that we came up with (60 / 5 = 12). Once we get the class width (12), we add it to the lowest number in order to get the lowest class limit (16 + 12 = 28). If we keep on repeating this step, we can determine all the appropriate class limits (28 + 12 = 40, 40 + 12 = 52, 52 + 12 = 64, and 64 + 12 = 76). Because these are the maximum limits, we have to subtract 1 from each class limit (16 + 12 — 1 = 27, 28 + 12 — 1 = 39, 40 + 12 — 1 = 51, 52 + 12 — 1 = 63). Now that we have worked this out, we can create... there are 50 ...

There are a number of evidences which show that the concentration of atmospheric carbon dioxide has been steady increasing globally.

### The Discourses of Psychology and History

Psychology as a field of discourse relies heavily on empirical evidence; being a social science, this empirical evidence is still subject to much subjective analysis. This is not to say that there is no room in chemistry for any sort of subjective analysis, but there is not nearly as much leeway as there would be in social science like psychology. This is the reason why there is such a contrasting difference in the way that theories are phrased in hard sciences and social sciences.

Concerning written assignments in psychology courses, there is a definite, approved approach that must be followed. Generally speaking, psychology paper assignments are not supposed to contain quotations from other papers; the findings of ano...

### Cultural History Versus Political History: The Varying Methods of the Two Fathers of History

Even though they have these similarities and have both been bestowed with the same title, these two historians drastically differed in their approaches.

Herodotus had another title bestowed upon him; he was also called the “Father of Lies.” Much of what is known of him has been gathered from his own writings as few other sources are available from his actual life. It should also be noted that the veracity of this information is in question as Herodotus was known to invent much in his own work, and it was sometimes the practice in Ancient Greece to attribute events from the life of one person to another; for instance, it has been questioned if the accounts of Herodotus’ exile are only due to the fact th...

### Art History: Catalan Chapel and Classical Greek and Republican Roman Sculpture

Characteristic of a fresco, the piece is made with secco placed on plaster and wood. Originally part of the church structure, the entire fresco was removed and went through several sales before being acquired by the Boston museum. Part of its ability to astound is its massive size. It measures approximately 21 feet at its tallest point and more than 12 feet across. Because it was originally intended to decorate the interior of a small circular area of the church, it is not flat either, but rather has a concave presentation forcing the museum to dedicate approximately 9 feet of space in depth to accommodate it. As a result of its origins and intent, as well as age and travels, the piece has sustained heavy damage, particularly alon...

The same is true of any writer. One is trying to get into a unique writing style, often without deliberate inclinations-- the style emerges of its own, -- but sometimes, the narrative voice as a writing technique is consciously employed by the writer. To start with, it is necessary for the writer to select which POV (point of view) to use.

The author’s persona of a fictional narrative can contribute to or mar the success of the story. Much depends on the plot of the story and how the author wishes to develop it. What is the emotional content of the story as a whole and how the individual emotional levels contribute to the total success of the story? There should not be any artificiality about the development of th...
