Statistics As a person stare at a wall and develops a thought process on how to figure out how he or she could solve an issue or come to an assumption is intriguing. People go through life without finding out the why behind the process and is the why the solution to the problem. Statistics is essential because it shows the actual value of someone findings and Heinrich Hartmann said that “statistics is the art of extracting information from data, and hence becomes an essential tool for operating modern IT systems” (Hartman 2016, p58 para 3). As Heinrich Hartmann speaks about IT systems, and there are many important uses of statistics. We would like to study and understand the data which range from banking, government, science, math, and …show more content…
According to Laura Delaney (2010), “the purpose of this type of analysis is to simply describe the sample group from which the data was collected” (p 43). As we collect data, we receive them from location measure and variation measures. Location measure is the mean, median and mode. The variation measure is the range, standard, deviation, and variance. The first set of data is used to find out the frequency of the data which could be found in the mean, median and mode. The second set of data is used to analyze how far apart the distribution of data found in the range, standard, deviation, and …show more content…
What makes inferential statistics so unique is if you want to examine a portion of a case, you could do that vise analyzing the whole matter. For example, you want to know the hitting average for all Major-League Baseball teams, but rather than finding it from all you pick 15 Major League teams which are going to symbolize a large group of Major-League baseball teams. Another example according to David D. Barrett, Allen W. Burton and Simon J. Bennett “3,684 throws made by 100 players in 7 collegiate baseball games was examined about the position, distance and active and inactive situations” (Barrett, Burton & Bennett 2002). Inferential statistics can be used in many ways, this way you could get your decision for your situation and your choice should result in estimation of the parameters and test the hypotheses. With the evaluation of the parameters and testing the hypotheses you will conclude beyond the data that you have and to make your decision using the data it will matter on the type of test that you use, for example, a t-test or
Introduction to the basic concepts of probability and statistics with discussion of applications to computer science.
For people who are not statisticians, they may wonder what statisticians do, and how statistics could be applied in daily life. Statistics: A Guide to the Unknown is a supplementary reading materials designed for general readers even if he or she did not learn enough knowledge of statistics, mathematics and probability. Besides, it could give statisticians a general understanding of the important role of statistics in society. This book also analyzes how statistics assists people to gain useful information from massive data sets. In order to form a more respected book, the editors invite many distinguished researchers in statistics as authors. The book consists of twenty-five essays from different fields, including public policy and social science, science and technology, biology and medicine, business and industry, and hobbies and recreation. Each essay provides readers a description of how statistical methods are applied to solve issues in that field.
Statistics enables us to organize and arrange a basket of data, to link up their relationships by using calculation and diagrams, to analyze the results, finally evaluate errors, generate conclusion from small group to large group. You can prove what you want by statistics, but it really sometimes lies by tricky stratified sampling, distorted graphs and dimness figures.
Chapter 12 introduces the reader to the true definition of statistics, without scaring them half to death. The book breaks statistics down in two parts: descriptive and inferential. The type that is dealt with in this chapter is descriptive statistics. The simple definition of descriptive statistics are that they are just numbers in different forms, for example, percentages, numerals, fractions, and decimals. The book gives an example of a grade point average being a descriptive statistic.
A researcher determines that 42.7% of all downtown office buildings have ventilation problems. Is this a statistic or a parameter; explain your answer.
n my eyes, statistics are everywhere. Basketball, for example, is a game of percentages and statistics. When I watch, I see numbers. Not the jerseys, but the stats behind each player, team, and game. If you asked me how last night's game went or how skilled I think a player is, I would answer in data. Statistics is how I interpret the world, especially basketball.
Specifically what my main goal in this paper is to help you understand what a Computer Systems Analyst is, what they do, things like those that explain everything about a Computer Systems Analyst. You could probably guess from the name of this job title that the main function of a Computer Systems Analyst is to determine how a computer system can best help something. Well this is exactly the key role of what they do is determine how a computer system can best serve a business or organization's needs. David P. Bieg says “You need to understand how systems interact, but you don’t really need to understand the core of every technology---it’s really about how information and process flows through the system.” Someone who is working as a Computer Systems Analyst is going to to have to be big-picture oriented and be able to understa...
Statistics Investigation In this investigation I have been asked to carry out a line of enquiry with the statistics provided within a Microsoft Excel spreadsheet provided by Edexcel examining board. There are various different statistics for different things, some examples include; age, IQ, year group, height, weight and many more. A total of 27 categories are shown on the spreadsheet. My teacher advised me to carry out two main tasks within the overall investigation. It was suggested that I carry out one line of enquiry with two pieces of quantitative information, and then one more investigation that could either be with one piece of quantitative information and one piece of qualitative or with two pieces of qualitative information.
Almost every year a hurricane blast through Florida and takes its toll on the business, industry and affects the lives and dollars of the company and its workers. One can ask themselves, "How do we prevent this from happening again?" This is usually what businesses and persons affected by a hurricane ask each other. What about a hospital? How would a hospital prepare for a hurricane? To complicate things more, how would a hospital prepare for a hurricane if the hospital is to operate 24 hours a day? This is the question that Pierre, Keith, Carol, Getta and James have proposed.
The standard deviation is a measure of dispersion reported with the mean. Measure of dispersion is a summary of the distribution around the measure of central tendency (Rubin & Babbie, 2014). For the purpose of this study, the central tendency utilized is the mode. In order to provide more information in regards to the variable of ethnicity and gender, the measure of dispersion is utilized, and in order to explain the measure of dispersion, standard deviation is utilized. Standard deviation is a descriptive statistic that explains how far away from the mode individual scores on average are located (Rubin & Babbie, 2014).
In evaluating statistical data one thing to consider is the measure that is used. By understanding the different statistical measurement tools and how they differ from one another, it is possible to judge whether a statistical graph can be accepted at face value. A good example is using the mean to depict averages. This was demonstrated by using the mean as a measure of determining the distribution of incomes. The mean income depicted was, $70,000 per year. At face value, it looks as though the sample population enjoys a rather high income. However, upon seeing individual salaries, it becomes obvious that only a few salaries are responsible for the high average income as depicted by the mean. The majority of the salaries were well under the $70,000 average. Therefore, the mean distributed income of $70,000 was at best misleading. By also looking at the median and mode measures of the income distributions, one has a clearer picture of the actual income distributions. Because this data contained extreme values, a standard deviation curve would have given better representation of salary distribution and would have highlighted the salaries at the high level and how they skewed the mean value.
Often uses random sampling to select a large statistically representative sample from which generalizations can be drawn.
Qualitative and Quantitative study designs both can be beneficial in research design. They both provide valuable options for researchers in the field. These techniques can either be used separately in a research study or they can be combined to achieve maximum information. This paper will define the terms qualitative and quantitative; describe the similarities and differences between each; discuss how qualitative and/or quantitative research designs or techniques could be used in the evaluation of my proposed research; and discuss why linking analysis to study design is important.
Whether or not people notice the importance of statistics, people is using them in their everyday life. Statistics have been more and more important for different cohorts of people from a farmer to an academician and a politician. For example, Cambodian famers produce an average of three tons or rice per hectare, about eighty per cent of Cambodian population is a farmer, at least two million people support party A, and so on. According to the University of Melbourne, statistics are about to make conclusive estimates about the present or to predict the future (The University of Melbourne, 2009). Because of their significance, statistics are used for different purposes. Statistics are not always trustable, yet they depend on their reliable factors such as sample, data collection methods and sources of data. This essay will discuss how people can use statistics to present facts or to delude others. Then, it will discuss some of the criteria for a reliable statistic interpretation.
Data Collection is the process of collecting information that will be utilized in the diagnostic process and eventually used to make business recommendation. In this data collection process, it is critical to ensure the highest quality of data possible. In the data collection component, the information is gathered on the specific department or organization such as inputs, design components, an...
