Definition of statistics Essay Example for Free

Definition of statistics Essay According to Lind, Marchal, and Warhen (2011), the definition of statistics is that it is the science of data. It involves collecting, classifying, summarizing, organizing, analyzing, and interpreting numerical information (Chapter 1). There are different types and levels of statistics. For example Descriptive statistics utilizes numerical and graphical methods to look for patterns in a data set, to summarize the information revealed in a data set, and to present the information in a convenient form. The four elements of descriptive statistical problems are the population or sample of interest, One or more variables (characteristics of the populations or sample units) that are to be investigated, Tables, graphs, numerical summary tools, and the identification of patterns in the data Also there are Inferential statistics that utilizes sample data to make estimates, decisions, predictions, or other generalizations about a larger set of data. There are 5 elements of inferential statistical problems: The population of interest, one or more variables (characteristics of the population units) that are to be investigated, the sample of population units, the inference about the population based on information contained in the sample, and a measure of reliability for the inference. When it comes to the role of statistics in business decision making it is applied in many ways in terms of consumer preferences or even financial trends. For example, managers across any type of business unit formulate problems, they decide on a question relating to the problem and then form a statistical formulation of the question is used to determine answers to all of the above. An example of a business question may be how many calls are answered on average in a call center and how can we increase the numbers of calls answered per hour. Another example may be how we can increase the number of accounts we open each week, and who is opening the Most accounts  and what is it that is aiding in the success of those individuals. Clearly there are many questions but determining the right questions that can be measured with statistical data is key to getting the right answers. References Lind, D. A., Marchal, W. G., Warhen, S.

The Sin of Hypocrisy in Nathaniel Hawthornes The Scarlet Letter :: Scarlet Letter essays

The Sin of Hypocrisy in The Scarlet Letter The Scarlet Letter by Nathaniel Hawthorne is about the trials and tribulations of Hester Prynne, a woman living in colonial Boston.   Found guilty of adultery,   Hester's punishment is to wear a visible symbol of her sin: the scarlet letter "A."   Through the book, the reader comes to know Hester, the adulteress; Dimmesdale, the holy man Hester had the affair with; and Chillingworth, the estranged husband of Hester who is out for revenge.   The Scarlet Letter examines the interaction of these characters and the reaction of these characters to Hester's sin.   However, the greater sin that Hawthorne deals with in The Scarlet Letter is hypocrisy.   Hypocrisy is the practice of professing beliefs, feelings, or virtues that one does not hold or possess.   All three main characters, Hester, Dimmesdale, and Chillingworth, commit the sin of hypocrisy. Hawthorne shows that hypocrisy is indeed a sin by punishing the offenders. Hester Prynne is a strong, independent woman who deals with her sin of adultery very well.   Instead of running away from it, she lives with it and accepts her punishment.   However, while succumbing to the will of the court, she does not for an instant truly believe that she sinned.   Hester thinks that she has not committed adultery because in her mind she wasn't really married to Chillingworth.   Hester believes that marriage is only valid when there is love, and there is no love between Hester and Chillingworth.   In the prison, defending her actions against him, she declares, "Thou knowest, thou knowest that I was frank with thee.   I felt no love, nor feigned any" (74). Then, later, speaking to Dimmesdale, Hester further imparts her belief that she has not sinned, saying, "What we did had a consecration of its own.   We felt it so" (192).   Therefore, Hester, in her mind, has not committed a sin. The fact that she accepts the courts decision so meekly and wears the scarlet letter denoting her as an adulteress is the first way in which she is hypocritical.   Hester, although she does not believe she has sinned, portrays herself as a sinner by wearing the scarlet letter without complaint.   Over the ensuing years, Hester endures the shame and ridicule brought about by the scarlet letter.   However, the true source of

The little short film on the site titled â€Å"Stile Post† or the telephone game made a little impact on how I view our world today. They start off the film with Miriam the little girl basically picking on Paul, the only colored kid In the class, by saying that Paul never washes, and passing it to the next person. That person then passes that little bit of information to the next kid, who passes It to the next kid, and so on.

How to Avoid a Computer Disaster (4 Tips on Backing Up Data)

How to Avoid a Computer Disaster (4 Tips on Backing Up Data) How to Avoid a Computer Disaster (4 Tips on Backing Up Data) Most college work is now written on computers, not by hand. There are many advantages to this, since you can edit work more easily on screen, and a printed paper is usually much easier to read. However, one benefit of pens is that they rarely break and delete several hours of your work. Computers, meanwhile, can crash without warning (especially if you’re prone to spilling your coffee on your laptop). As such, we’ve got a few tips on backing up data to share. 1. Save Regularly The first and most basic tip we can offer is to save your work regularly. One way to do this is to configure the auto-save options in your word processor to create a recovery file every few minutes. If your computer does crash, this should stop you from losing too much work. You can’t rely on auto-save completely, though, so make sure to save manually as well. Just hit Ctrl and S. Its that easy. 2. Using Multiple Saves In fact, while you’re saving manually, make sure you have at least two copies of any file you’re currently working on. That way you’ll have a backup in case you accidentally overwrite one. If you’re working on a longer document, like a thesis or dissertation, you might even want to save each new draft separately. This protects you against losing information, but also lets you compare different versions of a document during the editing process. 3. Backing Up Important Files Most important of all is not putting all of your (electronic) eggs in one (computer) basket. In other words, create a backup of all the important information on your computer. This applies to personal stuff (photos, music, etc.) as well as your college work. This could be on an external hard drive, via a cloud service, or on other storage media (e.g. CDs or DVDs). That way, if your computer does break, you have a way of quickly restoring lost data. Probably not a floppy disk, though, unless your computer is very, very old.(Photo: George Chernilevsky/wikimedia) How often you back up data is up to you, but we’d suggest doing it at least once a month. 4. Data Recovery Maybe you’ve found this blogpost because your computer has already crashed and won’t start again, so now you’re googling desperately for a solution. If so, we might have the answer. Data recovery is the process of retrieving data from a hard drive. If it’s just a case of having deleted something by accident, there’s a good chance you can retrieve it with the right software. But if the hard drive is damaged, recovering data is more difficult. Your college’s IT department might be able to help with this. If not, there are professional services that can. Data recovery can be expensive, though, so backing up your work before it comes to this is wise!

A Study on the Worlds Educational System

A Study on the Worlds Educational System A number of similarities as well as differences exist between the K-12 education system in the United States and the 8-4-4 system in Kenya. The similarities are such as the age at which children enter into school. In both countries children enter school approximately at the age of five or six. Also, the initial grade of commencing education is termed as kindergarten in both countries. In addition, one has to spend twelve years both in primary and high school education level before qualifying for tertiary education which may be in the universities or colleges despite the difference in the grading system within the twelve years. Another similarity between both systems is that one can access the K-12 or 8-4-4 education from both private institutions as well as public institutions. Moreover both systems enjoy funding from the state governments as well as federal and local government but those attending private institutions are self- sponsored that is they have the responsibility of payi ng their tuition fees to the institutions. Also in both systems one has to perform at a certain set average standard at the examinations provided in each level in order to qualify for the next level. In both systems students traditionally proceed from one level to the subsequent one as a â€Å"class† upon the completion of each academic year. In both countries it is compulsory to enroll in to the education systems after attaining the minimum required age and the parents or guardians who fail to abide by this law risk been prosecuted in accordance to the laws of the countries. However these laws are much more strict and effective in the United States as compared to Kenya where laxity has been observed in the enforcement of the compulsory education laws leading to a very dismal enrolment of children in schools especially in the parts of the country inhabited by the pastoralists’ communities. Nevertheless, in both countries there is no a compulsory level of the education system which one should go up to before leaving the education system. One is free to undertake his or her studies up to primary level, high school level or even college or university level in accordance to his intellectual capabilities as well as financial strength. In both countries student loans and scholarships are provided in the university level to enable students meet their tuition costs as well as other related costs such as those incurred while undertaking research projects (Brint in the primary and high school level the school year usually starts immediately after the customary summer recess that is in August and sometimes in September while in Kenya the school year commences in January immediately after the New Year festivities. In the U.S, students have only six hours of schooling per day while in Kenya students spend almost ten hours in school on a daily basis. In the 8-4-4 system, students in primary and high school level break for holidays three times per year while i n the K-12 system students have only one long holiday which is slated during the summer season. Another difference between the systems is that in the K-12 system, primary education takes only five years while in the 8-4-4 system it takes eight years. In the K-12 system; upon graduating from primary school, one proceeds to middle school before proceeding to high school while in the 8-4-4 system one directly joins high school upon completing primary education. In the U.S each state governs the public education unlike in Kenya where the public education system is governed by the central government. In Kenya, one is free to obtain admission to any public school of his or her choice within the country while in the U.S the right of entry to a certain public school is mostly granted on the residential basis. Also the grading scale used in the 8-4-4 system is quite different from the one applied in the K-12 system. The rate of enrollment into the K-12 system is quite high as compared to the 8-4-4 system. Besides, teacher employed in the primary level in the K-12 system are graduates of early childhood development degree program while in the 8-4-4 system majority of primary school teachers possess only a certificate from a teachers training college (Herbst, 1996)

Beowulf Essay Example | Topics and Well Written Essays - 500 words - 3

Beowulf - Essay Example Thesis statement: Does Beowulf in the poem possess heroic qualities that can be termed under the real qualities of an epic hero? The most important quality of Beowulf that makes him an epic hero is his heroic quality. For instance, like a real hero, Beowulf was ready to travel a great distance to undertake dangerous tasks. When Hrothgar faced trouble from Grendel, like a real hero, Beowulf left his homeland (Geatland), killed the Grendel the monster and saved all. But Burton Raffel criticizes that the author does not give ample importance to Beowulf’s fight with monsters and dragons (Raffel xi). Beowulf praises Hrothgar on his nobility and brevity. This proves that he possesses the heroic quality of courtesy. When he entered the land of Danes, he left his weapons on the shore. This proves his courtesy towards the king and his people. Besides, Beowulf was ready to do anything to prove his courtesy. Beowulf was a brave warrior. For instance, he fought and killed Grendel the dragon, and his mother, another dragon. Besides, Beowulf reveals Hroogar that he did defeat five giants and chased them from the earth. Beowulf possessed the quality of loyalty. He proved his loyalty towards the king and his people by killing Grendel the dragon. Later, when he became the king, Beowulf did not allow his warriors to fight against Grendel’s mother. Instead, he proved his loyalty towards his people by killing Grendel’s mother by his own. Beowulf’s success as a leader proves his military skills. Besides, he was able to maintain a group of warriors with him to help in critical situations. He very well knew that his warriors may not be helpful in the fight with Grendel and his mother. So he went alone to face those demons/beasts /dragons. This proves his military tactics. Summing up, one can see that the heroic qualities possessed by Beowulf helps him to be a real epic hero with heroism, courtesy, bravery, loyalty, leadership
