How Bar Graphs Are Used to Display Data

How Bar Graphs Are Used to Display Data A bar graph is a way to visually represent qualitative data. Qualitative or categorical data occurs when the information concerns a trait or attribute and is not numerical. This kind of graph emphasizes the relative sizes of each of the categories being measured by using vertical or horizontal bars. Each trait corresponds to a different bar. The arrangement of the bars is by frequency. By looking at all of the bars, it is easy to tell at a glance which categories in a set of data dominate the others. The larger a category, the bigger that its bar will be. Big Bars or Small Bars? To construct a bar graph we must first list all the categories. Along with this, we denote how many members of the data set are in each of the categories. Arrange the categories in order of frequency. We do this because the category with the highest frequency will end up being represented by the largest bar, and the category with the lowest frequency will be represented by the smallest bar. For a bar graph with vertical bars, draw a vertical line with a numbered scale. The numbers on the scale will correspond to the height of the bars. The greatest number that we need on the scale is the category with the highest frequency. The bottom of the scale is typically zero, however, if the height of our bars would be too tall, then we can use a number greater than zero. We draw this bar and label the bottom of it with the title of the category. We then continue the above process for the next category and conclude when bars for all categories have been included. The bars should have a gap separating each of them from one another. An Example To see an example of a bar graph, suppose that we gather some data by surveying students at a local elementary school. We ask every one of the students to tell us what his or her favorite food is. Of 200 students, we find that 100 like pizza the best, 80 like cheeseburgers, and 20 have a favorite food of pasta. This means that the highest bar (of height 100) goes to the category of pizza. The next highest bar is 80 units high and corresponds to cheeseburgers. The third and final bar represents the students who like pasta the best and is only 20 units high. The resulting bar graph is depicted above. Notice that both the scale and categories are clearly marked and that all the bars are separated. At a glance, we can see that although three foods were mentioned, pizza and cheeseburgers are clearly more popular than pasta. Contrast With Pie Charts Bar graphs are similar to pie chart since they are both graphs that are used for qualitative data. In comparing pie charts and bar graphs, it is generally agreed that between these two kinds of graphs, bar graphs are superior. One reason for this is that it is much easier for the human eye to tell the difference between the heights of bars than wedges in a pie. If there are several categories to graph, then there can be a multitude of pie wedges that appear to be identical. With a bar graph, it is easier to compare heights a know which bar is higher. Histogram Bar graphs are sometimes confused with histograms, probably because they resemble each other. Histograms do indeed also use bars to graph data, but a histogram deals with quantitative data that is numerical rather than qualitative data, and of a different level of measurement.

English - Essay Example This paper is a critical evaluation of food insecurity in Nigeria, detailing the causes, effects as well as responses being made to solve the dilemma. Food Insecurity in Nigeria Nigeria is a West African country, where food insecurity has continued to compromise the health and lives of citizens especially children, who are most vulnerable. Statistics indicate that more than 40% of children in the country are suffering from chronic malnutrition, which is a major threat to the future of this generation (Omotor 2009). This is due to the fact that malnutrition is a common recipe for poor growth and development in children, which may lead to poor academic performance and intellectual development. It is sad to note that the government of Nigeria is doing little to rescue these children. One way of doing this would be to introduce a free feeding system in government schools, whereby these children would be provided at least with a single meal containing all the basic requirements of a balan ced diet. In this context, the government should observe what countries such as Ghana are dealing with malnutrition in school going children. Apparently, Ghana has already put the system to work, with the government allocating $347.4 million to the program, which will be running for 5 years (Alderman 2009). It is said that the government of Nigeria had plans to execute a similar program but it has been observed that such a plan was never implemented hence the high rate of malnutrition in children. It may be important to note that approximately 60% of Nigeria’s population is malnourished (Omotor 2009). Rural urban migration in Nigeria is also a problem, which has contributed significantly to food insecurity in the country. This is due to the fact that it encourages the movement of young and able bodied citizens from the rural areas, leaving the weak and the vulnerable people to engage in food production. It is important to note that, in order to realize viable food production, a farmer requires putting a lot of efforts in caring for the crops thus the need for manpower to perform activities such as weeding, spraying pesticides, harvesting among others. In this context, Nigerian farmers in the rural areas are faced with scarcity of human resources, which has resulted to an increase in wages demanded by manual laborers, who take advantage of the high demand for their services. Consequently, this has made it difficult for farmers to afford the costs, especially due to the poverty factor, such that they have developed a habit of skipping these important activities (Olayemi 2003). The government has played a major role in facilitating this problem due to the fact that it has neglected the rural areas by failing to improve social amenities and infrastructure, which has continued to discourage people, especially young school leavers, from settling in these areas. Lack of decentralization of resources and Corruption in the government have been identified as majo r contributing factors, which have slowed down development such that majority of roads especially in the rural areas are in total disrepair or absent all together. With impassable roads, it becomes difficult and expensive to transport farm products form producing areas to the markets, which combined with high fuel prices results to increased food

Importance of Language Diversity on Multinational Organisations Term Paper

Importance of Language Diversity on Multinational Organisations - Term Paper Example If we flip back to the pages of our history, the very idea of a single language has not proved to be so beneficial. For example, there was a time when Latin was enforced as a common language. But due to the various kinds of people living in Europe, a variety of languages sprang out of this one language and provided us with the different cultures that we look upon today. (Orban, 2008)  In order for the European economy to run smoothly, it is mandatory to recognize the various lingual problems faced by the multinational firms. These types of companies operate on a worldwide basis involving a constant exchange of goods and manpower among their subsidiaries. Due to the number of countries included, various languages are functional in this business. Hence, language problems arise, and the big challenge is to remove these linguistic and communication problems without causing any harm to the largely depended upon the socio-economic infrastructure of the firm. (LINEE, n.d)  A very fine e xample that demonstrates the causes and consequences of linguistic problems is the multinational operations held by the military. Cultural diversity in a military army can have both positive and negative impacts on a mission. The effectiveness of a mission can be reduced by a lack of proper communication due to the use of a variety of languages and inability to communicate in a single language. Lack of the required level of coordination along with the lingual limits on the exchange of information is also a result of language diversity, leading to a weakening of the task. For example, the multinational mission at the Kabul International Airport (KAIA), although it was successful, had to face problems due to lingual differences. For instance, people were forced to receive medical help outside the Headquarters, as the Spanish medics had no command on English.   Culture refers to the ways information is exchanged in a particular group in order to conceive the desired meaning among the people. These ways include solid goods and non-verbal language. Cultures may be divided at a national level, religious level, racial level, gender level, etc., and their goal is to express themselves as superior to the others. (Diversity RX, 2003)  Language is actually one of the most important components that define a culture. The other factors include the way of dressing, greeting, eating, etc. hence, if members of a group unanimously agree to change the whole system of their culture, the language goes with it. To demonstrate this, let us take the example of a group of rich teenagers belonging to Pakistan. This group includes children from different areas of the country, speaking a variety of languages. Through media, they are deeply influenced by western culture causing them to eat, greet, dress, and even talk like the westerners. So down the sewers goes lingual diversity.

Is There Difference Between True And False Philosophy Essay

Is There Difference Between True And False Philosophy Essay The distinction between truth and false is often perceived as an easy distinction to make, like a yes or no question. If you lie about something for example, then what you are saying is false, if you tell the truth then it is true. This is one of many misconceptions in life; the complexity behind the absolute distinction between truths and falsities is immense. How can an idea be judged to be true or false? One might say that a correct fact is true and an incorrect statement is false though the answer varies depending on the area of knowledge from which the statement is perceived. However, in order for there to be an absolute distinction there must be an absolute truth. In this essay I will question the existence of an absolute truth in order to determine whether or not there is an absolute distinction between what is true and what is false. In order to answer the topic question one must first seek to define certain terms/parts of the question the first of which is true. What is truth? Different sources attempt to answer this question in different ways. The big dictionary in Ms. Thorntons room defines it as anything that is public and independent of anyones belief; Merriam Websters English dictionary as something eternal that is in accordance with fact or reality; Dicitonary.com believes it is a judgment or proposition; Michael Woolman, in his book Ways of Knowing, believes it is something that is logically necessary. The struggle to accurately define truth is partially due to the fact that we are unable to determine whether or not truth is relative. The second term we must define is false. Merriam Webster believes that something that is false is nor genuine, nor faithful, nor loyal and is also lacking in naturalness and sincerity. Dictionary.com defines a falsity as a declaration of what is untrue and perhaps treacherou s. Lastly, we must define absolute which is perhaps a more concrete word than the preceding two; however it is significant to this paper to define it. Absolute refers to having no exception, restriction or qualification. In order for there to be an absolute truth, there must be proof. In order to prove an absolute truth, one must have a system of proof with which one can deduce the truths validity in every single situation and under every singly condition in eternity. An absolute truth must be true for all eternity. It must also remain unchanged forever and since we cannot determine whether this is true, and therefore any claim of absolute truth is ridiculous. Some might argue however that by making this statement, I am making an absolute claim. This is however false because there is a possible circumstance under which this claim could not have existed before people could reason. According to hubpages.com The propositional statement: There are no absolutes, is definitely not syntactically absolute, and not absolute in any real cognitive sense. It is a fact, that truth is not an object and does not exist without a mind, and hence impossible to be eternal. It is a fact, that truth is bound within the d omain of concepts, and hence impossible to be eternal. It is a fact, that anything claimed as eternal, cannot be proven to be the case, because eternity does not exist in order to be used in the construction of any logically deductive proof. It is a fact, that no claim of truth for anything absolute, can be proven to be true by any stretch of the imagination. In math however we have a set of rules that can define an absolute truth. According to Adam Richards, who holds a degree in philosophy from Oxford, in mathematics we can define an absolute truth or falsity because we precisely define the rules of mathematics. In reality, we need to measure what we want to know, and since these measurements can never be exact enough, an absolute truth cannot exist. How true or false something is depends on how accurate our measurements were but in the purely deductive world of mathematics, we can define exactly true/false statements. I do not fully agree with Richards because I dont believe that everything in life is a mere calculation however I second his reason for the presence of absolute truths in mathematics. Outside of math any claim of an absolute truth is one that is either based on religious beliefs or is related to religion in one way or another. This is because they are claimed to be given by god. It is safe to say that everyone will agree with the fact that an absolute truth mandates a god due to the fact that it must be eternally true. Without a god there would be no absolute truth because there would be no eternity in the claim. To discredit theses claims, even though most of the words of god we know today have not been changed, we cannot prove that they will remain unchanged eternally. All bibles and scriptures have undergone changes and revisions by humans who have tailored them to suit their tastes. Humans are not absolute, and have no system for preventing change to anything that is supposedly absolute (hubpages.com). In conclusion, there is no absolute truth due to our inability to prove a claim eternally, and therefore no absolute distinction between what is true and what is false. Something that is not true is automatically false because there is no third option. If it is partially true or partially false than one can say that it has a true claim and a false claim however it is still classified as either true or false.

Shake Down the Thunder: The Creation of Notre Dame Football :: essays research papers fc

  Ã‚  Ã‚  Ã‚  Ã‚  For as long as I can remember I have been a Notre Dame football fan. My father is to credit for getting me into it. He brought us to South Bend a couple of time for some games and I was just amazed by the campus and the history of the football program, so it was no surprise that I chose this particular book. Shake Down The Thunder: The Creation of Notre Dame Football was written by a man named Murray Sperber who was a sports writer interested on why fans were so into college football. Because of his interest Sperber decided to go around the country to certain college campuses to do research on this. He started with the University of Notre Dame because he was aware of the history and the passion of their football program, he was also aware of the appreciation Notre Dame had from their fans. This book deals with they history of Notre Dame football including the nation championships, the players, the coaches, and the program itself. It explains exactly what happened thought out its history, the reality behind the myths so to speak. Notre Dame was very kind to Murray Sperber in that he was given many privileges that other authors of books regarding Notre Dame football were deprived of. These privileges allowed Sperber to do research on Notre Dame from a different point of view and in his research he found documents that jumpstarted his interest to actually write this fantastic book. Sperber found the actual letters that Knute Rockne wrote to different people, which contained a lot of unknown information about Notre Dame football. These letters were found in the basement of the library and were unopened; apparently they had been hidden there since his death. Theses letter gave Sperber a side of Notre Dame football that no one has ever seen. As I said before, this book deals with the beginning of Notre Dame football and in a time of anti-Catholicism, helped people become more accustom to this religion. It reveals the real personalities of some of the most well known people affiliated with Notre Dame, including Jesse Harper, George Gipp, Father John O'Hara, Elmer Layden, Frank Leahy, and Grantland Rice, but most of all Kute Rockne was at the center of everything. The book gave Knute Rockne all of the credit for making Notre Dame football what it is today.
