Central tendency and dispersion Upon performing data analysis using descriptive statistics, skew values and central tendencies, as well as, dispersion of data was visual evident. Central tendency is basically the cluster of data values while dispersion deals with the range of data values and how they are spread out. Additionally, dispersion reflects the amount of variation in the data. In the category of education, the central tendency focused on range of 10 – 12 years at 51 percent and 12 – 18 years slightly below but still significant at 39 percent. These values make up 90 percent of the data for this category. Regarding salary, dispersion of data played a significant role as the data was widely distributed ranging from $10,000 to $83,000 annually. The central tendency revolved around the range of $15K - $36K, for a total of 63 percent while greater than $36K made up 24 percent and less than $15K comprised 13 percent. Another area which illustrates central tendency and dispersion of data is age with a range in years of 18 to 64. Forty-seven percent fell in the age range of 32 – 53 while those younger than 32 represented 33 percent and those older than 53 characterized the lowest percentage for this category. Other demographic criteria such as Hispanic versus Non-white, Female, Southern Resident, Union, Married, and type of Industry were skewed due to limited options of variability with the exception of the Female category which had a balanced outcome of 47 percent female to 53 percent male. The findings represent a significant showing for central tendency in categories that contained greater ranges such as Age, Salary, Wage, and Education while groupings that were defined by “yes or no” variables were more skewed in…...

Creative Tendencies

...I have learned through this chapter that creative problem solving occurs less frequently then analytical problem solving. I have never really considered myself a real creative person, although I have creative my own unique and creative tendencies. As I learned many people think of creativity as being “one-dimensional” (me included) and also many of us have built up conceptual blocks which limits and blocks our problem solving effectiveness. After reading this chapter, I have a greater perspective on creativity and how to achieve it through the four types of creativity – incubation, imagination, improvement, and investment, all in which I can use in a variety of ways to bring out my creative side. On this assessment I had completed in chapter three, I picked out five statements that would indicate creative tendencies and five statements that I would consider not to indicate creative tendencies. Creative tendencies would include: Daydreaming has provided the impetus for many of my more important projects (B). I believe that daydreaming gives you the opportunity to think creatively, it gives you a chance to really dive into your own creative thinking and think outside the box. I like hobbies that involve collecting things (C). I disagreed on this; I’m more of a physical type of person and an active type of person who enjoys watching and playing sports, but I think I need to think of a more creative hobby that I may enjoy. Inspiration has nothing to do with the......

Central Bank

...The Role of Central Banks We operate today in modern advanced economies which rely on a system of fiat money. The agency that controls this system is known as a central bank. A central bank has the power to increase and decrease the amount of currency made available in an economy. Furthermore, the set of actions that make this possible is called the monetary policy and there are different tools that central banks use to operate a stable economy. The two agencies which control the European monetary policy are called the European Central Bank and the Bank of England. In US, the central bank is called the Federal Reserve. This essay will provide fact and information to what extent central banks control our economy. Initially, central banks are important institutions of our advanced modern economy. Changes in the money supply can affect our economy when it comes to rate of inflation, unemployment, prices and production of goods. Because of the link between the amount of money in an economy and the inflation rate, central banks will act as a price guardian. Their policy is to keep the inflation rate as close to the inflation target as possible. For that reason, central banks are able to increase and decrease the available currency in an economy. Therefore, central banks should be seen as a guardian of inflation stability, rather than a guardian of price stability. There are several tools that central banks use to fulfil their role as a guardian of inflation stability to......

Religious Tendencies

...Religious Tendencies Religion, one little word that can spark the largest argument that one has ever heard. But what is religion? Religion is the act of believing in a higher deity or deities that can control the cosmos, or not believing. It is the way society is grouped based on who they suppose controls life. For example in the Christian religion people believe in the holy trinity. Over the decades society has evolved and with the advancement of science and math some aspects of religion have been disproved. Yet though all decades of time religion has survived and is still a predominate part of our society. Religion has been able to survive over generations of scientific and mathematical advancement for many different reasons; its place in our history, politics, human necessity, and belief. First and foremost, Religion has always been predominating in our history. When our Neanderthal ancestors were first beginning to civilize, they needed a way to explain why things happened a certain way. They had no or very little math and science. So in order to explain the sun rising and falling without fail they came up with a god or gods. They used these religious deities to explain the cosmos. Why everything happens and why. This is how the Greeks came to believe in Zeus, Hades, and Athena. As Human being we have a thirst to know why things happen. In the past without the science and technology we have today we had no way of knowing that the Aztec god Tlaloc didn’t bring the......

Tendency and Coincidence Evidence

...TENDENCY AND COINCIDENCE EVIDENCE IN CRIMINAL CASES (Parts of this paper are a repetition of a paper I prepared for the Legal Aid conference last year and which was published in Bar News Criminal Law Special Edition.) Ian Barker QC 1. I have practised law from a time beyond which the memory of man runneth not. At least, that is how it feels. During those years I managed, I think, to develop a slippery hold on fundamentals of the law of evidence, from the myriad cases on the subject. I was recently heartened to read something written by Sir James Stephen in about 1886 in the Introduction to his Digest of the Law of Evidence1. Speaking of the difficulty in finding concise guidance to the law of evidence he said: No such work, so far as I know, exists; for all the existing books on the Law of Evidence are written on the usual model of English law-books, which, as a general rule, aim at being collections more or less complete of all the authorities upon a given subject to which a judge would listen in an argument in court. Such works often become, under the hands of successive editors, the repositories of an extraordinary amount of research, but they seem to me to have the effect of making the attainment by direct study of a real knowledge of the law, or of any branch of it as a whole, almost impossible. The enormous mass of detail and illustration which they contain, and the habit into which their writers naturally fall, of introducing into them everything which has any...

Central Tendencies

...Andrea Roberson PSY 351 Monstrous Methods for Teaching Central Tendency Concepts This article discusses a new creative approach to introducing central tendencies to students. It involves incorporating gaming techniques and concepts to make learning the new material fun and interactive. Math can be rather difficult for students of all ages. However, with this learning tactic, one may over look the difficulties and focus on the entertaining aspect. The “game” begins with the teaching of basic knowledge of central tendencies – mean, median, and mode. From there, students are introduced to the game and given a story about evil monsters and their means of survival. The story occurs in a dungeon and all the exits are blocked with monsters. There are three exits, each marked with the central tendency that describes the size of the monsters standing between that door and freedom. They are given an opportunity to choose from three doors marked mean, median, and mode with numerical values. There is no particular order the doors should be marked for each game. For example, door number one may be marked as “mode = 75” one game and marked as median = 7 for the next. Behind the door marked with “the mode” are many small monsters and a few giant monsters. Unfortunately, students who choose this door are typically eaten. It helps the students understand that the numeric value of the mode describes the different variety of creatures behind the door and which kind is most abundant......

Central Bank

...Academic supervisor: Dr. Abdlsalam Alhamad To begin with, Dr. Adel Sharkas claimed and addressed his case and point of view of the central bank of Jordan and its achievements and accomplishment. He also spoke about his personal life and how he became the person he is now. As an audience member, I was significantly inspired and ideas of what I can do to grow as a person flood into my thoughts. Background Moreover, Jordan set out preparations to establish the Central Bank of Jordan (CBJ) in the late 1950s. The Law of the CBJ was enacted in 1959. Thereafter, its operational procedures were commenced on the first day of October 1964. The CBJ succeeded the Jordan Currency Board which had been established in 1950. The capital of the CBJ, which is totally owned by the government, was increased gradually, from one million to 18 million Jordanian Dinars. The CBJ enjoys the status of an independent and autonomous corporate body, although its capital is owned entirely by the government. Objective The law establishing the CBJ stipulates that "the objectives of the Central Bank shall be to maintain monetary stability in the Kingdom, to ensure the convertibility of the Jordanian Dinar, and to promote the sustained growth of the Kingdom's economy in accordance with the general economic policy of the government." The most important objective of the central bank is to achieve the stability of the exchange rate is crucial for continuous economic growth; also the control of the......

Central Theorum

...Methodology for monitoring a process to identify special causes of variation and signaling the need to take corrective action. • When special causes are present, the system said to be statistically out of control. • If the variations are due to common causes alone, the process is said to be in statistical control. • SPC relies heavily on control chart A typical quality control plan requires sampling one or more items from a production process periodically, and making the appropriate quality measurements. • Usually more than one item is measured each time to increase accuracy and measure variability. • The chart helps the quality control person decide whether the center (or average, or the location of central tendency) of the measurement has shifted. • Hugging the center line: sample taken over various machines canceling out the variation within the sample. • Hugging the control limits: sample taken over various machines not canceling out the variation within the sample. • Instability: difficult to identify causes. Typically, over-adjustment of machine. • Always, R-chart analysis before the x-bar-chart analysis. • Hugging the center line: sample taken over various machines canceling out the variation within the sample. • Hugging the control limits: Interpreting patterns in control charts [pic] Process capability • Particularly process characteristics study: Performed over a period......

Central America

...the internal political and cultural tensions in the Central America region from the colonial period to the present day? Describe these turning points in terms of the people who were involved in creating change and the controversies of the times. The history of Central America is considered to be a colorful one but rather complicated and even tragic because a lot of historical events took place and influenced greatly the political, economic and cultural development of the Central America region. (Perez-Brignoli, 1989) It is known that Central America has seen wars and dictators, foreign interventions and economic crises. (Booth & Walker, 1999) To my mind, the three turning points that have created the internal political and cultural tensions in the Central America region from the colonial period to the present day are the following ones: • Colonization of Central America by Spain in 1523. • When Central America declared Independence in 1821 and on June 1, 1823 five countries of Central America were united. • Revolution in 1944-1954 in Guatemala. The first turning point can be related to the period of colonization. The local population tried to stand against the Spaniards but Indian tribes had no chances to win. All the cities were captured by the colonizers. Some cities were burned and great deals of local people were killed. The Spaniards had control over the whole territory of Guatemala and other countries of Central America. The life of local population changed......

Measure of Central Tendency

...“Measure Of Central Tendency”? A particular value that attempt to illustrate a set of data by classifying a central position within the set of data is known as the measure of central tendency. The central tendency is distinguish with its dispersion or in other words the variability. It is important to summarize a set of data with a single value of data when interpreting and analyzing data, as it serves the purpose and give a representative value for the overall data. The most common measures of central tendency are the arithmetic mean, the median and the mode. A central tendency can be calculated for either a finite set of values or for a theoretical distribution, such as the normal distribution. Occasionally authors use central tendency to denote "the tendency of quantitative data to cluster around some central value." [1][2] Mean: It is also known as the arithmetic average, mean is the sum of value of all the observation in a set of data divided by the total number of the observations. Median: when values are arranged in a descending or ascending order, the middle value in the distribution is known as the median. Mode: It is the most repeated or commonly occurring value in the distribution. [1]  Dodge, Y.

Measures of Central Tendency

...The real estate market has changed since the time when “location, location, location” was the only factor affecting house pricing. Today potential home buyers take into considerations different variables ,such as number of bedrooms, square footage and distance from the city.. The variable that team B found to be the most important when it comes to buying a home is; home selling price, number of bedrooms, and location. For all of the chosen variables, Team b calculated the measures of central tendency and dispersion. Team b did the calculations on the two most common measures of central tendency, the mean, and median. In the real estate data researched by team B, the team found that the average price that homebuyers are looking for starts at around $190,000 with a maximum price of $ 300.000. These are the prices that the average homebuyer is looking to pay. This gives a difference of $110,000 between the two prices. The mean or average price that buyers are looking for would be $200,000. According to "Trulia" (2012), In Houston Texas the average selling price for a single family home is between $ 111,000 to 136,000. The high end selling price on average for a single family home in Houston Texas is $173,000. The mean or average home selling price for a single family home in Houston Texas is $140,000. This price is still within the $190,000 to $300,000 range that most buyers are looking for. The variance in this data would be $ 973, 000,. The standard deviation would...
