...Statistics in the Workplace Statistics is used every day in the workplace, and most of us do not even realize we are using statistics yet it aids every company in making improvements. Working in health care and having minimal knowledge of statistics it is easier to see statistics assists in virtually every area for showing areas that need or have improved. Descriptive and Inferential statistics are two types utilized in the workplace and statistics uses four different levels of measurement. The first level of measurement in statistics is nominal this level of measurement this level involves no ranking or order of the data. An example of a nominal measurement in the infusion center would be the different types of blood we administer that day. Whether it is A, B, O, positive or negative neither is placed ahead of the other and it is simply a category of measure. The second level of statistical measure is ordinal level, and it is a ranking system yet does not allow precise differences of measure (Bennett, Briggs, & Triola, 2009). The infusion center frequently conducts patient satisfaction surveys where patients rank how satisfied they are with certain services they receive. This is considered an ordinal level of measure, as there is not a similarity between the categories of satisfaction. Interval level of measure is the third form of measure in the statistical application and has the same interpretation throughout with an arbitrary zero point (Rice University (Lead Developer)...

I will need an extended period of laborious cogitation to assimilate the missive. This doesn't make any sense - bad statement. d. The number 2 is odd. Are we talking about an even number?

He’s cause for damage to the heart was the steroids, of which he was unaware of the consequences of taking the steroids at the time he took so there wasn’t any sort of health irresponsibility known otherwise. His chances to live 10-15 more years are very high so it’s one point investing in him. He has a family to take care of, wife and the 3 kids who he has to support till they are on their feet and so forth. He also has been a good supporting father as he’s already being supporting their dreams career wise and the future. So my first choice with all confidence would be Jerry. The number 2 choice is Ozzie because as LONG as he does not get back on his old ways HE does hold out some hope on society as a whole as long he does NOT revert back and does good in society by helping out and he no longer does any drugs - he really can have a useful and a prosperous and productive life. His chances of living after a successful heart transplant are another 10 years but only if he stays off the drugs and which is not really guaranteed but if he does he can be a very good mentor and a coach or a guidance for teens with troubled life as they are on drugs already. Since Ozzie have seen the side effects and losses because of the drugs, he can let the teens know it too and...

12 Angry Men

...Corridors of Transition between 12 Angry Men and 12 “I have always found that mercy bears richer fruits than strict justice”. Abraham Lincoln “The virtue of justice consists in moderation, as regulated by wisdom”. Aristotle ”Nobody gets justice. People only get good luck or bad luck”. Orson Welles Justice = mid-12c., "the exercise of authority in vindication of right by assigning reward or punishment;" also "quality of being fair and just," from Old French justice "justice, legal rights, jurisdiction" (11c.), from Latin iustitia "righteousness, equity," from iustus "upright, just" . The Old French word had widespread senses, including "uprightness, equity, vindication of right, court of justice, judge." The word began to be used in English c.1200 as a title for a judicial officer. Meaning "right order, equity" is late 14c. Justice of the peace first attested early 14c. In the Mercian hymns, Latin iustitia is glossed by Old English rehtwisnisse. To do justice to (someone or something) "render fully and fairly showing due appreciation" is from 1670s. This word, with such a strong connotation, influenced and formed the basis of many philosophical...

Qnt351 Data Analysis

...Week 2 Learning Team A Paper Parts 4 & 5 Levels of Measurement for Each Variable in the Study In the survey that Debbie Horner, the Human Resource manager, distributed to the company, there are different levels of data available for analysis. The question seeking information about the respondent’s gender is a nominal-level question. “The nominal level of measurement observations of a qualitative variable can only be classified and counted” (Lind, Marchal, & Wathen, p. 10, 2011). For analytical purposes the order in which the data is displayed makes no difference. The question regarding the division of work for the respondent, and the question regarding if the respondent is a member of management or supervision is also nominal. Also, the question pertaining to length is service is nominal because it only seeks one answer. The ten questions relating to how each respondent feels is interval-level data. The ten questions ask each respondent to rate his or her individual feelings on a scale of one to five. One is considered very negative and five is considered very positive. This is known as a Likert Scale. The Likert Scale is the most popular form of survey data collection because it is easy to assemble, the scale is more reliable, and produce more interval-level data (Cooper & Schindler, 2011). Data Coding After collecting the data, Sally, one the office support staff, began the task of coding the data. While some values were pre-determined other...

Numerology

...1 www.oldwitchcraft.com 2 www.oldwitchcraft.com 3 INTRODUCTION The science of numerology can be traced back thousands of years. The Chinese, Japanese, Greek, Hebrews, Egyptians, Phoenicians, early Christians, Mayans, and Incas all used some form of numerology to gain a deeper understanding of themselves and the universe. Numerology is perhaps the easiest of the occult arts to understand and use. All you need is the birth date and the complete name of an individual to unlock all of the secrets that the numbers hold. (Most authorities agree that the full birth name as recorded on your birth certificate is the name that must be used for all calculations involving name.) There are eleven numbers used in constructing Numerology charts. These numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, and 22. Larger numbers that occur from adding the numbers in the complete birth date or from the values assigned to each name are reduced by adding the digits together until the sum achieved is one of the core numbers. Merely add the components of the larger number together (repeatedly, if necessary) until a single digit (or the "master" numbers 11 or 22) results. Each of these numbers represents different characteristics and expressions. Master numbers are the only exception to rule of reducing to the single digit. The master numbers 11 and 22 are intensified versions of the single digit number they replace (2 and 4). These numbers suggest a potential for a high degree of learning and/or achievement...
