...1. The data in the Excel spreadsheet linked below give the ages and salaries of the chief executive officers of 59 companies with sales between $5 million and $350 million. The correlation between age and salary can be characterized as: * 1. Strong and positive. * 2. Strong and negative. * 3. Weak and positive. 4. Weak and negative. By running “correlation” under “data analysis” in excel, we could obtain the following output: | Age | Salary | Age | 1 | | Salary | 0.127555 | 1 | Since r value is 0.127555, positive but far away from 1, the correlation between these two variables is weak and positive. In this case, choice “3” is the right one. Age | Salary ($thousands) | 53 | 145 | 43 | 621 | 33 | 262 | 45 | 208 | 46 | 362 | 55 | 424 | 41 | 339 | 55 | 736 | 36 | 291 | 45 | 58 | 55 | 498 | 50 | 643 | 49 | 390 | 47 | 332 | 69 | 750 | 51 | 368 | 48 | 659 | 62 | 234 | 45 | 396 | 37 | 300 | 50 | 343 | 50 | 536 | 50 | 543 | 58 | 217 | 53 | 298 | 57 | 1103 | 53 | 406 | 61 | 254 | 47 | 862 | 56 | 204 | 44 | 206 | 46 | 250 | 58 | 21 | 48 | 298 | 38 | 350 | 74 | 800 | 60 | 726 | 32 | 370 | 51 | 536 | 50 | 291 | 40 | 808 | 61 | 543 | 63 | 149 | 56 | 350 | 45 | 242 | 61 | 198 | 70 | 213 | 59 | 296 | 57 | 317 | 69 | 482 | 44 | 155 | 56 | 802 | 50 | 200 | 56 | 282 | 43 | 573 | 48 | 388 | 52 | 250 | 62 | 396 | 48 | 572 | | | ...

...Qualitative Analysis There is a common tendency among young analysts to disregard all background information on a company and proceed straight towards analyzing financial statements. In this context, it is well worth stating that interpretation of financial statements is aimed at gauging its financial performance or status. Thus, background information is supportive and not decorative. Qualitative factors involved in appraising IDEA are: [pic] [pic] Who are the owners? What is the shareholding pattern? (e.g. Tatas 35%) Major Stake holder is Aditiya Birla Group. Aditya Birla Group has been ranked fourth in the Global Top Companies for Leaders and first in Asia Pacific in the Top Companies for Leaders’ 2011 study conducted by Aon Hewitt, Fortune and the RBL Group. 470 companies worldwide participated in this study. This recognition is personally heartening for me, given that we have competed against the best of breed global companies. |Shareholding Pattern | | |The shareholding pattern of the Company as on | |March 31, 2012 is as follows: | |Category No. of % Share- | % Share-Shares holding | |Promoter and Promoter Group |45.96 | |Foreign Institutional Investors |15.26 ......

...Chapter 1 Introduction to Quantitative Analysis Teaching Suggestions Teaching Suggestion 1.1: Importance of Qualitative Factors. Section 1.2 gives students an overview of quantitative analysis. In this section, a number of qualitative factors, including federal legislation and new technology, are discussed. Students can be asked to discuss other qualitative factors that could have an impact on quantitative analysis. Waiting lines and project planning can be used as examples. Teaching Suggestion 1.2: Discussing Other Quantitative Analysis Problems. Section 1.2 covers an application of the quantitative analysis approach. Students can be asked to describe other problems or areas that could benefit from quantitative analysis. Teaching Suggestion 1.3: Discussing Conflicting Viewpoints. Possible problems in the QA approach are presented in this chapter. A discussion of conflicting viewpoints within the organization can help students understand this problem. For example, how many people should staff a registration desk at a university? Students will want more staff to reduce waiting time, while university administrators will want less staff to save money. A discussion of these types of conflicting viewpoints will help students understand some of the problems of using quantitative analysis. Teaching Suggestion 1.4: Difficulty of Getting Input Data. A major problem in quantitative analysis is getting proper input data. Students can be asked to...

...PJM505 - Quantitative Methods in PJM Technical write up on Software tools available for project management to help managers to use quantitative analysis Project Management: A project is temporary in that it has a defined beginning and end in time, and therefore defined scope and resources. And a project is unique in that it is not a routine operation, but a specific set of operations designed to accomplish a singular goal. So a project team often includes people who don’t usually work together – sometimes from different organizations and across multiple geographies. The development of software for an improved business process, the construction of a building or bridge, the relief effort after a natural disaster, the expansion of sales into a new geographic market — all are projects. And all must be expertly managed to deliver the on-time, on-budget results, learning and integration that organizations need. Project management, then, is the application of knowledge, skills and techniques to execute projects effectively and efficiently. It’s a strategic competency for organizations, enabling them to tie project results to business goals — and thus, better compete in their markets. Microsoft Project has a qualitative risk analysis methodology capability But what about quantitative cost and schedule risk analysis? Quantitative risk analysis gives the project manager the ability to see how a project schedule will be affected......

...BIMS Data Collection Jesse Gillen, Melroy Hyman, Joseph Boots, Michael Richards, Megan Hudspeth QNT/351 February 10th, 2015 Mohammad Sharifzadeh, Ph.D BIMS Research Analysis Introduction This report and the two studies conducted within it are to determine the reason for the increased turnover rate at Ballard Integrated Management Systems, Inc.. This report contains how the studies were conducted, the information that was gathered, interpretations of the data and recommendations for management. Study I Overview Ballard Integrated Management Systems, Inc. (BIMS) is experiencing an increased turnover rate with no clear answer why this is happening. The purpose of this study is to investigate why the turnover rate at BIMS has increased. The question that the research is attempting to answer is: What are the factors that may be contributing to the increased turnover rate in each region? Hypothesis Our hypothesis is that each region is going to show a spike of negative feedback to a specific problem. For example, employees working in the hospitality division may show more displeasure for their supervisor than the employees working in the food service division. This spike may indicate the reason for the increased turnover rate. BIMS One of the problems BIMS faces at its Douglas Medical Center site is a 4 percent increase in employee turnover. The root cause of the increased turnover rate has not yet been determined, and the exit interviews have been......

...Ass Analytical chemistry What is Qualitative Analysis? Qualitative analysis is the aspect of analytical chemistry dealing with the identification of elements or compounds in an unknown substance. Very simply put, it answers the question "What is in this sample?" and usually does so with yes/no question. What is Quantitative Analysis? Quantitative chemical analysis is the aspect of analytical chemistry dealing with determining the quantity of a particular chemical is in a substance. In short, it attempts to answer questions involving "How much?" Accuracy: Accuracy refers to the agreement between experimental data and a known value. You can think of it in terms of a bull’s eye in which the target is hit close to the center, yet the marks in the target aren't necessarily close to each other. Accuracy is defined as, "The ability of a measurement to match the actual value of the quantity being measured". If in reality it is 34.0 F outside and a temperature sensor reads 34.0 F, then than sensor is accurate. Precision Precision refers to how well experimental values agree with each other. If you hit a bull’s-eye precisely, then you are able to hit the same spot on the target each time, even though that spot may be distant from the center. Precision is defined as, "(1) The ability of a measurement to be consistently reproduced" and "(2) The number of significant digits to which a value has been reliably measured". If on several tests the temperature......

...QUANTITATIVE ANALYSIS: DESCRIPTIVE STATISTICS Introduction Suppose that we have carried out a survey on the effect of carrying out a management audit with three groups of nine participant institutions each i.e. small medium and large. Each group was given the same survey questions in questionnaire format and the answers from the scores were tagged between 0 and 20. What is to be done with the raw scores? There are two key types of measures that can be taken whenever we have a set of scores from participants in a given condition. First, there are measures of central tendency, which provide some indication of the size of average or typical scores. Second, there are measures of dispersion, which indicate the extent to which the scores cluster around the average or are spread out. Various measures of central tendency and of dispersion are considered next. For this assignment, a survey is the type of data collection method in consideration and how the results of that survey would be analysed. SURVEYS Surveys are a very popular form of data collection, especially when gathering information from large groups, where standardization is important. Surveys can be constructed in many ways, but they always consist of two components: questions and responses. While sometimes evaluators choose to keep responses “open ended,” i.e., allow respondents to answer in a free flowing narrative form, most often the “close-ended” approach in which respondents are asked to select from a range......

...BUSN311: Quantitative Methods and Analysis The qualitative data used in this analysis broke down the numbers between men and women employees of the American Intellectual Union (AIU). The demographics of men far outweighed the women in this job with 40 men verses the smaller number of 12 women. This particular data was collected to express the number of each gender both male and female employees. The results clearly demonstrate that this profession is heavily dominated by males. This data could potentially identify links in job satisfaction in any given profession. The purpose of this study was to identify contributing factors associated with job satisfaction or dissatisfaction of both male and female employees in the AIU by demographic characteristic (Cano, Miller). Gender Breakdown 40 Males 12 Females Mean 1.230769231 Median 1 Mode 1 Standard Deviation 0.425436 Sample Variance 0.180995 The quantitative methodology used in the study of employees of the American Intellectual Union was intrinsic. Depending on the type of information required for this study, a parameter must use a constant that is most appropriate for the study. In this case, the intrinsic data focused on the level of job satisfaction. The range was from 1-7 with 7 being the highest level of satisfaction and 1 being the least satisfied. The range in this study fell mostly......
