While determining a sample size, the researcher would first need to know how many people, otherwise how many animals would be required because if you do not have enough sample size then it will have an cause on the general study conclusion (2006).
The arithmetical power, P level as well as the treatment including the error variability is the factors otherwise; it would be the parameters in order to aids the researchers with choosing the correct sample size for the study (2006). The arithmetical power informs us how powerful the contributing people otherwise the animals in the study is going to be affected with the treatment that will be given to each of them. The P level will assist the researchers in determining the probability for any variation within the topic throughout the study (2006). At last, the investigators have determined the accurate sample size established as to whether or not the remedy predictability for the study is larger than the error predictability. In which it means that some more participants might be needed for the study if the researchers determine to facilitate the affect of the treatment that would happen to be smaller than the error variability (2006).
Creative researcher systems as well as the raosoft are survey system companies that provides calculators in order to decide the model size intended for the research investigation. However, for a sample size calculators they are accessible through Creative Research Systems in addition to Raosoft in which the Creative Research System company has a field where the assurance interval could be put in, in which it will determine the scope of error for which it is going to happen for supporting on the responds of the research contributors (2010) (2004). Also the calculators preference offers an…...

...Fundamentals of Statistics Jeanna Starr American InterContinental University Abstract A data analysis was done on job satisfaction for the company AIU categorized by age, gender, tenure, position, and department. Overall job satisfaction as well as intrinsic (satisfaction with the actual performance of the job) and extrinsic (office location or work colleagues) job satisfaction were considered in this survey. Introduction AIU assembled a team of researchers to study job satisfaction. I was selected as part of a group to participate in a massive global undertaking. The study required me to examine data and analyze the results. The study consists of job satisfaction, which is extremely important to an organization’s overall success. This particular study will allow managers to gain understanding and knowledge about what type of human behaviors can be used to strengthen an organization’s performance. Chosen Variables I have chosen gender for my qualitative data and intrinsic for my quantitative data. The reason that I have chosen these two variables is because I thought it would be interesting to analyze if males or females were more satisfied with their job, and how the actual job performance reflected their job satisfaction rating. Difference in variable types Qualitative variables include subjects that are non-numerical, such as gender. Quantitative variables include subjects that are numerical and give us a clear visual as to what the......

...Introduction There are five different data collection methods, using articles I will provide two different examples of data collection. Body             Using an interview to gather data can be a successful way to get the information you need. You can base your interview questions solely on the information you need and want and nothing more. One way to collect information that can be an easy way to gather information that you need with would be to ask close ended questions, with a yes or no answer. This way you can get the information you need and want and not have a lot of excess information that is not needed.            Another way to collect data would be to observe people. You can gather data by observing for multiple things. Clothing styles, colors, hair styles and things of that sort. When observing people to gather data, you need to make sure that you are in a place that has a wide variety of people. If you are observing people in a gym then you will most likely find people in sporting wear rather than wearing jeans. When in a children’s store you may find expectant mothers, grandmothers, young couples, older couples, a wide variety of people. Another place you would find a wide variety of people to observe is a grocery store or big box store.             There are advantages and disadvantages to using each method for collection of data. A few advantages would be that the information relates solely on what is currently happening within that situation. Whoever......

Chosen Variables The variables qualitative which are Boys between the ages of 13- 17, and Quantitative showing how behavior in the home. I choose this because I work with children at our church and notice that boys this age are less involved in activities than girls. Difference in variable types The difference between qualitative and quantitative variables are Qualitative variables are non numeric which means I can discuss the gender of a person. Quantitative variables are numeric which means I can discuss age, height and weight. They have to be used differently because they don’t relate the same way.

...Quantitative Methods and Analysis Unit 1 DB Leonidas Murembya July 22, 2013 My first choice is the face-to-face data collection method.The population health surveys trend to rely on five main methods of data collection, the one that I am doing is the Face-to-Face interview. Most of them in this study chose to do the face-to-face interview. The face-to-face is also known as FTF. The face-to-face interview method was done on the Population Surveys of Children’s Health and Wellbeing: Parental Views on Data Collection Content and Methods. (Waters, E., Davis, E (Nee Maher) & Mehmet-Radji, O., 2005-206). The face-to-face interview method could be done one on one or in a group setting. This study had been done on a group from Australian families with the children ranging from zero to twelve years of age. The face-to-face interview method is on their health status in which it has four subgroups for it, one is the health and wellbeing, the second one is the growth and development, third one is the mortality, the fourth one is morbidity and disability, as well as the fifth one is the safety and security. However, other professionals, such as doctors, do other studies and then there are also other kinds of face-to-face interview methods as well depending on what they are looking for in the child. There are several pros and cons for a face-to-face interview method. The cons would be that you would have a variety of communication (technology) (Editorial Board 2012). Then you......

Over a three week (21-day) scheduling period, each unit will be scheduled for seven days. Normal staffing requires 186 firefighters to be on duty every day. Thus, each unit needs to provide staffing for 7*186=1302 firefighter days. During a three week period, each firefighter provides 6 days of service. Therefore, Base no of firefighters needed by each unit=1302/6 = 217 Base no of firefighters needed by each unit=217. 2.

...Question 1: After consider the requirements, we decide to use Mean-Variance preferences method to calculate the utility we can get from investing four stocks: DBS, SPH, GE, SIA. We know the equation: Ur= μ-γ2 Varri=μ- γ2σi2 We can decide weight of four stocks by maximizing the utility of the portfolio. (N=4, T=232) So we suppose: 1. The best portfolio is the one that satisfy owner most, which means have the maxi utility. 2. The owner is afraid of risk, and the risk aversion is measured by γ, γ=3 3. The portfolio will be hold for one year. From equation: Rate=R1-R2R1 We can get return rates of four stocks in different periods since Jan-96 (See sheet 1), and the mean return rates μ for the four stocks are: DBS=0.10814638, SPH=0.0733264, GE=0.12002196, SIA=0.06982988 And we can get the Covariance Matrix: 0.105279399 0.041817263 0.05022109 0.0565126810.041817263 0.062596535 0.025656805 0.0373403140.05022109 0.025656805 0.109059667 0.0386166250.056512681 0.037340314 0.038616625 0.065556537 A= 21.372.

Approximately 1,500 adults participated nationwide and has a marginal error of +3%. This survey could be used to evaluate how a person views different situations. By providing more information, an individual can learn if two people who live or work in the same area share the same views on their surroundings (Gallup, 2008). Also a company can use the information gathered in this survey and compare it to previous surveys pertaining the same questions and decide if economics or events in the world, such as war, played a direct affect on how people view their lives. Conclusion: The three surveys that were investigated each included a large demographic area but had few responses. So the information obtained within these surveys cannot be deemed as scientifically accurate. The one survey that does include information that you can use to further research results is the Life Evaluation done by Gallup. This particular survey included a margin of error that would allow for a research to add votes for a more definitive follow up survey.

...Jet Copies Case Problem Alex B. Wilson Professor Henry Grimm Quantitative Methods-MAT 540 February 12, 2012 Strayer University-Allentown Campus Jet Copies Case Problem 1 If you assume that the number of days needed to repair a copier is random, you can generate a random number using the Excel RAND function which I denoted r2 between 0 and 1. If 0 < r2 < 0.2 then it takes 1 day 0.2 < r2 < 0.65 then it takes 2 days 0.65 < r2 < 0.90 then it takes 3 days 0.9 < r2 < 1 then it takes 4 days 2 The probability distribution of the random variable varies between the times of 0 to 6 weeks, with the probability increasing as time goes on. This can be approximated by the function f(x) = x/18 for 0 < x < 6 Therefore, the distribution function is f(x) = x-square divided by 36 for 0 < x < 6 If we set this equal to another random number r1 that is between 0 and 1 then R1 = x-square divided by 36 which results to x = 6√ r1 3 Since the number of copies sold per day is a uniform probability distribution between 2000 to 8000 copies, I made r3 a random number between 2000 to 8000. To get the amount of business lost on a particular day, I take r3 X (repair time), and the lost revenue is then equal to 0.1 X r3 X repair time, since they charge $0.10 per copy. 4 After running the simulation, I got the following results: Repair Distribution P(x) | Cumulative | Repair time | 0.2 | 0.000 | 1.000 | 0.45 |......

Part A is worth 50% of the marks, and Part B is worth the remaining 50%. Your report for the two parts should consist of no more than 1,500 words. Part A – Blanket Systems Blanket Systems is developing and testing a new computer workstation, OB1, which it will introduce to the market in the next 6 months. OB1 will be sold under a three-year warranty covering parts and labour. The company has decided to subcontract the service support for the warranty and has entered negotiations about the support contract with Fixit Inc. Fixit has proposed two different pricing schemes for the subcontract. The first involves the payment of a fixed fee of $1,000,000 and the second a variable fee of $250 per workstation sold, subject to a minimum fee of $350,000. Under both schemes, the payment will be made one year after the introduction of the workstation to the market at which point the product will be replaced by newer models not covered by the warranty service subcontract. At the moment, there is uncertainty about the sales potential of the new workstation. Sales of OB1 are expected to come from two sources: (i) the successful closure by senior management of a major purchase of 2000 units by a long standing customer, (ii) the efforts of regional sales offices. Given the state of the negotiations with the long-standing customer, the current estimate......
