I will call life which is required to be exchanged for it, immediately or in the long run” (29). Therefore, he echoes the argument that money, or items purchased, can only be measured in the time given up to acquire them. However, while living a simple life, materialistic items have less value over time. Inner peace and freedom carry a greater merit, which enables humanity to enjoy spiritual…

1950s. Edie, who is the main character of the story, is a live in housekeeper for the Peebles.

selecting a wrong sample design. The size of the sample must be in a certain criteria such as precision level, confidence level, and the variability degree. In the case of sampling the attitudes of Bank of America customers and their decision to withdraw their accounts from the bank or not can be accomplished by sampling several states across the country. Determining the sample size is very important, it may vary from one to another. In work environment knowing about the sample size before…

Strategy and Sample Size for a Quantitative Research Plan Introduction When a researcher is constructing a sampling method, the questions about the population where the sample will come from and the size of the sample to be used come into play for the purpose of seeking statistical validity (Frankfort-Nachmias & Nachmias, 2008). Parahoo (2014) explains that, in order for sampling method or strategy to be considered credible, defining the population to be sampled, type of sampling, sample size,…

insight on the ways in which sleep quality influences quality of life of undergraduate students at OU. Sample Frame, Population The sampling frame is undergraduate students enrolled at the University of Oklahoma. The list of components, from which the sample is designated, was formed through careful consideration…

and Uzunboylu used the stratified random sampling method. The teacher sample was made up of 25% of the total number. The student sample was made up of 9% of the target population. The qualitative authors decided to use the criterion sampling strategy. The teachers that were selected had to meet the criterion of using MCDs or taught students that uses MCDs such as, cell phones, smart phones, or tablet computer for teaching or learning. The quantitative sample used stratified sampling which is…

Quantitative risk analysis is the one which follows the Qualitative analysis, and gives a numerical priority rating to project risks (PMI, 2009). Based on the PMBOK (PMI, 2013) quantitative risk analysis “… is the process of numerically analyzing the effect of identified risks on overall project objectives (p. 333).” This is also a process for the PM and project team to get risk data to support making decisions, which can help to reduce project uncertainties (PMI, 2013, p. 333). Based on the…

aspect of evaluating credit derivatives, the copula function has gradually become the main approach in pricing CDO (Burtschell & George, 2005). In Li (2000) paper, a new random variable named ‘time-until-default’ was created to demonstrate survival time of each defaultable entity. And the copula function approach is based on this random variable to evaluate the default probability of financial instruments. Specifically, copula function specify the joint distribution of the survival times after…

precise, as the average weight difference is identical to that of the weight difference caused the glucose solution. Low levels of precision can be accounted for by random errors. Random errors are errors caused my unpredictable factors such as wind change or a mistake in the method. In this experiment, there are many possible sources of random errors that may have influenced the results and these may have…
