...DQ 1, Week 2 of HLT-362V Explain the importance of random sampling. What problems/limitations could prevent a truly random sampling and how can they be prevented? The importance of random sampling is the use of statistically derived random sampling processes. These ensure that survey results can be fortified as statistically illustrative of the population. Surveys that do not follow these procedures can yield results that lead to misguided market research, strategic, or policy decisions. Any survey in which no attempt is made to randomly select respondents, such as in polls, is likely to produce results that in no way reveal general public opinion. Even if many thousands of individuals participate. It is true that sampling randomly will eliminate systematic bias. The mathematical theorems which validate most frequent statistical procedures relate only to random samples. The problems/limitations that could prevent a truly random sampling are important because it assures that the conclusions you draw can be applied to your entire population. The subsequent issues that could cause problems with random sampling are if the experimenter selects a sample that is too small and the experimenter does not understand the population. This can be prevented by using the standard deviation which, is divided by the square-root of the sample number (n), which means that the standard error will be smaller than the population standard deviation, and that it will get progressively smaller as...

...ω(q): fω (x) = ln(10) 10(x+ΥMP, dB )/10 fΥMP 10(x+ΥMP, dB )/10 . 10 Some experimental measurements have also suggested Gaussian to be a good enough yet simple fit for the distribution of ω(q) [17]. We will take advantage of this Gaussian simplification later in our framework. As for the shadowing variable, log-normal is shown to be a good match for the distribution of ΥSH (q). Then, we have the following zero-mean Gaussian pdf 2 1 for the distribution of ν(q): fν (x) = √2πα e−x /2α , where α is the variance of the shadowing variations around path loss. Characterizing the spatial correlation of ω(q) and ν(q) is also considerably important for our model-based channel prediction framework. However, we do not attempt to predict the multipath component, ω(q), due to the fact that it typically decorrelates fast and that the form of its correlation function can change considerably, depending on the angle of arrival and position of the scatterers. Therefore, in our proposed framework we only predict the path loss and shadowing components of the channel. The impact of multipath will then appear in the characterization of the prediction error variance, as we shall see. As for the spatial correlation of shadowing, [18] characterizes an exponentially-decaying spatial correlation function, which is widely used: E ν(q1 )ν(q2 ) = α e− q1 −q2 /β , for q1 , q2 ∈ K where α denotes the shadowing power and the correlation distance, β, controls the spatial correlation of the channel [18]. For some examples...

...603 Business Research Methods Assignment 1 Submission date: 16/05/2015 Submitted By: Rajinder Singh Student Id: 1502A487 Answer no . (1.1) In this scenario, owner of an Italian restaurant wants to introduce a new pasta dish. James, a business research executive hired by the restaurant owner Pablo has to conduct a research with the customers to find out reaction about the dish. James has proposed a face to face interview technique to Pablo for this research work. Face to face interview is a one on one interview, where both interviewer and interviewee sits together to get some useful information. There are many types of interviews like telephonic interview, using internet chat etc. but according to me best suitable type of interview that can help Pablo to get his needed information is Face to Face interview. Below are some key attributes of a Face to Face interview those are best suitable to get information that Pablo is looking for. 1) Time and Place – Time and place of the interview is very important. To conduct an effective interview it is very important that you should aware about, what time and date is the best to conduct an interview. For example in this case, by conducting interview on weekends you might get better results as compared to weekdays like Monday where there are less people visiting the restaurant or they can be busy in their work. On the other side the place you are going to choose for the interview is also very important. For example in this...

...QNT-351 Discussion Question Responses * DQ#1: What is the importance of statistics in business decision making? Describe a business situation where statistics was used in making a decision. 1. Using statistics to evaluate the performance of your business. Taking all factors into account, determine whether you are making or losing money. In addition, determine the trend of your business. For example, determine whether, over time, you are making more or less profit (or loss). Track the share of the market that your business holds, and how this changes over time. Evaluate all these factors for each product type, even each model, in your company's line. The statistics to use here are simple line and bar graphs of data. These data can alert you to where you need to change aspects of your business, and how quickly you have to make that change. Furthermore, statistics are an excellent way to determine how you should allocate your resources to increase sales. Sales in a given market are a result of a number of factors, such as pricing, the size of the sales force, and the type and number of advertisements placed. However, these factors will not be equally important for every product. You would use multiple regressions to determine which of these factors are most important, and how much changing your asset allocation (for example, the size of the sales force) will change sales. 2. Statistics: The science of collecting, organizing, and analyzing data. Descriptive Statistics...

...UNIT #5 DISCUSSION DQ #1: Data collection is one of the most challenging steps that prevent learners from completing their dissertation. What challenges do you foresee in collecting your data? What are some strategies you’ll deploy to overcome these challenges? a) Challenges in collecting data Reliability and validity In data collection, reliability and validity of the data are important considerations, which a researcher should pay attention to. Reliability, in this case, can be described as the degree to which the data collection process is consistent. On the other hand, validity arises when variables measure what they were intended to measure. And, this, usually, happens when the data collection process has been reliable. Data collection form Construction of a data collection form is one of the important considerations that every researcher should consider, before the inception of the data collection process. Designing the form requires that a researcher pay a lot of attention to all the established variables, from the topic. If all variables in the research are not covered in the form, it might not be possible to get complete information to enable well informed conclusions from the data analysis. The wording of the form is also very important. If the form is not carefully worded, it might bias the participants’ responses. The questions should also be impersonal to encourage open and honest responses. In the absence of this, it is likely that the full story would...

...The Learning styles of Students in St. Michael’s College INTRODUCTION The term “learning styles” speaks to the understanding that every student learns differently. Technically, an individual’s learning style refers to the preferential way in which the student absorbs processes, comprehends and retains information. For example, when learning how to build a clock, some students understand the process by following verbal instructions, while others have to physically manipulate the clock themselves. This notion of individualized learning styles has gained widespread recognition in education theory and classroom management strategy. Individual learning styles depend on cognitive, emotional and environmental factors, as well as one’s prior experience. In other words: everyone’s different. It is important for educators to understand the differences in their students’ learning styles, so that they can implement best practice strategies into their daily activities, curriculum and assessments. The setting of learning objectives in a lesson provide opportunities to focus on and revisit the learning objective through approaches such as questioning, peer and self-assessment, written and oral feedback. It is important for us all to recognize that there are many ways to give learning objectives to students and also to re-visit them when appropriate. The aim of this study of the toolkit is to give ideas for some different approaches. METHODS Research Design This research is entitled “The...

...Research is the systematic investigation into existing or new knowledge.[citation needed] It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field. In order to test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects, or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation,discovery, interpretation, or the research and development of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences.
