1. DIFFERENTIATE DESCRIPTIVE STATISTICS FROM INFERENTIAL STATISTICS. ANSWER:

The difference between Descriptive Statistics and Inferential Statistics:

Descriptive Statistics includes statistical procedures that we use to describe the population we are studying. The data could be collected from either a sample or a population, but the results help us organize and describe data. I can only be used to describe the group that is being studying. That is, the results cannot be generalized to any larger group; while,
Inferential Statistics is concerned with making predictions or inferences about a population from observations and analysis of a sample. That is, we can take the results of an analysis using a sample and can generalize it to the larger population that the sample represents. In order to do this, however, it is imperative that the sample is representative of the group to which it is being generalized.

2. DIFFERENTIATE PROBABILITY SAMPLING FROM NON-PROBABILITY SAMPLING.

The difference between Probability Sampling and Non-Probability Sampling:

Probability Sampling are selected in such a way as to be representative of the population. They provide the most valid or credible results because they reflect the characteristics of the population from which they are selected (e.g., residents of a particular community, students at an elementary school, etc.); unlike,
Non-Probability Sampling are less desirable than probability samples. However, they are limited with regard to generalization. Because they do not truly represent a population, we cannot make valid inferences about the larger group from which they are drawn. Validity can be increased by approximating random selection as much as possible, and making every attempt to avoid introducing bias into sample selection.

...Methodologies Compare and contrast between qualitative and quantitative research methodologies. How would you apply each type of research methodology at work? Qualitative research methodology is conducted on site or location of the study where the data are collected, with the research as the key instrument. Instead of numbers, words and pictures such as transcripts of in-depth interviews, field notes, photographs, tapes, memos, personal documents, and other official records are used to collect data. The process from beginning to end or history is more important in this type of method than the outcome of what happened. Information or data collected are not to be approved or disapproved by hypothesis, but are gathered then separated into groups for further evaluation. Why people do the things they do is very important to researchers in the qualitative method, they are concerned with how different people/culture live their lives and make sense of them by looking for common ground. Quantitative research methodology on the other hand, is conducted to ensure objectivity, generalizability and reliability, by testing, retesting and post testing subjects of the study for effectiveness. It relies mostly on numbers, counts, measures, operational values, quantifiable coding, quantitative data and statistical data. Its’ audience is much broader and generalized than that of the qualitative method and investigators would usually go into a study with predetermined questions; methods...

...rate of forgetting. But it is not enough simply to repeat words, or to re-encounter them in their contexts. Much better is to recycle them in different ways. Research suggests that if learners see or use a word in a way different from the way they first met it, then better learning is achieved. 1.6 What makes a word difficult? Learning the words of a foreign language is not an easy business since every word has its form, meaning, and usage and each of these aspects of the word may have its form (daughter, busy, bury, woman, women) and easy in usage; other words are easy in form (enter, get, happen) and difficult in usage. Consequently, words may be classified according to the difficulties pupils find in assimilation. In methodology some attempts have been made to approach the problem. The analysis of the words within the foreign language allows us to distinguish the following groups of words: concrete, abstract, and structural. Words denoting concrete things (book, street, sky), actions (walk, dance, read), and qualities (long, big, good) are easier to learn than words denoting abstract notions (world, home, believe, promise, honest). Structural words are the most difficult for Russian-speaking pupils. In teaching pupils a foreign language the teacher should bear this in mind when preparing for the vocabulary work during the lesson. 1.7 Psychological and linguistic factors which determine the process of teaching vocabulary Words are elements of the......

... The questions in the survey are comprised of different types of questions such as closed ended, open ended and liker-scale questions that provides greater accuracy on the different aspects that should be tackled in each question. The questions are also created after doing research on finding out the problems or issue that are currently the most prominent when talking about unemployment so that the information gained from the survey would be of great help to access the main problem. The survey is conducted in a shopping mall, specifically in Sunway Pyramid, where a wider scope of audience can be reached. The surveys were then handed out to 10 random people that have graduated or are going to graduate from their higher education. This methodology is very reliable as it is made sure that the people who had completed this survey only consists of graduates or people that are in their final year in university and are going to face this situation of unemployment very soon, showing a result that is more 'true' to the current situation. Also, as different types of questions were used for different questions, a greater accuracy of the public's opinion could be obtained. Lastly, the survey questions were created after doing tons of research so that the biggest problem in this issue could be addressed within the questions that the people answered....

...of a project management methodology. The importance and need for the company to establish an enterprise project management methodology (EPM) was not new to the executives and instead, the year before they chose their ego, power and control over doing the right thing for the company, its clients and ability to win new business from its competitors. Was the executives’ initial approach the best? In all fairness, it is not easy for a company to change its approach of doing business, adapt to changes, and willingly accept a process that is still evolving and that for many has a negative connotation of evading a company’s control. It is the lack of knowledge and understanding of the enterprise project management methodology (EPM) that affected the company’s opportunity for growth and the identification of possible processes and documents that could have been changed or eliminated. The fact that the executives waited so long means that they did not have a mature and strong project management process and corporate culture that fosters communication, teamwork, cooperation, and trust. Each of the executives felt threatened that by developing a methodology, it will have impact to their functional units and their importance omitted or diminished. That is evident based because John Compton had to get involved to coach and led his executives to whom he had entrusted. There is a key difference between project management and a project management methodology – they are not the......

...CHAPTER III METHODOLOGY This chapter outlined the entire research plan. It described how the study was done, the data, instruments utilized, how samples were selected and the analysis of the data using statistical treatment. Research Design The researchers used the true experimental design. It further used Solomon’s Four Group design which involves two experimental groups and two controlled groups. One experimental group and one control group are administered the pretest and the other groups are not, thereby allowing the effects of the pretest measure and intervention to be segregated. In this study there were two groups who were studied: a group who studies alone and a group who studies with a group, this design is a combination of pretest and post test controlled group design, and the post test only controlled group design, in addition to the basic pretest/treat/posttest design three additional test, one without treatment, one without pretest, and one without both pretest and treatment were considered. For a reliable result several sets of four tests were applied and the means used. The various combinations of tested and untested groups with treatment and controlled groups allow the researchers to ensure that confounding variables and extraneous factors have not influenced the results. | |Pre-test |Treatment |Post test | |Experimental with pre-test |O1 |X ......

...METHODOLOGY A. RESEARCH APPROACH This research consists of a survey, considered a quantitative strategy an approach that “that provides a quantitative or numeric descript of trends, attitudes, or opinions of a population by studying a sample of the population” (Creswell, 2009, p. 12). This study will involve a questionnaire, used like a structured interview for collecting data to assist with answering the three research questions; and intended to generalize a sample population of five NGOs (Babbie, 1990 cited in Creswell, 2009, p. 12). B. CHARACTERISTICS OF RESEARCH APPROACH The characteristics of case study research embody the following (derived from Creswell, 2009, p. 175-176): multiple sources of data; theoretical lens; and participant meaning.. First, multiple sources of data may include: observation, case studies related to humanitarian organizations, documentation from humanitarian organization’s source to donors, and other mass media and social media available. Additionally, the study will use framing theory as its guiding approach and how it relates to soft power theory, to understand how humanitarian organizations develop their messages. Finally, the participant meaning by reviewing the responses NGOs have toward the research questions to view “the meaning that the participants hold about the problem or issue, not the meaning that the reaserchers bring to the research or writers express in the literature”(Creswell, 2009, p. 176).
