...1.12 What is the difference between a sample and a population? In most studies, it is difficult to obtain information from the entire population. We rely on samples to make estimates or inferences related to the population. Population means the population of the whole area. Sample means a sample of people taken out of the population to be tested or studied. 1.13 What is the difference between a statistic and parameter? The difference between parameter and a statistic is that a parameter is a number obtained by calculation from a population while statistic is a number calculated from a sample. A statistic is usually used to estimate a parameter. 1.22 A Gallup poll indicated that 74% of Americans who had yet to retire look to retirement accounts as major funding sources when they retire. Interestingly, 40% also said that they looked to stocks or stock market mutual fund investments as major funding sources when they retire. (data extracted from D.Jacobs, “Investors Look Beyond Social Security to Fund Retirement,” www.gallup.com, March 28, 2011). The results are based on telephone interviews conducted March 24, 2011, with 1,000 or more adults living in the United States, aged 18 and older. a. Describe the population of interest. They are the Americans that have not retire yet. b. Describe the sample that was collected. They are the 18 and older group of adults. c. Is 74% a parameter or a statistic? Explain.

...size of research population, it is not feasible to test all the individuals of the population since it will take too much time and will be expensive as well. So the researchers take few individuals from the research population ( a subset of the set of target population) using sampling techniques. These techniques helps to take out sample as per the requirements of the type of research that is to be conducted. A research population is also known as a well-defined collection of individuals or objects known to have similar characteristics. All individuals or objects within a certain population usually have a common, binding characteristic or trait. Usually, the description of the population and the common binding characteristic of its members are the same. "Government officials" is a well-defined group of individuals which can be considered as a population and all the members of this population are indeed officials of the government. There are various sources from which a sample is created. A set of all these sources is called a Sampling frame from which the sample is selected. With the help of sampling frames, researchers are able to select the sample population from the target population that will be tested for the research or survey. A sampling frame should have the following characteristics: Completeness: A frame should be complete in a sense that all the individuals of the target population should be covered in the frame. In case we are...

...Chapter 1: Introduction 1.1 Background “3G, short for third Generation, is the third generation of mobile telecommunications technology” (Geneva, 2002). 3G telecommunication networks support services that provide an information transfer rate of at least 200 kbit/s. Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smart phones and mobile modems in laptop computers. “3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. This is a set of standards used for mobile devices and mobile telecommunication use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV” (Smith and Collins, 2000). 3G technology is the result of research and development work carried out by the International Telecommunication Union (ITU) in the early 1980s. 3G specifications and standards were developed in fifteen years. The technical specifications were made available to the public under the name IMT-2000. “The communication spectrum between 400 MHz to 3 GHz was allocated for 3G. Both the government and communication companies approved the 3G standard” (CDG Market Trends and Facts). “The first pre-commercial...

...CHAPTER 3 RESEARCH METHODOLOGY This chapter presents the method of research utilized in the study, the population, sample size, and sampling technique, description of the respondents, research instrument, data-gathering procedure, and statistical treatment used for data analysis. Research Method Used The descriptive method of educational research was employed in the study, since it describes what traits or what it is of a certain educational phenomenon. Borg defines the descriptive method as a distinctive research methodology of systematic data collection, presentation, and analysis. The method of research is concerned with conditions and relations that exist, practices that prevail, processes that are going on, point of view effects that are being felt, or trends that are developing. This method is the most appropriate method for this study, as Best asserts that the descriptive research goes beyond mere tabulation of data to the analysis and interpretation and meaning of what is being described. It involves a more in depth analysis through the use of numerical and comparative analysis.

...Learning Outcome Four 1.3 reasons make samples rather than a census while going surveys: (1) Accurate (with appropriate sample size and efficient sampling method) Sampling can be more accurate than a census as there is greater control of interviewers and less chances of mistakes being made as the data is collated. (2) Economy (save money) Unit cost of collecting data in the case of census is significantly less than in the case of sampling, for example: In case of census is taken 300, while in the case of sampling is taken 2,000. But due to the larger number of items the total cost involved in the case of census is significantly higher than in the case of sampling. (3)Save time A simple may provide you with needed information quickly. For example, you are a Doctor and a disease has broken out in a village within your area of jurisdiction, the disease is contagious and it is killing within hours nobody knows what it is. You are required to conduct quick tests to help save the situation. If you try a census of those affected, they may be long dead when you arrive with your results. In such a case just a few of those already infected could be used to provide the required information. 2. The difference between sampling and non-sampling errors: Sampling errors reflects the differences due to chance. There are two ways may cause sampling errors. First one is called “The margin of error”, which is happened by Choosing the different sample. The result, sometimes, will be different...

Is this a population or a sample; explain your answer. The randomly selected group of 500 patients with high cholesterol is a population. 67% of that population has heart disease. It is considered a population because it is the entire group of patients that in which we are interested, and desire to draw a conclusion on heart health. The blood sample drawn to determine high cholesterol might be a sample under this study. b) An investigation of 150 randomly selected local restaurants concluded that 42% of local restaurants have serious health code violations. Is this a population or a sample; explain your answer. This is also a population. A population is an entire collection of people, animal, plants, or things from which we want to draw a conclusion. In this case, the things (restaurants) are the population which is being studied for health code violations. Scores on inspections, and other gathered data, may be considered a sample based on the tests. 2) Determine whether the given value is a statistic or a parameter. a) A researcher determines that 42.7% of all downtown office buildings have ventilation problems.

...after the participants agreed to participate in this research. Participants were given 10-15 minutes to complete the questionnaires. Researchers collected back the questionnaires right after participants completed it. Participants are not allowed to change any of the answers after the submission of questionnaire. The process of this data collection took 2 days. It started from 17th January 2014 to 18th January 2014. HOW TO GET SAMPLE The population of this research is UTAR, Perak Campus students. While our sample is 50 undergraduate students from Faculty of Arts and Social (FAS). These 50 students were divided into 2 groups according to gender which is male and female. Therefore, our sample was 25 male students and 25 female students from FAS. We got this sampling method through random sampling method. Random sampling means every member of the population have an equal chance of being selected. Our sample is said to be an unbiased sample because the sample is chosen at random from the population. We used ‘coin toss’ method to randomly select our sample. The results are based on the coin side produced upon tossed. If the result is the head of the coin,...

...BES Tutorial Sample Solutions, S1/13 WEEK 2 TUTORIAL EXERCISES (To be discussed in the week starting March 11) 1. What is meant by a variable in a statistical sense? Distinguish between qualitative and quantitative statistical variables, and between continuous and discrete variables. Give examples. A variable in a statistical sense is just some characteristic of an ‘object’. It may take different values. Data on a quantitative variable can be expressed numerically in a meaningful way (e.g. height of an individual, number of children in a family. Data on qualitative variables cannot be expressed numerically in a meaningful way; e.g. sex of an individual, hair colour). A discrete quantitative variable can assume only certain discrete numerical values on the number line (can be a finite or infinite number of these values). A continuous quantitative variable can assume any value in a specific range or interval; e.g. length of a pipe. 2. Distinguish between (a) a statistical population and a sample; (b) a parameter and a statistic. Give examples. A statistical population is the set of measurements or observations of a characteristic of interest for all elementary units in a frame; e.g the shoe sizes of all men in Australia. A statistical sample is a subset of a population; e.g. the shoe sizes of all the men in the class 1 is a sample of the population represented by the shoe sizes of all men in Australia. A parameter is a numerical description of a population. For example...

...Perception of College of Arts and Sciences Freshmen Students Towards Math 2 Subject Introduction Mathematics is an essential subject that is part of the curriculum. Through this, we learn how to count, to solve and to analyze problems involving numbers. The application of Mathematics is in our daily life. Learning Math should not be neglected because it will be our foundation in our future career. Understanding Math in a deeper way is quite difficult, that is why it is not new to us to hear different comments about this subject. It will always depend on how we are going to handle ourselves towards this course. Students are of different traits and personalities while learning. Some students would just go to school to have the feeling of belongingness not even minding the education that they could get. There are also students that are doing great in school and giving the best of them for their parents. As we have notice, almost of the students don’t really have the interest in studying Mathematics. They find it hard, tedious, and boring because it involves lots of equations and functions to solve. It is true, you can never learn Math unless you will have the application on this. It is not just merely counting, solving and analyzing. Math is a broad subject and we cannot learn all this in just 4 years of studying in college. The students should know the significance in learning the basis in Mathematics. To make this interesting we should know the purpose of why we should love...
