When customers complete surveys it helps to identify areas of strength and also areas of growth. Currently, Harmony Grill is experiencing a decline in customers due to customer service issues. Providing customers with the opportunity to give feedback empowers them by making their thoughts heard and helps the management by using the following consumer feedback to identify customer service issues as the restaurant would like to identify key areas which it could make changes to provide better training to improve customer service for all patrons and create a better dining experience. A sample size consists of the amount of people who will be surveyed. Initially, Harmony Grill decided to use the sample process of 200 people, which consisted of 100 patrons during lunch hours, and 100 during the dinner hours. However, after careful consideration, Team A made the decision to lower the sample size in an effort to receive data based on information retrieved in a short amount of time, as the survey was administered to family and friends of team members via the internet...

...completely related to the needs of a specific project. Qualitative research: Subjective research where the researcher will ask a customer for their opinion or thoughts. Quantitative research: Research that uses a large sample of people to gather statistical information. Sampling: Sampling is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. In business and medical research, sampling is widely used for gathering information about a population. Random sampling: In this technique, each member of the population has an equal chance of being selected as subject. The entire process of sampling is done in a single step with each subject selected independently of the other members of the population. Quota sampling: In quota sampling, a population is first segmented into mutually exclusive sub-groups. Then judgment is used to select the subjects or units from each segment based on a specified proportion. Quota sampling is useful when time is limited, a sampling frame is not available, the research budget is very tight or when detailed accuracy is not important. Stratified sampling: Stratification is the process of dividing members of the...

...Tuggeranong; all people who play the flute. Sample: a set of individuals drawn from a population e.g. the female students in STAT1008 are a sample of all female students at ANU. If we have a population…. We can get parameters – true values for things like the centre and spread of the population We know the answers – what proportion are this tall? We look at the population and get the answer. If we have a sample… We can get statistics – these are values that estimate the parameters e.g. sample centre and sample spread used to estimate population centre and population spread We have to use inference to do this estimation – what proportion are this tall? Based on our sample, we would expect…. 1 So, statistical inference… The process of making an estimate, prediction or decision about a population, based on a sample. Note: populations are generally hard to study – large, awkward! So using samples is much more common Sample or Census Population: all elements sharing some set of characteristics; comprises the universe for the...

...census, less costly to administer than a census and it is possible to obtain statistical results of a sufficiently high precision based on samples. There are two types of sampling techniques, probability and non-probability sampling. Probability Sampling A probability sampling method is any method of sampling that utilizes some form of random selection. In order to have a random selection method, you must set up some process or procedure that assures that the different units in your population have equal probabilities of being chosen. Humans have long practiced various forms of random selection, such as picking a name out of a hat, or choosing the short straw. These days, we tend to use computers as the mechanism for generating random numbers as the basis for random selection. To produce our results, we combine the responses from the sample in a way which takes account of the selection probabilities. Our aim is that, if the sampling were to be repeated many times, the expected value of the results from the repeated samples would be the same as the result we would get if we surveyed the whole population. Because we know the probability of getting each sample we select, we can also calculate a sampling error for the results. The sampling error tells us the amount of variation in the results due to the sampling alone. It gives a measure of the quality of the sample design, and of the survey results. A simple random sample is a sample in which each member of the population...

...critical behavior in research analysis will analyze an ethical issue raised in the article, The Causal Generalization Paradox: The Case of Treatment Outcome Research, written by Graham L. Staines. The article by Staines discusses the causal generalization paradox. The ethical issue at the heart of the article is the use of improper sampling procedures. With the vast amount of research taking place and random assignment techniques, less of a priority is being placed upon random sampling. According to Staines,2008 experimental research typically selects units, in part or in whole, at the convenience of the researcher. The researcher then makes no attempt, or often times only a limited attempt, to ensure that this sample is an accurate representation of some larger group or population. This form of convenience sampling is an ethical issue simply because experimental data based upon the use of “convenience samples rather than probability based samples, there is almost never a formal justification, or set of rigorous guidelines, for generalizing the study’s findings to other populations” (Staines, 2008). The generalization paradox and improper sampling procedures may often cause...

...methodologies usually measure consumer behavior, knowledge, opinions, or attitudes. Such methodologies answer questions related to how much, how often, how many, when, and who” (Cooper & Schindler, 2014), one main quantitative data collection instrument is survey which is considered a major among other ones because it throws exact measures of opinions and consumer behavior. The nature of sampling is “that by selecting some of the elements in a population, we may draw conclusions about the entire population” (Cooper & Schindler, 2014). Some examples of sampling methods available to researchers include: “Purposive sampling where Researchers choose participants arbitrarily for their unique characteristics or their experiences, attitudes, or perceptions; as conceptual or theoretical categories of participants develop during the interviewing process, researchers seek new participants to challenge emerging patterns, Snowball sampling where Participants refer researchers to others who have characteristics, experiences, or attitudes similar to or different from their own and finally Convenience sampling where Researchers select any readily available individuals as participants. Descriptive statistical methods are used to “display characteristics of the location, spread, and shape of a data array, it attempts to describe or define a subject ,often by creating a profile of a group of problems, people, or events, through the collection of data and the tabulation of the frequencies on research...

...Research Methodology Report for the Modular Grants Application Process Outcome Evaluation Study 1. Introduction This report describes the research methodology used for the Modular Grants Application Process Outcome Study. More specifically, this paper is divided into three sections that describe the sampling, data collection, and response rates for the five stakeholder groups involved in the outcome study. The five stakeholder groups are: 1) principal investigators, 2) peer reviewers, 3) NIH scientific review administrators, 4) NIH program and grants management staff, and institutional officials. The first section includes information on the size and origin of the sampling frames (population files), the sample sizes, sampling methods, and margins of error (confidence intervals) around the population estimates. The second section describes the data collection procedures and the last section provides the study response rates and calculations. 2. Sampling 1. Population The size and origin of each of the sampling frames, or population files, is described in detail below. 1. Principal Investigators In March 2004, NIH provided Westat with a population file that consisted of all people who had applied for a modular grant since its inception in June 1999. The population file contained a flag indicating whether or not the individual had ever been awarded a modular grant. The file also contained the principal investigators’ mailing address, telephone number...
