a) Random sampling is where each element of a given population has equal chances of being included in the sample since the sampjle is picked arbitrarily. Once the sampling frame is identified, the researcher uses a table of random numbers to select the sample or through computer generated numbers. The main advantage of random sampling is that the same is a representative of the entire population. It also eliminates researcher bias. Besides, it allows for application of inferential statistics. The main disadvantage of random sampling are that it is complex. b) It is primary data and not secondary data ...

Question 1

a) Random sampling is a method of sampling in which each member of a population has equal chances of being included into the sample. Each member of the sample is chosen entirely by chance. Since each member has equal chances, one advantage of the random sampling method is that it is fair and unbiased. The random sample chosen can properly represent the population it is taken from. One disadvantage of random sampling is that there is no systematic approach in choosing the sample. If the population being studied becomes larger, the fairness of the random sampling method becomes more ...

The study will use a quantitative research design. A quantitative research design allows for a faster collection of data compared to a qualitative design. It is also suitable for studying large population because it allows the researcher to use inferential statistics (Rubin, 2012). Therefore, the findings from a sample can be used to generalize information about the whole population. This study seeks to assess whether the high prices that Starbucks charges for its coffee drive consumers to its competitors. Therefore, the study is interested in all consumers of coffee at Starbucks. The population of interest is large. A survey ...

D Q. 14-6 It will largely depend on what the research intends to achieve. For instance, supposing the intention of data collection gathers ideas behind patronizing certain types of music, and there are no intentions to conduct inferential analysis on the data, heterogeneous sampling will be appropriate. Some of the techniques that can be used in heterogeneous sampling include conducting panel sessions, plain group discussions or brainstorming sessions (Collis, & Hussey, 2013). On the other hand, if the data collection exercise intends to investigate the reason as to why certain types of music are favored by a larger percentage of ...

Method Description

A quasi-experimental research design will be employed. The nature of the treatment variable (gender) cannot be manipulated by the researcher. However, from the nature of the study, we can deduce a naturally occurring control group (adult-sibling pairs with different gender) and a treatment group (adult-sibling pairs with the same gender). Therefore, a non-equivalent posttest cross-sectional design will be used. A survey method will be implemented by the use of a questionnaire. Data will be collected using a questionnaire because it is time-saving as the data collection will go on concurrently. It is also cheaper than conducting interviews both in ...

Question 1: Describe the sampling strategy. How appropriate were the various sampling design decisions. Answer: The mail survey was distributed to 1650 country club members belonging to a variety of demographic categories (Schindler, 2001). One of the most important considerations in any survey is sample size. 1650 members is a decent size to represent the population of thousands of members associated with the club with a minute margin of error. The collected data can easily be analyzed on 95% to 99% confidence interval with such large size of sample population (Barlett, Kotrlik, & Higgins, n.d.). Then, it is also worth ...

Introduction

Perinatal depression is increasingly becoming a worldwide mental illness that affects expectant mothers. Although depression has always been categorized by world Health Organization (WHO) as a silent killer disease, perinatal depression continue to attract more attention due to its adverse effect on an entire family support system. It puts both the health of the mother, unborn baby, and the newly born at risk, and this risk is gradually transmitted to other family members who are taking care of them. More disheartening is the fact that this disease is more prevalence among the low-income mothers and those in the underserved ...

Study Population

Study population refers to the cumulative subjects to which the research problem is embedded (Creswell, 2014). In this regard, the research study will be inclined to source information from the Saudi Arabian and Iranian countries, to gauge the cause and impact of conflicts that have ruled the land for such a long time. Therefore, the study population will be concentrated on citizens of Saudi Arabia, as well as citizens from Iran. However, it will be unpractical and costly to obtain information from the entire population, and the ordeal gives rise to the need to draw a suitable research sample, ...

The simple random sampling would ensure a high level of representativeness; but it is time consuming and tedious, since every person in the target would have an equal chance of getting selected. Cluster sampling, on the other hand, would be easy and convenient because every person in the target population would be willing to take part in the activity (University of Hawaii, 2001, p.1). However, it is possible that the members would be different from one another and would have no association, which would lessen the technique’s effectiveness. Researchers select a target population when using sampling strategy depending ...

Abstract

Games that are created for purposes other than entertainment are called serious games. The art of applying games on a day to day actions is known as gamification. The gaming elements in serious games can be utilized to simulate reality in teaching and training environments (Crookall 2010, p. 898). Deep learning is a new approach to education and disregards the traditional method where the teacher was the all-knowing authority who passed down facts to the students (Fullan and Langworthy 2014). The traditional method did not view the learning environment as a factor that could affect the learning process. Adult ...

Techniques used when doing quantitative research are not the only way of telling the validity of findings. This is because some of the quantitative researches are likely to be inappropriate. The reason behind this is that in quantitative research assumptions are made that social research science is valid if based on ;experimental data ,official statistics, operational definitions of variables and random sampling. This assumptions have many defects .for example an exclusion of the behavior observation in everyday life .quantification is at times useful as it reveals social processes that are basic. There are some areas of social reality that ...

The society today is facing a rather disquieting series of developments affecting practical academic life in the contemporary society. Arguably, these developments risk degrading the pivotal role of cognitive endeavor or reasoned evaluative criticism in achieving, maintaining, and enhancing of good social justice program in the society. It is hard to simply educate on methods and means of doing evaluation; it is vital to convey the idea of evaluation as realistic, intellectual outlook and disposition on social and political platform. Overall, there is a pressing necessity to learn the need of humanistic evaluation in the social Justice programs. According to Geoff ...

Introduction

Sampling is a more convenient way of identifying and picking the most suitable representation of a population in a survey that could be daunting or impossible if the whole population had to be studied. In that respect, the concept is widely applied in market research where different sampling techniques are applied for different types of population. Thus, this analysis seeks to demonstrate the application of different sampling techniques using a case of Nevada National Bank that seeks to use its list of 400,000 credit card users who are spread all over the United states to test for the relationship between socio-economic characteristics ...

Introduction

Sampling refers to the statistical technique of selecting a population subset in order to make observations, as well as statistical inferences. Usually, social science research involves inferring behavioral patterns within particular populations (Frankfort-Nachmias & Nachmias, 2008). Consequently, cost constraints and feasibility necessitate the selection of a sample in order to analyze a particular population. Nevertheless, it is crucial to determine a sample that is adequately representative of the population. Such a sample increases the accuracy of results and inferences. Thus, sampling enhances the quality of observations by ensuring that the units under study are representative of the broader population. An overall sampling strategy is useful ...

Generalizability

Husserl distinguishes procedure of generalization and specialization of procedures of formalization and deformalization. Generalization is the transition from the spirit to higher on the tree of generic entities and formalization - a "meaningful generalization in a purely formal logic." For example, the transition from "red" to "sensory quality" is a generalization, and the transition from "red" to "adjective" or "chalk" to "beings" or "existing" is a formalization. Similarly, deformalization is filling the empty logical form something meaningful and specialization - descent of the tree of generic. Examples of both we find in mathematics. Example of formalization: the transition from an intuitive understanding ...

A research sample is considered not necessary when dealing with a population that is considered to be under the same authority. That is a population that follows a directive from the same chain of command. Such a population it is believed would follow the same route and give the same answers to an inquiry made as to their mode of conduct. This kind of assumption was made, for instance, when researching about the conduct of the so-called disciplined forces. Its results were practical, for example on Stanley Milgram's research on obedience to authority. To prove to the readers that the Germans were in ...

Introduction

Causal-comparative research is a technique that involves the determination of cause or consequences of the differences that exist between two or more groups. In this approach, two or more groups are examined and the possible cause, effects, or consequences of the differences between the groups are identified. This approach helps to identify associations that exist between variables.

Activity 16.1

In this activity, some questions would lend themselves well as causal-comparative research. One of them is “which subjects do high school students like least?” This question evaluates the effects of being a high school student. For example, girls would end up disliking a science subject ...

Participants

The population that was sampled in this study was all mothers that gave birth to infants with a birth weight of less than 2500g at Tuanku Jakaar Hospital over a five-month period. This population was highly relevant to the study. The study employed random sampling to choose the respondents1. The study of all births taking place on the same day, with no exceptions, gave a proper representativeness of the population. Random sampling ensured that the respondents were a representative of the population in Malaysia. Taking into account all the races in the diverse Malaysian population, the study avoided a recruitment bias that would have ...

A research proposal consists of many integral parts that work together to outline a viable project and produce a path to any answer (Babbie 2011). With each element of a proposal scrutinized, the sample design is a commonly discussed component. A sample is defined as a process that asserts that a portion of an appropriate size, in a relevant setting yields results that can be applied to a larger population as a whole (Lohr 2009). Sampling is needed in order to contain cost components of a project that may otherwise make it prohibitive. This definition defines the reach of the project and the scope of the evidence, making the ...

The main purpose of sampling is to provide qualitative or quantitative information of nature about a scenario by only examining few selected units from the whole. The sample represents the whole nature and the results from the sample give the results of the whole nature. Sampling allows the researcher to avoid wasting time in examining everything in the study area. The sampling method is a scientific procedure that selects units which provides the required estimates to determine the nature of the whole by examining part. The fundaments of sampling are: Population; Is the collection of all the things that are ...

- Convenience sampling: it’s a non-probability technique where the subjects are chosen because of their proximity or convenient accessibility to the researcher. A good example when the researcher is short for time or resources. He would conveniently choose subjects easily accessible to save on transport cost (Levy & Stanley 25). - Cluster sampling: it is a technique where the whole population is divided into clusters and a random sample from these clusters is selected. This technique would be appropriate when the random sample is scattered so widely that surveying the subjects would be very expensive (Levy & Stanley 21). - Systematic ...

Random Sampling

Simple random sampling is the most widely used statistical tool in large populations, where each unit or sample of a population is considered during analysis. Random sampling is considered to be ‘God standard’ of all the types of sampling techniques available. The major reason of random sampling being important is that it reduces any possible human bias. This includes bias created in selection of a sample or case to be included in the study sample. This technique represents the entire population, avoiding any possible missing data. The overall technique is simple, accurate and should be used for smaller population size. Generalizability ...

Multilevel study finds no link between minimum wage and crime rates. Article by Dawn Fuller

In general, there are two types of statistical procedures. These include inferential statistics and descriptive statistics. However, the above study is said to have utilized interferential statistics. Ideally, inferential statistics lays its focus on making inferences or predictions regarding a population using the analyses and observations of a sample. The rational for reaching on the conclusion that the above study employed inferential statistics is largely pegged on its mode of analysis: inferential statistical tests. The study employed an econometric time series analysis to analyze its datasets, which is referred to as the autoregressive integrated-moving average (ARIMA). There are three types ...
