A sample of population is a small group of individuals that is selected from a larger population for the purpose of studying and collecting data. Sampling is the process of selecting this sample of population in a systematic and representative manner.

In a thesis, sampling is an important aspect of the research process as it helps to ensure that the findings of the study are accurate and reliable. By selecting a representative sample of the population, researchers can make generalizations about the larger population based on the characteristics of the sample.

There are several types of sampling techniques that can be used in a thesis. One common technique is random sampling, in which individuals are selected from the population at random. This type of sampling is useful because it allows for a high degree of accuracy, as all individuals in the population have an equal chance of being selected.

Another technique is stratified sampling, in which the population is divided into subgroups or strata, and a random sample is selected from each stratum. This technique is useful when the population is heterogeneous and the researcher wants to ensure that the sample is representative of the various subgroups within the population.

A third technique is convenience sampling, in which the sample is selected based on the convenience of the researcher. This technique is often used when time or resources are limited, but it may not provide a representative sample of the population.

There are several factors to consider when selecting a sample for a thesis. The size of the sample is important, as a larger sample is generally more representative of the population than a smaller sample. The sampling method should also be appropriate for the research question being asked, and the sample should be chosen in a way that is ethical and respectful of the individuals being studied.

In conclusion, sampling is an important aspect of a thesis as it allows for the collection of accurate and reliable data from a representative sample of the population. By selecting an appropriate sample and sampling method, researchers can make generalizations about the larger population and draw meaningful conclusions from their findings.

(DOC) CHAPTER 3 RESEARCH DESIGN AND METHODOLOGY Population Sampling

It is exploratory because the data has been collected through unstructured interviews and questionnaires to explore the issues that influence Pakistani community intentions to adopt Internet banking services. Under mild conditions on the population size, observation times, regularity of the trajectories, sampling scheme, and smoothing bandwidth, we prove a Central Limit Theorem in the space of continuous functions. It will have clear objectives, derived from research question that specify the source from which research person be going to to collect data and consider the limitations that research people will inevitably have such as access to data like time, location and money, ethical issues saunders, 2000. The last technique is to use program logic models, which is a combination of pattern-matching and time-series analysis where the analysis specifies a complex chain of patterns over time. Data reduction stage of the analysis helps the researcher to make the data sorted, sharpen, focused, organized and discarded in order to be able to draw and verify conclusion ibid.

To accomplish this, the population is split up into various parts known as sampling units. The use of the archival information is difficult when this topic is coming research area. Following are the short explanation of above five research strategies: 3. We also establish the uniform consistency of a covariance function estimator and apply the former results to build global confidence bands for the mean function. This strategy is used when the research person need to contrast two variables and examine their cause and effect relationships Malhorta, 1996. Furthermore, I conducted a cross-case analysis to compare the different case study in order to find the resemblance and variation between the cases.

It ensures that each unit in your population has an equal chance of being chosen to achieve a random selection mechanism. The overall study design is developed for maximum exploitation of the study question. We can say that, it cannot create a causal research relationship among variables. After refining some questions and items within the questions, the second pilot study was run and asked respondents to check for the wording, coverage, relevancy of the items listed within the questions. The order of the questions was also subject to analysis and it was found to be suitable to have a disposition where the initial questioning concerned facts that the respondents easily could give an answer to.

Assuming functional data are collected from a finite population according to a probabilistic sampling scheme, with the measurements being discrete in time and noisy, we propose to first smooth the sampled trajectories with local polynomials and then estimate the mean function with a Horvitz-Thompson estimator. Reliability can be assed by the following three questions: Will the measure yield the same results on other occasions? It is just the opposite of the existing population. Power and effect size measurements will also be vital that you lending credibility for your study and therefore are easily calculated through the experts at Statistics Solutions. When we convey more data, then our decision could be more accurate and you will see less error from the parameter estimate. The final sample also needs to fully reflect the overall characteristics as much as possible.

Afterward, we can either use systematic or simple random sampling to select units from each sample. As such, they are the well-placed population to answer the questions regarding challenges and barriers that women of color face in their quest to attain management and leadership positions in corporate organizations. The sample size is appropriate because Lofland, Snow, Anderson, and Lofland 2006 then Rubin and Rubin 2011 conducted similar studies where a sample size of 10 and 20 was used. It is a process that helps a candidate proffer their research knowledge to an audience of accomplished academics. Then the relationship between sample and sampling can be understood as sampling is a process, and the sample obtained is the result. There are different types of population.

In this Population and sampling Population: Population in the context of statistics has a slightly different meaning than in everyday discourse. The usage of various sources of evidence can increases the validity of scientific study Yin, 1994. By using stratified sampling technique for the selection of representatives. Keeping the research in view we will draw the sampling frame as under. It may be extremely difficult or unaffordable to find respondents in these situations. The purposive sampling procedure is appropriate for the proposed study because participants are chosen randomly based on deliberate criteria such as their knowledge, understanding, and experience on the Big Data topic in a non-probability sampling strategy Babbie, 2007. It can include anything you wish to study, such as objects, events, companies, states, or microorganisms.

There are two different types of data sets namely, population and sample. Numbers of different steps were taken to ensure the reliability of the study: Case studies were used during the data collection. The role of reliability is to minimize the errors and biases in a study Yin 1994. According to Young 2021 , representative sampling is a sampling technique that allows a researcher to make conclusive remarks representing an entire population. The researchers created a total sample by selecting the appropriate proportion of the participants from each year level. This technique is easy to implement and has a better accurate result. Third, there may have been observer error that different interviewer may approach the questions in different ways.

This chapter presents the methods used in this research. It is estimated that each of these 10 companies has approximately 10 people each that have successfully performed Big Data Analytics. That group can comprise a nation or people sharing common characteristics. Practicality is another reason because gathering data from a sample is easier and more effective. The sample represents all of the characteristics of the population from which it is taken out. Then these 10,000 salary records constitute a sample for our research, and 10,000 is the sample.
