Particle size distribution

Some past research limitations include a small sample size, no control group, insignificant difference between dose levels and only comparing HAI to no HAI. Having a small sample size is a limitation because it is uncertain if the results of the study can be generalized. No control group can be a limitation because there is nothing to compare the results of the study…

each research sought to advance our current knowledge, results will vary and may even rebut previous researches. Results may vary due to assorted differences between studies. For example, the research design, quantitative or qualitative, the sample size and selection, even the researcher’s preconceived opinion can play a role in the outcome of the research. Some researchers may show preference over particular variables which may sway results while conducting the research. Often times the…

METHODOLOGY Lambert (2012) defines methodology as the rationale for the methods you use to investigate and answer your research questions. Therefore, there must be an explanation for your chosen methodology in order to meet your aims of the research. The aim of my research is to uncover the answers of these questions: RESEARCH QUESTIONS 1) What do students and teachers define success as 2) What do students feel contributes to their success 3) What do teachers feel contributes to their pupils…

were 32 university students (12 men, 20 women) in the present work. They were randomly assigned to red, blue, and white test papers. Results showed a higher group means from the red test paper condition. This discrepancy is likely due to small sample size and habituation to the color stimuli over time. Comparison to other modes of test administration (i.e., computers) and implications to applied research were discussed for future directions. The ubiquity of color affects…

legitimacy, dependability, and generalizability of the study. Consequently, in a quantitative examination, prescriptive tenets for selecting tests and models for ascertaining sufficient sample size have created. A little haphazardly chose test damages both the quantitative rule that requires a satisfactory example size. Furthermore, with a specific end goal to guarantee representativeness and the subjective guideline of fittingness that requires intentional inspecting and a "decent" witness…

Introduction: Coffee is a popular ubiquitous beverage in the daily life of an undergraduate student. For many it is a habit that gradually forms and stays. Its popularity lies in the key ingredient, caffeine, which decreases fatigue and instead increases alertness, features that aid an undergraduate student 's academic performance when studying on little sleep and going through the day (Giles et al., 2012). However, besides coffee 's use as a stimulant, can it be used to influence cognitive…

It was hypothesized that HAI would have a positive effect on mood, as HAI increased, mood would also to increase. There was no main effect between HAI and mood. This could be due to a small sample size. With a larger sample size, it is possible that the HAI would have a more significant effect on mood. According to a literature review completed in 2001 by Allen, Shykoff, and Izzo, previous research suggests that HAI has a positive correlation on an individual’s…

findings. Many of the test scores did not show which testing style was more appropriate to teach with. Limitations are constricting to studies and this one holds a large one. The data given could not significantly show a good outcome because the sample size was too small. By using multiple universities the data would possibly have shown a more significant outcome. The authors state that they will be observing the two separate groups longitudinally throughout their nursing school career to…

surveys have been in use for quite some time, while technology has created a newer data collection method. Depending on the sample size and research strategy, each method has advantages and disadvantages that researchers must consider when designing the data collection method. Paper. Efficient and effective, paper-based surveys can quickly achieve wide-distribution to gain a broader sample. Paper-based surveys involve using pen and paper to collect data and optical scanning to record results…

Describe the sampling strategy. How appropriate were the various sampling design decisions? The sampling strategy is the first most important part of conducting this kind of research. According to Cooper and Schindler (2014) the most important characteristic of a sampling is to determine whether it represent the population it is supposed to represent. According to the article, “McMahon Group distributed mail surveys to 1,650 members and their spouses in January 1999” (Cooper & Schindler, NCRCC:…
