Sampling and Empirical Research Studies
Quantitative scientific studies typically require sample sizes that are sufficiently large enough to produce valid interpretable data, and using a questionnaire-based survey to poll a large group of respondents is a traditionally accepted methodology within the realm of scholarly research. The objective of any survey-based sampling experiment is to translate raw statistical data on a testable subject of interest, obtained from a sizable sample of relevant respondents, into a viable theory. The strength of this approach lies in the fact that social phenomena are most effectively studied through a systematic empirical investigation of statistical data. Because surveys are generally designed to include an array of multiple choice, yes-or-no, and essay questions, the varied level of detail provided in each recorded answer is expected to provide substantial data. Statistical sampling is used within the field of nursing to identify patient...
Indeed, it has been consistently observed that "as a cost-effective and useful methodology, work sampling warrants more in-depth exploration of the various techniques involved to ensure nurse managers, clinicians and researchers appreciate the complexities of the approach and its potential to contribute to an understanding of nursing work. (Pelletier & Duffield, 2003).
However, a potential weakness tied to the use of survey-based sampling lies in the fact that any sample size, no matter how significant in terms of quantity, is inherently limited by the respondents' tendency towards selection bias. Whenever a researcher administers a survey to a randomized sample of individuals or organizations, the segment…

Another instance in which random sampling is not important is when a researcher is conducting a qualitative study. In qualitative studies, depth of information from selected units of analysis is given more importance rather than the number and representativeness of the target group or population. Thus, for a researcher conducting in-depth interviews of household mothers (for example), the characteristics/selection criteria set in identifying the target group (household mothers) are more
scientific observation that distinguish it from our everyday observation are that scientific observation is conducted using precisely defined observational conditions; by performing the observations systematically and objectively; and through keeping careful and accurate records. Scientific observation, as opposed to everyday observations, must take place within certain well-defined parameters, whether in naturalistic or laboratory settings. Furthermore, the scientist does not choose the parameters arbitrarily but rather relies on such methods as
Sampling Plan Before discussing a sampling plan, there has to be clear and unambiguous definitions of what a sample and sampling are. Despite diversity in the definition of a sample, the best meaning is that a sample could be considered as a subset of a population, with which a researcher would like to use as participants in a given research study (Landreneau & Creek, 2012). According to Deming (1990), sapling is
Scientific Research Collect Methods Comment by Sabina: Scientific research is obtainable through several methodologies, of which qualitative and quantitative methods are highly utilized. These two research methodology are highly used in the field of social sciences and marketing. Social scientist utilizes these two data collection tools to collect data that would otherwise not be observable without these tools. Marketing researchers utilizes these tools to collect information about the market, gain information about

Scientific and empirical research take time, and therefore detracts from the timeliness of such research. However, the truth level in such research is higher than in research that takes less time and is therefore more timely. The author points out that these are not the only factors involved in the quality of a piece, and that the purpose of publication should also be kept in mind when assessing the
