tumblr_os9q20NQct1r2r773o8_1280.jpgdata analyst Analysis is the process of systematically applying statistical or logical techniques to describe and illustrate, condense and recap, and evaluate information. According to Shamoo and Resnik various analytic procedures"provide a method of drawing inductive inferences from data and identifying the signal (the phenomenon of interest) from the noise (statistical fluctuations) within the information".
Whilst data analysis in qualitative research may include statistical processes, many times analysis becomes an ongoing iterative process where data is continuously collected and analyzed almost concurrently. Indeed, researchers generally analyze for patterns in observations throughout the entire data collection phase. The form of the investigation is determined by the particular qualitative approach taken (field research, ethnography content analysis, oral history, biography, unobtrusive research) and the form of the data (field notes, documents, audiotape, videotape).
An important part of ensuring data integrity is the precise and appropriate evaluation of study findings. Improper statistical investigations distort scientific findings, mislead casual subscribers, and may negatively influence the public perception of study. Integrity issues are equally pertinent to analysis of non-statistical data as well.
Considerations/issues in data analysis
There are a number of issues that investigators should be cognizant of respect to data analyst analysis. These include:
Having the necessary abilities to analyze
Concurrently selecting data collection methods and Proper analysis
Drawing unbiased inference

Determining statistical significance
Lack of clearly defined and objective outcome dimensions
Providing accurate and honest analysis
Manner of presenting data
Environmental/contextual Troubles
Data recording System
Training of staff conducting analyses
Extent of investigation
A tacit premise of investigators is they have received training sufficient to demonstrate a high standard of research practice. Unintentional'scientific misconduct' is probably the result of poor follow-up and business intelligence instruction. A number of studies indicate this may be the case more frequently than believed. For example, Sica discovered that sufficient training of doctors in medical schools in the proper design, implementation and evaluation of clinical trials is"abysmally little". Indeed, business intelligence a single class in biostatistics is that is usually offered.
A standard practice of investigators would be to defer the selection of analytic procedure to a research team'statistician'. Ideally, researchers should have substantially more than a basic understanding of the rationale for choosing one method of investigation within another. This can allow researchers to better manage employees who run the data investigations process and make informed decisions.
While methods of investigation may differ by scientific discipline, the optimal stage for discovering appropriate analytical procedures happens early in the research process and shouldn't be an afterthought. Based on Smeeton and Goda,"Statistical advice ought to be obtained at the stage of initial preparation of an investigation in order, for instance, the method of sampling and design of questionnaire are suitable".
The main goal of analysis is to differentiate between an event happening as reflecting a legitimate effect versus a fictitious one. Any prejudice occurring in the group of this data, or selection of method of investigation, will increase the odds of drawing on a biased inference. Bias can happen when recruitment of study participants drops below minimum number required to demonstrate statistical power or failure to keep a sufficient follow-up period needed to demonstrate an effect.
