Research Methods eBook.. Simple Statistical Analysis See also: Designing Research. Once you have collected quantitative data, you will have a lot of numbers. It’s now time to carry out some statistical analysis to make sense of, and draw some inferences from, your data.

The results in the attached spread sheet from the case studies are reliable because due to the type of analysis performed. Supplying the correct data to the statistical tool and then choosing the appropriate analysis generates refined data from which business decisions can be made with confidence.

Descriptive Statistics are used to present quantitative descriptions in a manageable form. In a research study we may have lots of measures. Or we may measure a large number of people on any measure. Descriptive statistics help us to simplify large amounts of data in a sensible way. Each descriptive statistic reduces lots of data into a simpler.

Statistical Methods in Medical Research is a highly ranked, peer reviewed scholarly journal and is the leading vehicle for articles in all the main areas of medical statistics and therefore an essential reference for all medical statisticians. It is particularly useful for medical researchers dealing with data and provides a key resource for.

Correct statistical analysis of results is crucial to the reliability of the conclusions drawn from the research paper. Depending on the study design and sample selection method emp observational or inferential statistical analysis may be carried out on the results of the study. It is important to identify if this is appropriate for the study.
