Study design; Data analysis; Interpretation. The latter two of these are less serious than the first since they are correctable. Flaws in the study design may make it impossible to salvage anything of use from the research undertaken. The aim of this section is to provide a framework for designing a research study.

Nurs Res. 2010 May-Jun;59 (3):224-31. • Graphs, tables and numerical summaries are all examples of descriptive statistics • Inferential – Making predictions based on the data. – Inferential Statistics uses methods for making predictions about a population (total set of subjects of interest), based on data from a sample (subset of the population on which study collects data). This course is designed to teach sometimes tricky statistical concepts in an easy-to-understand business and real-world context. It relies on the innovative text “Introductory Statistics and Analytics: A Resampling Perspective” and intentionally references the growing field of Data Science. The course is divided into two four-week sections, Part 1 – Probability and Study Design, and Part 2 – Inference and Association.

Next Month, will discuss how to choose a statistical analysis method for data obtained from each study design. An inferential statistic that indicates if the data from an experiment are statistically significant. In order for the results to be statistically significant, this must be at or lower than 5%.
