Proper statistical analysis and expert knowledge brings objectivity to data, rendering it suitable for making confident decisions.
The nature of the analysis is reflective of the experimental design and does not always have to be complicated. In most cases, intelligent decisions can be obtained from a simple data analysis using the KISS principle (Keep It Small and Simple).
The type of analysis ranges from simple hypothesis testing to more advanced learning techniques. Regardless of the selected analysis, the goal is to understand how the data might be used to predict future performance.
