At MGRM we do Exploratory data analysis (EDA) to summarize data’s main characteristics, often with visual methods. We see what the data can tell us beyond the formal modeling or hypothesis testing task. We formulate hypotheses that could lead to new data collection and experiments, which focuses more narrowly on checking assumptions required for model fitting and hypothesis testing, and handling missing values and making transformations of variables as needed.

The objectives of EDA are to:

  • Suggest hypotheses about the causes of observed phenomena
  • Assess assumptions on which statistical inference will be based
  • Support the selection of appropriate statistical tools and techniques

Provide a basis for further data collection through surveys or experiments
