VIA: NIST/engineering statistics handbook: Interpretation of Scatter Plots Conclusions from the scatter plots are: data set 1 is clearly linear with some scatter. data set 2 is clearly quadratic. data set 3 clearly has an outlier. data set 4 is obviously the victim of a poor experimental design with a single point far removed from the bulk of the data “wagging the dog”‘ (the NIST / Engineering Statistics Handbook (online)] is a pleasure to read. I like their style.)

“suggestive, indicative, and insightful” “subjective and depend on interpretation” Oh I’m liking EDA’s style. ” Classical Classical techniques serve as the probabilistic foundation of science and engineering; the most important characteristic of classical techniques is that they are rigorous, formal, and “objective”. Exploratory EDA techniques do not share in that rigor or formality. EDA techniques make up for that lack of rigor by being very suggestive, indicative, and insightful about what the appropriate model should be. EDA techniques are subjective and depend on interpretation which may differ from analyst to analyst, although experienced analysts commonly arrive at identical conclusions. “
