ABSTRACT
Building on the concepts of the scatterplot and the smoothed scatterplot as data mining methods presented in Chapter 2, I introduce a new data mining method: a smoother scatterplot based on CHAID (chi-squared automatic interaction detection). The new method has the potential of exposing a more reliable depiction of the unmasked relationship for paired-variable assessment than that of the scatterplot and the smoothed scatterplot. I use a new dataset to keep an edge on refocusing another illustration of the scatterplot and smoothed scatterplot. Then, I present a primer on CHAID, after which I bring the proposed subject to the attention of data miners, who are buried deep in data, to help exhume themselves along with the patterns and relationships within the data.
