Exploratory Data Analysis
Mathematica efficiently implements state-of-the-art data classification algorithms, allowing you to search for nearest neighbors and do cluster analysis on large datasets.
BinCounts count the number of elements that lie in bins
BinLists  ▪ Tally  ▪ Union  ▪ Commonest  ▪ Quantile
FindClusters find clusters in numerical, discrete and string data
Nearest find nearest neighbors in any space of data
Cases, Count list, count elements matching a pattern
Split split data into runs
