Exploratory Data Analysis
Mathematica efficiently implements state-of-the-art data classification algorithms, allowing you to visualize distributions, search for nearest neighbors and do cluster analysis on large datasets.
Histogram, Histogram3D create histograms from data
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
