Theses statistics should only be retrieved after calling the ProfileData function. These values are all column-specific. String statistics are computed for all column types, including non string-based ones (such as numerics, date/times, etc.)

Quartiles and Medians

A median value is the 'middle' value. That is, if one were to order a list of 100 values from lowest to highest (including duplicate values), the median value is the value of the 50th item. There are two quartile values: first and third. In the previous example, the first quartile would be the 25th value, and the third quartile would be the 75th value. In cases where the total number of records is not evenly divisible, the value closest to the quartile or median point is used.
