Unordered data or replicates

Beach Pebble mass

Unordered or random data is defined as "unordered or randomly selected measurements from a subset of a statistical population or sample," e.g. height measurements of students in a classroom; density, porosity, permeability, or chemical composition measurements of rocks collected from a particular formation; temperature and salinity replicates at a specific ocean depth; etc. Frequency plots or histograms are often used to visualize results of such measurements.
