How it differs from conventional statistics is in its scale and in the type of data it can handle. Fundamentally it’s just examining data to see if there’s a correlation between two different variables. Hypotheses about why these associations exist can then be formed.ĭata mining initially appears to be quite similar to normal statistics. Instead of formulating a hypothesis from observations and then collecting data to see if the hypothesis is true or not, as in conventional research, data mining uses data that has already been collected and analyses it to see if links between different variables can be found. It has developed as a research tool in response to the increasing power and capabilities of computers and technology over the last few decades, which allow far larger amounts of data to be simultaneously handled than was previously possible. Data mining is the process by which large-scale data sets are examined in order to find previously unknown links between different variables.
