Data analysis involves the examination, modelling, and alteration of data in order to extract meaningful information, make conclusions, and aid in decision-making. A lot of different techniques are used in this area, from math and statistics to machine learning and predictive modelling. Data analysis allows one to interpret complex data sets and turn them into information that can be used to improve business outcomes, eliminate inefficiencies, and identify market trends. It’s a critical component of any research or business strategy.
