Classification of data analytics
Data analytics methodologies consist of exploratory data analysis (EDA), whose aims is to find notions and relationships in information, and confirmatory data analysis (CDA), which can be infered to apply statistical techniques which can be used to determine whether hypotheses for a data set is either true or false. EDA is generally compared to detective work, while CDA is akin to the work of a judge or jury during a court trial — a distinction first drawn by statistician John W. Tukey in his 1977 book Exploratory Data Analysis.
