Data analysis is the process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. [ 1] Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science ...
e. In statistics, exploratory data analysis (EDA) is an approach of analyzing data sets to summarize their main characteristics, often using statistical graphics and other data visualization methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling and thereby contrasts ...
Data science is an interdisciplinary field [ 10] focused on extracting knowledge from typically large data sets and applying the knowledge and insights from that data to solve problems in a wide range of application domains. The field encompasses preparing data for analysis, formulating data science problems, analyzing data, developing data ...
Analytics. Analytics is the systematic computational analysis of data or statistics. [ 1] It is used for the discovery, interpretation, and communication of meaningful patterns in data, which also falls under and directly relates to the umbrella term, data science. [ 2] Analytics also entails applying data patterns toward effective decision-making.
Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. [ 1] Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population.
Topological data analysis. In applied mathematics, topological data analysis ( TDA) is an approach to the analysis of datasets using techniques from topology. Extraction of information from datasets that are high-dimensional, incomplete and noisy is generally challenging. TDA provides a general framework to analyze such data in a manner that is ...
Big data analysis is often shallow compared to analysis of smaller data sets. [229] In many big data projects, there is no large data analysis happening, but the challenge is the extract, transform, load part of data pre-processing.
The concept of data management arose in the 1980s as technology moved from sequential processing [ 2] (first punched cards, then magnetic tape) to random access storage . Since it was now possible to store a discrete fact and quickly access it using random access disk technology, those suggesting that data management was more important than ...
