Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science, and social science domains. In today's business world, data analysis plays a role in making decisions more scientific and helping businesses operate more effectively.
Data mining is a particular data analysis technique that focuses on statistical modeling and knowledge discovery for predictive rather than purely descriptive purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing mainly on business information. In statistical applications, data analysis can be divided into descriptive statistics, exploratory data analysis (EDA), and confirmatory data analysis (CDA). EDA focuses on discovering new features in the data while CDA focuses on confirming or falsifying existing hypotheses. Predictive analytics focuses on the application of statistical models for predictive forecasting or classification, while text analytics applies statistical, linguistic, and structural techniques to extract and classify information from textual sources, a species of unstructured data. All of the above are varieties of data analysis.
Data integration is a precursor to data analysis, and data analysis is closely linked to data visualization and data dissemination.
Bournemouth (/ˈbɔːrnməθ/ (audio speaker iconlisten)) is a coastal resort town on the south coast of England. At the 2011 census, the town had a population of 183,491. With Poole to the west and Christchurch in the east, Bournemouth is part of the South East Dorset conurbation, which has a population of 465,000.
Before it was founded in 1810 by Lewis Tregonwell, the area was a deserted heathland occasionally visited by fishermen and smugglers. Initially marketed as a health resort, the town received a boost when it appeared in Augustus Granville's 1841 book, The Spas of England. Bournemouth's growth accelerated with the arrival of the railway, and it became a town in 1870. Part of the historic county of Hampshire, Bournemouth joined Dorset for administrative purposes following the reorganisation of local government in 1974. Through local government changes in 1997, the town began to be administered by a unitary authority independent of Dorset County Council, although it remains part of that ceremonial county. Since April 2019 the unitary authority has been merged with that of Poole, as well as the non-metropolitan district of Christchurch to create the Bournemouth, Christchurch and Poole unitary authority.
The town centre has notable Victorian architecture and the 202-foot (62 m) spire of St Peter's Church, one of three Grade I listed churches in the borough, is a local landmark. Bournemouth's location has made it a popular destination for tourists, attracting over five million visitors annually with its beaches and popular nightlife. The town is also a regional centre of business, home of the Bournemouth International Centre or BIC, and a financial sector that is worth more than £1 billion in gross value added.
