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.
Buxton is a spa town in Derbyshire, in the East Midlands region of England. It has the highest elevation – about 1,000 feet (300 m) above sea level – of any market town in England.[nb 1] Close to the county boundary with Cheshire to the west and Staffordshire to the south, Buxton is described as "the gateway to the Peak District National Park". A municipal borough until 1974, Buxton was then merged with other localities lying primarily to the north, including Glossop, to form the local government district and borough of High Peak within the county of Derbyshire. It is also near to Greater Manchester. The population of the town was 22,115 at the 2011 Census.
Buxton landmarks include Poole's Cavern, an extensive limestone cavern open to the public, and St Ann's Well, fed by the geothermal spring bottled and sold internationally by Buxton Mineral Water Company. Also in the town is the Buxton Opera House, which hosts several music and theatre festivals each year. The Devonshire Campus of the University of Derby is housed in one of the town's historic buildings.
Buxton is twinned with two towns: Oignies in France and Bad Nauheim in Germany.
