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.
Lowestoft (/ˈloʊ(ɪ)stɒft, ˈloʊstəf/) is an English North Sea coast town and civil parish in the county of Suffolk. On the edge of The Broads, it is the most easterly UK settlement, 110 miles (177 km) north-east of London, 38 miles (61 km) north-east of Ipswich and 22 miles (35 km) south-east of Norwich. As the main town in the district of East Suffolk, it had an estimated 73,775 inhabitants in 2018. A port town, it developed out of the fishing industry and as a seaside resort with wide, sandy beaches. As its fisheries declined, oil and gas exploitation in the southern North Sea in the 1960s added to its development, alongside nearby Great Yarmouth. These roles have declined, but it is developing as a regional centre of the renewable energy industry.
