Data Analyst
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.[1] 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.[2] In today's business world, data analysis plays a role in making decisions more scientific and helping businesses operate more effectively.[3]
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.[4] In statistical applications, data analysis can be divided into descriptive statistics, exploratory data analysis (EDA), and confirmatory data analysis (CDA).[5] EDA focuses on discovering new features in the data while CDA focuses on confirming or falsifying existing hypotheses.[6][7] 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.[8]
Data integration is a precursor to data analysis, and data analysis is closely linked to data visualization and data dissemination.[9]
Great Yarmouth, often called Yarmouth, is a seaside resort and minster town in Norfolk, England, straddling the River Yare, some 20 miles (30 km) east of Norwich.[2] A population of 38,693 in the 2011 Census made it Norfolk's third most populous place. Its fishing industry, mainly for herring, fell steeply after the mid-20th century and has all but vanished.[3] North Sea oil from the 1960s brought an oil-rig supply industry that now services offshore natural gas rigs. More recent offshore wind power and other renewable energy have created further support services. Yarmouth has been a seaside resort since 1760 and a gateway from the Norfolk Broads to the North Sea. Tourism was boosted when a railway opened in 1844, which gave visitors easier, cheaper access and triggered some settlement. Wellington Pier opened in 1854 and Britannia Pier in 1858. Through the 20th century, Yarmouth was a booming resort, with a promenade, pubs, trams, fish-and-chip shops and theatres, and the Pleasure Beach, the Sea Life Centre, the Hippodrome Circus and the Time and Tide Museum, and a surviving Victorian seaside Winter Garden in cast iron and glass.
