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]
Rhyl (/rɪl/; Welsh: Y Rhyl, pronounced [ə ˈr̥ɨl]) is a seaside resort and community in the Welsh county of Denbighshire. It lies within the historic boundaries of Flintshire, on the north-east coast of Wales at the mouth of the River Clwyd (Welsh: Afon Clwyd). To the west is the suburb of Kinmel Bay and the resort of Towyn beyond, to the east Prestatyn, and to the south Rhuddlan. At the 2011 Census, Rhyl had a population of 25,149, with Rhyl-Kinmel Bay having 31,229.[2] The Abergele–Rhyl–Prestatyn conurbation numbers over 60,000. Once an elegant Victorian resort, an influx from Liverpool and Manchester after the Second World War changed the town's face. It had declined sharply by 1990, but has since been improved by major regeneration investments. Several million pounds of European Union funding to the Welsh Government has gone on developing the seafront.
