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]

​North Wales (Welsh: Gogledd Cymru), also known as the North of Wales (or simply the North, or in Welsh 'y Gogledd' in Wales), is a geographic region of Wales, encompassing its northernmost areas. It borders Mid Wales (or South Wales under some definitions) to the south, England to the east, and the Irish Sea to the north and west. The area is highly mountainous and rural, with Snowdonia National Park (Parc Cenedlaethol Eryri) and the Clwydian Range, known for its mountains, waterfalls and trails, located wholly within the region. Its population is more concentrated in the north-east, and northern coastal areas of the region, whilst significant Welsh-speaking populations are situated in its western and rural areas. North Wales is imprecisely defined, lacking any exact definition or administrative structure. For the public purposes of health, policing and emergency services, and for statistical,[1] economic[2][3] and cultural[note 2][4] purposes, North Wales is commonly defined administratively as its six most northern principal areas, but other definitions of the geographic region exist, with Montgomeryshire historically considered to be part of the region.

Those from North Wales are sometimes referred to as "Gogs" (from "Gogledd" – the Welsh word for "north");[5] in comparison, those from South Wales are sometimes called "Hwntws" by those from North Wales.

The region includes the localities of Wrexham, Deeside, Rhyl, Colwyn Bay, Flint, Bangor, Llandudno, and Holyhead. The largest localities in North Wales are the town of Wrexham and the conurbations of Deeside and Rhyl/Prestatyn, where the main retail, cultural, educational, tourism, and transport infrastructure and services of North Wales are located.
