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]
Wiltshire (/ˈwɪlt.ʃər, -ʃɪər/;[2] abbreviated Wilts) is a historic and ceremonial county in South West England with an area of 3,485 km2 (1,346 square miles).[3] It is landlocked and borders the counties of Dorset, Somerset, Hampshire, Gloucestershire, Oxfordshire and Berkshire. The county town was originally Wilton, after which the county is named, but Wiltshire Council is now based in the county town of Trowbridge. Within the county's boundary are two unitary authority areas, Wiltshire and Swindon, governed respectively by Wiltshire Council and Swindon Borough Council.
Wiltshire is characterised by its high downland and wide valleys. Salisbury Plain is noted for being the location of the Stonehenge and Avebury stone circles (which together are a UNESCO Cultural and World Heritage site[4]) and other ancient landmarks, and as a training area for the British Army. The city of Salisbury is notable for its medieval cathedral. Important country houses open to the public include Longleat, near Warminster, and the National Trust's Stourhead, near Mere.
