Data Analysis
Data analysisis the systematic process of inspecting, cleansing, transforming, and modeling data to discover useful information, draw conclusions, and support decision-making1. It involves applying various techniques and tools to extract meaningful insights from raw data, helping in understanding patterns, trends, and relationships within a dataset2.
Key Principles of Data Analysis
Data Collection: Gathering relevant data from various sources. This can include internal sources like a company's CRM software or external sources like government records or social media APIs1.
Data Cleaning: Preparing the data for analysis by removing duplicates, reconciling inconsistencies, and standardizing data formats1.
Data Analysis: Manipulating the data using various techniques to find trends, correlations, outliers, and variations1.
Interpretation: Interpreting the results to see how well the data answers the original question and making recommendations based on the data1.
Types of Data Analysis
Descriptive Analysis: This type of analysis helps describe or summarize quantitative data by presenting statistics. It answers the question, “what happened?”1.
Diagnostic Analysis: This analysis determines the “why” behind the data. It answers the question, “why did it happen?”1.
Predictive Analysis: Uses data to form projections about the future. It answers the question, “what might happen in the future?”1.
Prescriptive Analysis: Uses insights from the first three types of analysis to form recommendations for future actions. It answers the question, “what should we do about it?”
Understanding Data Analysis
Kingston upon Hull, usually shortened to Hull, is a port city and unitary authority area in the East Riding of Yorkshire, England.[2] It lies upon the River Hull at its confluence with the Humber Estuary, 25 miles (40 km) inland from the North Sea and 37 miles (60 km) south-east of York, the historic county town.[2] With a population of 268,852 (2022), it is the fourth-largest city in the Yorkshire and the Humber region after Leeds, Sheffield and Bradford.
The town of Wyke on Hull was founded late in the 12th century by the monks of Meaux Abbey as a port from which to export their wool. Renamed Kings-town upon Hull in 1299, Hull had been a market town,[3] military supply port,[4] trading centre,[5] fishing and whaling centre and industrial metropolis.[4] Hull was an early theatre of battle in the English Civil Wars.[5] Its 18th-century Member of Parliament, William Wilberforce, took a prominent part in the abolition of the slave trade in Britain.[6]
More than 95% of the city was damaged or destroyed in the blitz and suffered a period of post-industrial decline (social deprivation, education and policing).[7] The destroyed areas of the city were rebuilt in the post–Second World War period.[8] In the early 21st century spending boom before the late 2000s recession the city saw large amounts of new retail, commercial, housing and public service construction spending.
In 2017, it was the UK City of Culture and hosted the Turner Prize at the city's Ferens Art Gallery.[9] Other notable landmarks in the city are the Minster, the tidal surge barrier, the Paragon Interchange and The Deep aquarium. Areas of the town centre include the old town (including its museum quarter) and the marina. Hull University was founded in 1927 and had over 16,000 students in 2022.[10] Rugby league football teams include clubs Hull F.C. and Hull Kingston Rovers. The city's association football club is Hull City (EFL Championship). Hull RUFC and Hull Ionians both play in the National League 2 North of rugby union.
