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
Shrewsbury (/ˈʃroʊzbəri/ ⓘ SHROHZ-bər-ee, also /ˈʃruːz-/ ⓘ SHROOZ-)[1][2] is a market town, civil parish and the county town of Shropshire, England, on the River Severn, 150 miles (240 km) north-west of London. At the 2021 census, the parish had a population of 76,782.[3]
The town has Saxon roots and surviving institutions whose foundations date from that time and represent a cultural continuity possibly going back as far as the 8th century.[4][5]
The centre has a largely undisturbed medieval street plan and over 660 listed buildings,[6] including several examples of timber framing from the 15th and 16th centuries. Shrewsbury Castle, a red sandstone fortification, and Shrewsbury Abbey, were founded in 1074 and 1083 respectively by the Norman Earl of Shrewsbury, Roger de Montgomery.[7]
The town is the birthplace of Charles Darwin.[8] It has had a role in nurturing aspects of English culture, including drama,[9] ballet, dance[10] and pantomime.[10]
Located 9 miles (14 km) east of the Welsh border, Shrewsbury serves as the commercial centre for Shropshire and mid-Wales, with a retail output of over £299 million per year and light industry and distribution centres, such as Battlefield Enterprise Park, on the outskirts. The A5 and A49 trunk roads come together as the town's by-pass and five railway lines meet at Shrewsbury railway station.
