Data analysts take raw data and analyze it to extract valuable insights. These insights are then presented visually, through graphs, maps, and charts, so that stakeholders can easily comprehend and act upon them. The practice of data analytics allows organizations to analyze all types of data, including real-time,
historical, unstructured, structured, and qualitative data, in order to identify patterns and generate insights that can inform decision-making and, in certain cases, automate processes, bridging the gap between intelligence and action. The specific insights obtained from data analysis depend on the type of analysis that is performed.
Data experts use four main types of analysis:
● Descriptive analysis
● Diagnostic analysis
● Predictive analysis, and
● Prescriptive analysis.
Data analytics can be classified into several categories, each with a distinct purpose. Descriptive analytics focuses on analyzing past events to understand what happened, while diagnostic analytics aims to determine the cause or reason why something occurred. Predictive and prescriptive analytics, on the other hand, look toward the future, using data to predict likely outcomes and recommend the best course of action based on these predictions.
Data analytics provides us with insights into past events and enables us to predict future trends and behaviors. By leveraging data, businesses and organizations can make informed decisions instead of relying on guesswork. Adopting a data-driven approach allows for a deeper understanding of their audience, industry, and overall
company, ultimately leading to better decision-making, improved planning, and a competitive edge in their respective markets.
