This guide goes into the fundamentals of data analytics, including its procedures, tools, and importance across sectors.
What is Data Analytics
Data analytics transforms raw data into actionable insights. It encompasses a variety of techniques, technologies, and methods used to identify trends and solve problems utilizing data. Data analytics can influence corporate processes, improve decision-making, and drive growth.
Types of Data Analytics
We have 4 main categories of data analytics which are Descriptive Analytics, Diagnostic Analytics, Predictive Analytics and Prescriptive Analytics.
1.Descriptive analytics: this is the process of parsing historical data to better understand the changes that occur in a business. Using a range of historic data and benchmarking, decision-makers obtain a holistic view of performance and trends on which to base business strategy.
Diagnostic analytics: this is a form of advanced analytics that examines data or content to answer the question, “Why did it happen?” It is characterized by techniques such as drill-down, data discovery, data mining and correlations.
Predictive analytics: is the process of using data to forecast future outcomes. The process uses data analysis, machine learning, artificial intelligence, and statistical models to find patterns that might predict future behavior.
Prescriptive analytics: is the use of advanced processes and tools to analyze data and recommend the optimal course of action or strategy moving forward.
The Data Analytics Process
Data Collection: this is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated research questions, test hypotheses, and evaluate outcome.
