What is Data Analytics?
Data analytics is the process of collecting, cleaning, analyzing, and interpreting data to gain insights that can be used to make better decisions. It is a broad field that encompasses a variety of techniques and methods, such as statistics, machine learning, and artificial intelligence.
Data analytics can be used in a wide variety of industries, including healthcare, finance, retail, and manufacturing. It can help businesses to improve their operations, make better marketing decisions, and develop new products and services.
What are the different types of data analytics?
There are three main types of data analytics: descriptive, predictive, and prescriptive.
Descriptive analytics: This is used to summarize and describe data. It can be used to answer questions like “What happened?” and “What is happening?” Descriptive analytics is the foundation of data analytics and is used to understand the past. It can be used to create reports, dashboards, and visualizations to help businesses understand their data.
Predictive analytics: This is used to make predictions about the future. It can be used to answer questions like “What is likely to happen?” and “What will happen if I do this?” Predictive analytics uses statistical models to identify patterns in data and make predictions about future events. It can be used to forecast demand, identify fraud, and target marketing campaigns.
Prescriptive analytics: This is used to recommend actions. It can be used to answer questions like “What should I do?” and “How can I improve this?” Prescriptive analytics uses optimization models to find the best course of action based on a set of criteria. It can be used to optimize supply chains, allocate resources, and make pricing decisions.
These are just the three main types of data analytics. There are many other types of data analytics, such as text analytics, image analytics, and social media analytics. The type of data analytics that is used depends on the specific needs of the business or organization.
