Types of Data Analytics
There Are Four Types of Data Analytics:
Predictive analytics are used to convert the data into useful knowledge. Predictive analytics uses data to estimate the chance of a condition arising or the likely course of an occurrence. To predict future events, predictive analytics uses a variety of statistical techniques from modeling, machine learning, data mining, and game theory. These methods examine both historical and present-day data.
Descriptive analytics looks at the data and analyses past events to discover how to approach future events. It studies past performance and analyses performance by analyzing historical data to ascertain what led to past success or failure. Almost all management reporting, including that for sales, marketing, operations, and finance, uses this type of analysis.
The descriptive model quantifies links in data to group consumers or prospects into categories. Unlike predictive models, which focus on predicting a specific customer’s behavior, descriptive analytics reveals a variety of interactions between the customer and the product.
To make a prediction, prescriptive analytics automatically combine big data, mathematical science, business rules, and machine learning. They then propose a decision option to capitalize on the prediction. In addition to advising activities that will profit from the projections, prescriptive analytics also outlines the ramifications of each decision alternative for the decision maker.
Prescriptive analytics not only anticipates what will occur when and how, but also takes into account why it will occur. Prescriptive analytics can also suggest choices for how to take advantage of a future opportunity or reduce future risk, as well as explain the ramifications of each recommendation.
In this study, while seeking to answer a question or solve a puzzle, historical data is often favored over other data. We search the historical data for any dependencies and patterns relevant to the specific problem. For instance, businesses use this analysis because it provides excellent insight into a problem. They also maintain detailed information about their disposal because otherwise, data collection might be time-consuming and individual for each issue. Data analyst course books will surely help to get mastery of it.
