Description of the Types of Analytics and Examples

Analytics is the science of analyzing raw data in order to achieve a better understanding of the raw data and/or system and to make conclusions about that information. The aim of analytics has been said to provide better support to the decision-making process.

There are four types of analytics – descriptive, diagnostic, predicative and prescriptive.

Descriptive analytics consider the historical aspect of the data. It can organize the data into a convenient form including, but not limited to graphs, tables and control charts to further understanding for non-analysts. It is said to answer the question of what happened. Examples of descriptive analytics include: Summarization of a particular business result after a change is made to a process Determination of whether a quality problem exists in the manufacture of a product

Diagnostic analytics consider identification of positive and negative anomalies that are uncovered after looking at the output of the descriptive analytics and trying to determine why that (those) anomalies occurred. Diagnostic analytics is synonymous with root cause analysis. Examples of diagnostic analytics include: Determination of the cause of a spike in sales of a product, or better yet, sustained increase in sales Determination of why a product unexpectedly deviates out of its control parameters and worse yet, its specification parameters.

Predictive analytics utilize data and statistical models to determine what might happen with various data scientist given scenarios. It is complex and uses sophisticated tools. Wikipedia writes that the following scientific disciplines comprise predictive analytics Machine Learning Operations Research Computer Vision Natural Language Processing Applied Statistics Signal Processing Image Processing Metaheuristics Date Mining Examples of predictive analytics include: Using spending patterns, outstanding credit balances, income sources and other financial measures to calculate credit scores which will predict a person’s ability to afford a mortgage, a new credit card or an auto loan. Using spending patterns to identify excess spending such as might occur when one’s credit cards are stolen.

Prescriptive analytics suggests a range of prescribed actions and the potential outcomes of each of the actions. It may even go so far as recommending one of the prescribed action / potential outcomes as being superior. Examples of prescriptive analytics include:

Self-driving cars. Given a location and destination, prescriptive analytics will consider a range of driving paths, speeds and traffic to safely travel from start to finish in the shortest amount of time. It also updates the prescription as time goes on. Air travel. If bad weather suddenly appears at an airport, prescriptive analytics will consider how to safely hold and/or re-route incoming traffic until conditions improve and route these to the air traffic controller.
