Data Analytics Types
There are four kinds of data analytics, and they all supplement each other, bringing value to any organization through their synergy.
Descriptive analytics evaluate events that occurred previously. Annual web traffic, quarterly sales, and monthly revenue are examples of such data.
These kinds of findings assist organizations in detecting generalizable trends.
Diagnostic analytics examine the reasons behind a data change by assessing and merging with descriptive data.
This helps determine patterns and dependencies. Moreover, it assists organizations in identifying reasons for a negative or positive outcome.
Predictive analytics look for ways to identify possible outcomes by observing common trends in diagnostic and descriptive analyses.
It allows organizations to take pre-emptive measures, such as reaching customers who aren't likely to renew contracts.
Prescriptive analytics aims to determine what actions ought to be taken. These sorts of analytics generate substantial value, addressing all potential issues before they take root.
They rely upon compound algorithms and cutting-edge technologies to stay up-to-date with industry trends—this includes machine learning.
A 2016 survey of more than 1900 business executives concluded that firms find descriptive data analytics inadequate for data-driven, informed decision-making.
On the contrary, predictive and diagnostic analytics are vital for organizations.
