Types of data analysis

Descriptive analysis


  • Tracking KPI dashboards
  • Conducting overviews of sales leads
  • Reporting on the business’ monthly revenue

This is the most common type of data analysis and also the simplest. It is used by many businesses as it answers the question, “what happened?”

This data analysis method does this by summarizing the data from the past in dashboard form.

This data analysis type is used to track Key Performance Indicators, mostly known as KPIs. These determine how well or how poorly a business is performing based on certain benchmarks.

Diagnostic analysis


  • Investigating cause of delays in a company’s production
  • Establishing which marketing activities worked for the company
  • Establishing why targets were not reached
  • Establishing why revenues went high or dropped

This type of data analysis is next once you have already established what exactly happened.  It asks the question, “why did it happen?”

The diagnostic type of data analysis makes use of all the insights you gathered from the descriptive data analysis type and finds the causes of those results.

You can use this type of data analysis to establish more connections between the data you have collected and to identify the behavior patterns

This data analysis type creates more detailed information that helps even when new problems come up because it means you already have some kind of data pertaining to that particular issue. That way, you will not have to repeat work as all the problems are somehow interconnected.

Predictive data analysis


  • Risk assessment
  • Forecasting sales
  • Analyzing customer success teams
  • Determining the leads that will most likely convert

This type of data analysis is all about answering the question, “what next?”or “what is likely to happen?”

It simply makes logical predictions for the future using data from the past.

Statistical modeling is the basis for this type of data analysis which requires manpower and added technology to forecast. This forecast is normally an estimate because the accuracy of any prediction is dependent on the quality and detailed data.

It’s with this data analysis type that some businesses find difficulty because they don’t have the manpower to implement this type of data analysis in all the areas that they desire.

They are sometimes unable to invest in predictive analysis teams in all the departments or are not ready to educate the current teams they have.

Prescriptive data analysis


  • Determining the best marketing method to use
  • Determining whether to expand or downsize
  • Allocation of funds

This data analysis type is the most sought after by businesses but very few of them are well equipped to carry it out.

Prescriptive data analysis combines insights from the other three and determines how best to move forward from an existing problem.
