Types of data analysis:
Four different types of data analysis are widely used across all industries. Even though there are separated into different categories, yet they are all linked together and are the building blocks of each other.
- Descriptive Analysis
- Diagnostic Analysis
- Predictive Analysis
- Prescriptive Analysis
Descriptive Analysis:
Descriptive analysis is the first type of data analysis and is at the foundation of all data insight. You can consider this data type to be the simplest and most commonly used in today’s business. Descriptive analysis answers the “what happened” by summarizing past data. It usually does it in the form of dashboards. The descriptive analysis comes with different uses but the biggest one is it being used in business to track Key Performance Indicators (KPIs). The KPIs describe the performance of any business based on some specified benchmarks. You can follow here to understand the difference between Data Analytics vs Business Intelligence.
The business applications of descriptive analysis include the following:
- KPS dashboards.
- Monthly revenue reports.
- Sales lead overview.
Diagnostic Analysis:
Now that you have asked the main question which is “what happened”, the next step is to be implemented where you need to dive deeper and ask why it happened. This is the part where diagnostic analysis comes into action. The diagnostic analysis takes all the insights found from descriptive analytics and then drills it down to find the actual causes of these outcomes. The organizations seem to use this type of analytics often as it helps you create more connections between data and lets you identify patterns of a particular behavior. Here are pros and cons of using tableau.
The business applications of diagnostic analysis may include:
- A freight company who has to investigate the cause of slow shipments in a certain area or region.
- A SaaS company has to drill down so as to determine which marketing activities increased trials.
Predictive Analysis:
In this type of data analysis, you are to find the answer to the question “what is likely to happen”. In predictive analysis, the business uses previous data to make different predictions about future outcomes. This type of data analysis is one step higher than the descriptive and diagnostic analysis. Predictive analysis uses data that we summarize and then make logical predictions of the outcomes of the event. The Data analysis made relies on statistical modeling and requires added technology and manpower to forecast. But keep that in mind the forecasting is only an estimate and that the accuracy of predictions relies only on quality and detailed data. Check out interview questions for Data Science career.
