Data Analytics Applications: Types, Use Cases, and Top Tools

How much do you know about data analytics? Specifically, how aware are you of its many applications in day-to-day situations? This article explores a sample of today’s typical data analytics applications, defines the term, calls out some popular tools, and finishes with an immersive data analytics program you can take to gain the right skills.

So, before we show how pervasive data analytics is today, let’s define the term and break down the four types.

What is Data Analytics?

Data analytics involves collecting, organizing, and analyzing data to draw meaningful insights and trends. It allows organizations to discover valuable information to foster informed decision-making and improve business outcomes. Additionally, data analytics employs different techniques and tools to process unstructured and structured data, discover hidden patterns, and provide actionable recommendations.

The Four Types of Data Analytics

All forms of data analytics fall under one of the following four categories.

Descriptive Analytics

Descriptive analytics asks the question, “What has happened?” Descriptive analytics looks backward, not forward, providing a comprehensive picture of previous events unfolding. The chief benefit of descriptive data analysis is that it helps data analysts understand what happened and why. Typical examples include:

• Dashboard reporting
• Fraud detection
• Product demand forecasts
• Sales performance

Diagnostic Analytics

Diagnostic analytics asks the question, “Why did this happen?” It examines the factors leading to an event to explain why the issue occurred. This form of analysis helps organizations understand what happened, why, and how the incident can be prevented from happening again. Popular examples of diagnostic analytics include:

• Drill-down
• Regression analysis
• Retrospective analysis
• Root cause analysis

Predictive Analytics

Predictive analytics asks the question, “What is going to happen in the future?” Predictive analysis uses existing data to predict future outcomes and trends. Organizations commonly use predictive analytics when they develop new products or services because it gives them a reasonable estimate of their customer’s future needs and wants based on past behavior. Examples of these analytics include:

• Customer Pricing
• Direct Marketing
• Retail Sales Forecasting

Prescriptive Analytics

Prescriptive analysis asks the question, “What should we do?” This analysis type takes predictive analytics a step further by using past data and trends to suggest future actions. This type of data analysis is particularly helpful in optimizing resources and uncovering new business opportunities. Additionally, prescriptive analytics can be used to make decisions or offer recommendations that allow others to make better decisions and do it faster. For example, a prescriptive model can recommend whether an organization should:

• Bid on a new project, and the asking price
• Build a new manufacturing plant or close an existing one
• Hire extra staff for a particular department
• Initiate a new product line or discontinue a current one
• Send a targeted ad to a chosen group of customers

Now that we know all we need to know about data analytics, let’s look at some popular data analytics applications.
