Understanding data analytics

Data analytics definition

Data analytics is the process of analysing, interpreting, and visualising large, complex datasets to derive meaningful insights and make informed decisions. It encompasses a variety of techniques from statistical analysis to machine learning, aimed at analysing past and current data to predict future trends.

Why is data analytics important?

In its raw form, data is little more than a list of facts and figures. This is why it is often compared to oil, a resource whose value is latent until it’s processed into something useful. Data analytics is important because it helps extract value from the raw material we call data.

Imagine running a global supply chain with no insight into your data—or building a budget for your next product release based on gut feelings and intuition. Without data analytics, the goal of becoming a data-driven enterprise—with optimised operations and continuously improving customer experiences—can hardly be achieved. For organisations seeking to establish and maintain competitive advantage, data analytics is key for ongoing success.

How does data analytics work?

Data analytics is a multifaceted process involving various stages to extract meaningful insights from raw data. Specialised data analytics tools and teams play an essential role in this sequence, meticulously gathering, processing, and analysing data to derive actionable intelligence.

The following five steps help to ensure that data is accurately analysed, leading to actionable insights that drive strategic decision-making:

Step 1: Data collection

This initial step involves gathering data from various sources, such as databases, sensors, and online transactions. Collecting diverse datasets is crucial to gaining comprehensive insights.

Step 2: Data cleansing

Once collected, the data often contains errors, duplicates, or missing values. Data cleansing involves identifying and correcting these issues to ensure accuracy and reliability in subsequent analyses.

Step 3: Data transformation

Transforming data includes normalising, aggregating, and formatting it into a consistent and usable structure. This step prepares the data for efficient analysis by converting it into suitable formats and structures.

Step 4: Data modelling

In this phase, statistical models and algorithms are applied to the data to identify patterns, correlations, and trends. Modelling helps predict future outcomes and provides a basis for making informed decisions.

Step 5: Data visualisation

Finally, the analysed data is presented through charts, graphs, and dashboards. Visualisation makes complex data understandable and highlights key insights, enabling stakeholders to make strategic decisions quickly.

Types and techniques of data analytics

Types of data analytics

As data volumes grow, successfully navigating vast oceans of information requires different navigational tools depending on your destination. Increasingly, organisations approach data analytics by tailoring their strategies to answer targeted questions and achieve specific goals. Whether deciphering what happened in the past, uncovering the reasons behind those events, forecasting future possibilities, or recommending the best course of action, each type of data analytics offers unique insights and solutions. Here's a closer look at the four main types of data analytics: descriptive, diagnostic, predictive, and prescriptive.

Descriptive analytics

Descriptive analytics interrogates historical data to identify trends and patterns. It answers the "What happened?" question using techniques like data aggregation and data mining for insights into past performance. Examples include monthly sales performance reports, results from customer satisfaction surveys, and web traffic analyses that measure engagement rates.

Diagnostic analytics

Diagnostic analytics delves deeper into data to understand the causes of past events. It addresses the "Why did it happen?" question using techniques such as drill-down, data discovery, data mining, and correlations. For example, a retailer might use diagnostic analytics to understand why sales fell in a particular month by examining influencing factors.

Predictive analytics

Predictive analytics uses statistical models and machine learning techniques to forecast future outcomes based on historical data. It answers the "What might happen?" question by identifying trends and predicting future occurrences. One example would be a bank using predictive analytics to forecast the likelihood of a customer defaulting on a loan.

Prescriptive analytics

Prescriptive analytics recommends actions based on data analyses. It addresses the "What should we do?" question using techniques such as optimisation and simulation algorithms. For instance, a logistics company might use prescriptive analytics to find the most efficient route for delivery lorries.

The four types of data analytics

Data analytics techniques

Data analytics is a continuously evolving business discipline. The techniques employed can be as diverse as the datasets being examined and the goals organisations aim to achieve. To succeed with data analytics, a familiarity with the full range of data analytics techniques is a must. These include:

Data mining

Data mining uses algorithms and statistical methods to extract patterns and knowledge from large data sets. This technique helps organisations discover hidden patterns and relationships in data for use with various predictive models.

Text analytics

Text analytics parses unstructured text data from emails, social media posts, customer reviews, and other types of content to derive meaning, context, and insights. It is particularly useful for sentiment analysis, entity recognition, topic modelling, and natural language processing.

Statistical analysis

Statistical analysis uses statistical tests and models to understand relationships and trends within data. This technique includes hypothesis testing, regression analysis, and variance analysis to make inferences about the data.

Machine learning

Machine learning uses algorithms that learn from and make predictions on data, improving performance over time with more data. Common methods include supervised learning, unsupervised learning, and reinforcement learning, applied in areas such as recommendation systems and image recognition.

Data visualisation

Data visualisation is the visual representations of data through charts, graphs, and dashboards to make complex data more understandable. Effective visualisation helps organisations identify trends, patterns, and outliers quickly, aiding better decision-making.

Big Data analytics

Big Data analytics focuses on large volumes of data that traditional methods cannot manage effectively. It often involves distributed computing and storage solutions to process vast amounts of information, enabling organisations to leverage Big Data for strategic insights.

Examples and applications for data analytics

Examples of data analytics

Organisations use data analytics for a range of purposes. Some use it to predict equipment failures before they occur or customise marketing strategies to individual preferences. Others use it to streamline delivery routes for maximum efficiency or tap into the collective mood of social media users. Here are some of the most common examples of how data analytics helps to make these possibilities a reality:

Predictive maintenance

Data analytics is regularly used for predictive maintenance, where equipment or vehicle performance data is analysed to predict component failures. This helps organisations schedule timely maintenance and reduce unexpected breakdowns.

Customer segmentation

E-commerce platforms use data analytics for customer segmentation, analysing browsing and purchasing behaviour to group customers based on their preferences. This enables targeted marketing campaigns.

Supply chain optimisation

Organisations running logistics operations analyse shipment data to optimise delivery routes, reduce transportation costs, and improve delivery times. This helps ensure efficient operations and enhance customer satisfaction.
