Data Analysis Methods

What are the methods for performing data analysis?

There are a number of techniques for conducting data analysis, and the methods you select depend on the nature and needs of your business. These methods run the gamut from the basic to the complex and include:

  • fundamental business intelligence (BI)
  • reporting
  • online analytical processing (OLAP)
  • data mining
  • predictive analytics
  • machine learning


BI is an organisation’s technologies and strategies for extracting and analysing news, data and business information. As a whole, BI uses software and other services to transform raw data into useful, actionable insights that companies can use to drive strategic decision-making. BI can provide:

  • reporting functionality
  • tools for identifying clusters
  • support for data mining techniques
  • business performance management
  • predictive analysis.


Reporting organises and summarises raw data into useful information so organisations can see how areas within the business are performing. It can alert a company to changes, highlight patterns and trends, and raise questions about the company’s direction. Robust reporting can strongly influence organisations, prompting them to take action with the goal of business gain.


With this powerful computing process, users can quickly and easily extract multidimensional data so they can analyse it from different perspectives. OLAP enables complex calculations, trend analysis and advanced data modelling. It’s useful for budgeting, financial reporting, analysing trends, sales forecasting and more. Again, it provides organisations with more of the knowledge and insight they need for smart decision-making.

Data mining

Data mining involves sorting through, examining and categorising vast amounts of data to identify anomalies, correlations and patterns. It extracts and structures information into an understandable and useful form, and calculates future trends and outcomes. Data mining should move beyond internal data and look at additional data sets, such as filtered news datasets and company, regulatory and legal datasets information. Such robust data mining helps organisations solve problems and further drives decision-making.

Predictive analytics

Predictive analytics is an advanced form of analytics that allows organisations to look at current and historical facts and figures to make predictions about unknown future events. It draws on many techniques from data mining, statistics, machine learning, predictive modelling and artificial intelligence to make these predictions, identify and assess risks, pinpoint opportunities and ultimately guide decision-making.

Machine learning

Machine learning studies the algorithms and mathematical models that computer systems use to progressively improve their performance of a specific task. It’s based on the idea that systems can learn from data and information, find patterns and autonomously make decisions with little human intervention.
