Datananalytiikkaa, or data analytics, is the process of examining raw data to draw conclusions about that information. It involves collecting, cleaning, transforming, and modeling data to discover useful information, inform conclusions, and support decision-making. The goal is to extract meaningful insights from data that can be used for various purposes, including business strategy, scientific research, and public policy.

This process often utilizes a combination of computer science, statistics, and domain expertise. Data analytics can be broadly categorized into several types: descriptive analytics, which summarizes past data; diagnostic analytics, which seeks to understand why something happened; predictive analytics, which forecasts future events; and prescriptive analytics, which recommends actions to take.

Tools and techniques used in data analytics range from simple spreadsheet software to complex machine learning algorithms and big data platforms. The interpretation of the results is crucial, as raw data itself does not provide answers; it requires skilled analysis to reveal patterns, trends, and relationships. Businesses leverage data analytics to improve efficiency, understand customer behavior, identify market opportunities, and mitigate risks. In scientific fields, it aids in hypothesis testing and discovery. The increasing volume and complexity of data make data analytics a vital discipline in the modern world.
