Which 3 of the following are major varieties of data formats?

The answer is well-chosen because discrete data, structured data, and unstructured data are indeed major varieties of data formats relevant in data analytics.

Discrete data refers to values that can take on specific, distinct values, often counted (like the number of users) and is critical for many types of analysis in fields like statistics and data mining.

Structured data is organized in a predictable manner, often stored in relational databases, and is easily searchable. Examples include spreadsheets or databases that consist of rows and columns. This format is essential for traditional data analysis techniques.

Unstructured data, on the other hand, does not conform to a predefined data model. It can include text, images, audio, and video formats, which are increasingly significant as organizations strive to leverage insights from diverse data sources.

These distinctions between the types of data formats are fundamental in the realm of data analytics, as they dictate how data can be processed, analyzed, and utilized for decision-making and insights.
