What does an observation refer to in the context of a dataset?

An observation in the context of a dataset refers to the specific data point or record that is represented by a single row in a table. Each observation encompasses all the relevant attributes or features that describe the item or entity being measured or analyzed, effectively capturing the details about that particular instance. For example, in a dataset of customer information, each customer's data, including their name, age, and purchase history, constitutes an observation.

By focusing on the attributes that describe the data contained in a row, this definition highlights the essence of what an observation signifies in data analysis. Each observation provides insights that can be utilized for statistical analysis, modeling, or decision-making, making it a fundamental element in the structure of datasets.
