What is a dataset?

Observations about the world around us can lead to inferences about differences and patterns.

Science requires careful record-keeping and precision, which can be achieved through constructing datasets.

datasets come in various forms, with the rectangular long-form dataset being a commonly used one.

"data" is the plural form of "datum," with a dataset being a structured arrangement of datums.

The unit of observation is the "something" that the bits of information in the dataset are about, represented by a row.

In survey research, the unit of observation is typically an individual person, with variables such as age, gender, race, and income.

variables are characteristics about the unit of observation that have the potential to show variation.

Understanding the basics of creating a dataset involves seeing data as bits of information, knowing that rows represent units of observation, and understanding that columns represent variables.
