In statistics, data is a value or set of values associated with an event or phenomenon. It can be said that data is the basis of statistics, since all calculations are made from them and conclusions are drawn.
Data can be classified in a variety of ways, but can generally be grouped into two broad categories: raw data and processed data.
Raw data is data that has not been subjected to any type of treatment or analysis. It is a set of values without any specific order or meaning.
Processed data, on the other hand, are those that have been subject to a certain type of analysis or treatment. Therefore, they are organized and have a specific meaning.
Data can be collected in a variety of ways, but can generally be grouped into two broad categories: quantitative data and qualitative data.
Quantitative data refers to quantities and is expressed in numbers. For example, the number of inhabitants in a city, the number of vehicles circulating on a street on a given day, etc.
Qualitative data, on the other hand, refers to characteristics and is not expressed in numbers. For example, the color of a person's eyes, gender, age, etc.
Once collected, the data must be processed in order to draw useful conclusions. Various statistical techniques are used for this purpose, such as the calculation of descriptive measures or correlation analysis.
