Chapter Summary
Understand the fundamental need to classify raw data to bring order, make it comprehensible, and prepare it for further statistical analysis and inference.
Define raw data as unclassified, disorganised data collected from a source, and recognize its limitations for drawing meaningful conclusions without proper organisation.
Understand the method of classifying data based on time periods such as years, months, or weeks, often presented in ascending or descending order. This forms a time series.
Understand the method of classifying data based on geographical locations like countries, states, cities, or districts.
Understand the method of classifying data based on non-numerical attributes or characteristics, such as gender, nationality, or marital status.
Understand the method of classifying data based on measurable, numerical characteristics like height, income, or marks. The data collected on such characteristics are called variables.
Differentiate between classifying data based on non-measurable attributes (qualitative) and classifying data based on measurable numerical values (quantitative).
