This classification focuses on qualities or categories that describe the data, such as colors, brands, types, or preferences. Examples include classifying people by gender, occupation, or education level.
Explanation of each option:
· (a) Chronological classification: This classification organizes data based on time, such as by year, month, or day. It doesn't focus on descriptive characteristics but on time-based aspects.
· (b) Geographical classification: This method organizes data based on geographical regions, such as countries, states, or cities. Like chronological classification, it focuses on the location, not descriptive attributes.
· (c) Qualitative classification: Correct answer. This method organizes data into categories based on descriptive characteristics. It is non-numeric and looks at the qualities of data, like gender, color, type, etc.
· (d) Quantitative classification: This method organizes data based on numeric values or measurable quantities (e.g., income, age, weight). It contrasts with qualitative classification, which focuses on descriptions rather than measurements.
