5. Income of a family is an example of

Correct Answer: Correct answer is: (A) Quantitative data.

Exam Relevance: AP Statistics, GRE, GMAT, SAT

Difficulty: Easy

Concept notes: Quantitative data refers to numerical information that can be measured and analyzed statistically. Income, being a monetary value, is a numerical measurement and thus falls under quantitative data.

Common Mistakes: A common misunderstanding is that income could be considered qualitative data because it might be categorized into different income brackets. However, the actual income value itself is numerical and therefore quantitative.

Explanations: Income is a numerical value that can be measured and analyzed statistically. It represents a specific amount of money earned, which is a quantitative characteristic. Qualitative data, on the other hand, describes qualities or characteristics that cannot be measured numerically.

Option Analysis:

Option A: Correct. Income is a numerical value and can be measured and analyzed statistically, making it quantitative data.
Option B: Incorrect. Qualitative data describes qualities or characteristics that cannot be measured numerically, such as opinions or feelings.
Option C: Incorrect. Saving is a concept related to financial management, not a type of data.
Option D: Incorrect. The correct answer is provided in the options.

10. What category would the following statement fall under? The mass of the chocolate cake is 250 g.

Correct Answer: Correct answer is: (B) Quantitative.

Exam Relevance: AP Statistics, GRE, GMAT, SAT

Difficulty: Easy

Concept notes: In quantitative research, data is expressed in numerical form, allowing for statistical analysis and measurement. The statement "The mass of the chocolate cake is 250 g" provides a specific numerical value, which is characteristic of quantitative data.

Explanations: The statement "The mass of the chocolate cake is 250 g" is quantitative because it provides a specific numerical measurement of mass. Quantitative data is characterized by its numerical nature, which allows for statistical analysis and comparison. The use of grams (g) as a unit of measurement further confirms the quantitative nature of the data.

Option Analysis:

Option A: Qualitative data describes qualities or characteristics and is often non-numeric. This option is incorrect because the statement provides a numerical measurement.
Option B: Quantitative data involves numerical measurements and is used for statistical analysis. This option is correct because the statement provides a specific numerical value for the mass of the chocolate cake.
Option C: The statement is not both qualitative and quantitative. It is purely quantitative as it provides a numerical measurement.
