Explanation:

To solve this, we recall:

• Qualitative data: Non - numerical, describes a quality/characteristic (e.g., color, ethnicity, name).
• Quantitative data: Numerical, represents a quantity (can be counted/measured, e.g., age, number of siblings, scores).

A. Mother’s Age at Birth of Child

Age is a numerical value (e.g., 25 years, 30 years). So, it is quantitative.

B. Your phone number

A phone number is a sequence of numbers used as an identifier (not a quantity to measure/count). So, it is qualitative.

C. Ethnicity

Ethnicity (e.g., Asian, African - American) is a non - numerical characteristic. So, it is qualitative.

D. How many siblings you have

The number of siblings (e.g., 1, 2) is a numerical quantity. So, it is quantitative.

E. Date of birth

A date of birth (e.g., 05/10/2000) is used as an identifier (not a quantity). So, it is qualitative.

F. State/country in which you were born

The state/country (e.g., California, USA) is a non - numerical category. So, it is qualitative.

G. Unit Assessment Score

A score (e.g., 85, 90) is a numerical value representing performance. So, it is quantitative.
