Question

Identify whether each of the datasets is quantitative or qualitative

a.  Types of computer software used in a database management system.

b. Life-lengths of laser printers

c.  Brands of calculators used by 100 engineering students on campus

d. Mileage attained by 12 automobiles powered by alcohol

Answer 1

a.  Types of computer software used in a database management system.

The types of computer software(viz. system software, application software etc.) cannot be quantified. Clearly, it's a qualitative dataset.

b. Life-lengths of laser printers

The life lengths of laser printers is a quantitative dataset as it will be expressed in terms of number of years or months.

c.  Brands of calculators used by 100 engineering students on campus

This type of data will be qualitative in nature. Because, the dataset will be represented in a sequence of various calculator brands viz. TI, Casio, Texas, HP etc.

d. Mileage attained by 12 automobiles powered by alcohol

Again, this will be a quantitative  type of dataset. The data will be a distribution of numbers expressed in miles per gallon or liters per 100 km unit.
