Question

Satellite database. The Union for Concerned Scientists (UCS) maintains the Satellite Database-a listing of the more than 1000 operational satellites currently in orbit around Earth. Several of the many variables stored in the database include country of operator/owner, primary use (civil, commercial, government, or military), class of orbit (low Earth, medium Earth, or geosynchronous), longitudinal position (degrees), apogee (i.e., altitude farthest from Earth's center of mass, in kilometers), launch mass (kilograms), usable electric power (watts), and expected lifetime (years). Which of the variables measured are qualitative? Which are quantitative?

Explanation / Answer

Qualitative variables (Variables which can't be measured in numerical figures) = Country of operator/ owner, Primary use and Class of orbit.

Quantitative variables (Variables which can be measured in numerical figures) = Longitudinal position, Apogee, Launch Mass, Usable electric power and Expected lifetime.

(Ans).
