Question

identify whether the variable in the information below is qualitative or quantitative. government agencies carefully monitor water quality and its effect on wetlands (reference: environment protection agency wetland report epa 832 - r - 93 - 005). of particular concern is the concentration of nitrogen in water draining from fertilized lands. too much nitrogen can kill fish and wildlife. twenty - eight samples of water were taken at random from a lake. the nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample.
o quantitative
o qualitative
o qualitative as well as quantitative
o neither qualitative nor quantitative
o information does not have any variable.

Explanation:

Quantitative variables are numerical. Here, the nitrogen concentration (in milligrams of nitrogen per liter of water) is a numerical measurement. So it is a quantitative variable.

Answer:

quantitative
