5 (a) Qualitative and Quantitative Observation
Observations can be either quantitative or qualitative. Quantitative observations deal with a number, or amount. Seeing that you have eight new e-mails in your inbox is a quantitative observation. Qualitative observations, on the other hand, deal with descriptions that cannot be expressed in numbers. Noticing that a bike is blue or that a grape tastes sour are qualitative observations.
