Qualitative observation deals with information that can be observed with our senses: sight, smell, touch, taste, and hearing.
This depends on what you are observing, but since number and amount are both measurements of quantity, they are somewhat interchangeable. Observations usually deal with both, because an observation is the action of observing something to collect information, and most information has to be quantified in order to be useful. And when quantifying something, a number or an amount has to be used.
=Science is a systematized body of knowledge which deals on the observation and classification of facts from which conclusions are derived. =
A hypothesis is based on you observation, and experiments on what you are going to do. If your hypothesis is wrong or doesn't match the results you had, you would need to modify it, so basically a hypothesis deals with prior knowledge.
