A qualitative observation is used in chemistry, and is simply observing physical changes.
Qualitative observations are those that cannot be measured mathematically or assigned a value. For example, "the sky is blue," is a qualitative observation, it has no mathematical value associated with it. Quantitative observations are those that have a mathematical value. For example, "this desk is 1 meter long" is a quantitative observation. Therefore, noting that something is bubbling is an example of a qualitative observation.
A qualitative observation merely indicates that the subject possesses a certain quality, for example "this water is salty". A quantitative observation takes a measurement of the quality, for example "this salty water has a concentration of 10% salt".
No, empirical evidence is based on observation and inference. Qualitative observation is an observation of the qualities of an object. Quantitative observation, on the other hand, is an observation based on some sort of numerical measurement of the object.

A qualitative observation. For example, your gender, or the colour of your eyes.
A quantitative observation involves looking at the numerical aspects and properties of a substance. For instance, there are are 3.0 grams of sodium chloride in this weighboat. A qualitative observation is any observation that involves the qualities outside of the numerical aspects. For example, the sodium chloride is white.
Beauty, honesty and literacy.
This is an example of a qualitative observation, which involves describing qualities or characteristics of a specimen without measuring or quantifying them. In this case, noting the presence of 2 antennae on an isopod is a qualitative observation because it describes a visual characteristic without assigning a numerical value.

A qualitative observation has to do with things you can't count, "The fish has black scales" is a qualitative observation. A quantitative observation has to do with things you can count, "The fish has 125 scales" is a quantitative observation. You can combine these two, an example would be "The fish has 125 black scales."
yes
There are two types of observation. There is what is referred to as the qualitative observation and what is referred to as quantitative observation. Qualitative observations do not deal with numbers, but rather details of an experiment per se. An example would be how a precipitate looks that was formed from a reaction. Quantitative observations deal with numbers; an example would be the amount of a substance (in grams) formed from a completed reaction.
