A qualitative observation has to do with things you can't count, "The fish has black scales" is a qualitative observation.

You can combine these two, an example would be "The fish has 125 black scales."
qualitative observation and quantitative observation

qualitative observation and quantitative observation
The difference is that qualitative is wade with 1 of your 5 senses and the other one which is quantitative is an observation involving numbers.
quantitative observation is observing numbers such as "there are twenty potatoes". Qualitative observation is observing anything that is not countable such as "the potatoes are all brown"
A quantitative observation involves a numerical value e.g. The ball's mass is 10 g A qualitative observation does not e.g. The ball is red
Scientists often find that quantitative observation is more important than qualitative observation.
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.
