The first will have numerical values associated wit the observations the second will not.
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."
The main difference between qualitative and quantitative research/observations are the purposes of the observations. Qualitative research uses a small number of cases to determine the underlying reasons and motivations of an action. Quantitative research uses a large number of cases to create a generalized result.
There are two main methods of research. These are quantitative and qualitative methodologies. Quantitative methods are based on numbers. that is statistics, measurements, values and calculations. Qualitative observes behaviors, visual characteristics and behaviors of what is/are being investigated. For example the Doppler Shift has qualitative characteristics of color (blue versus red shift). Quantitative aspects of the Doppler Shift of space objects would be their velocity, age, and compositions by percent.
Quantitative and Qualitative
quantitative and qualitative
Quantitate is how things are measured: height, length, volume while qualitative is the amount of something in something else. How much iron is in steel? How much silver in sterling silver?
There are many types of observations that can be applied in different fields. The common types are natural observation, casual observation, scientific observation, direct observation, objective observation and much more.
A quantitative [think 'quantity'] observation is an observation that you can relate specific numbers to. For example, a quantitative observation might be "It rained 1.5 inches yesterday." A qualitative [think 'quality'] observation is an observation that does not include specific numbers, such as "It rained a lot yesterday" or "It rained more yesterday than today."
They are both very good forms of research the main difference is the method in which the research is carried. In quantitative research there are more statistics involved. Everything is more mathematical in a sense, you're focused on the quantity. In qualitative research there is a focused on the quality of the work the questioning as to why things happen.
Researching and searching!

Research can be divided into two main categories: qualitative research, which focuses on understanding the "why" and "how" behind phenomena through qualitative data analysis; and quantitative research, which focuses on collecting and analyzing numerical data to answer research questions through statistical methods.
