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.
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"
Qualitative refers to what a sample is, while quantitative refers to how much of that materal is present.
Qualitative and quantitative data are both 2 important types of data. Qualitative data is data based on observation and description. An easy way to remember this, Qualitative ---> QUALity. Examples of qualitative data are when you record colors, smells, textures, etc... Quantitative data is based on numerical values. An easy way to remember this, Quantitative ---> QUANTity. An example of quantitative data are any type of numerical values.

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 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."
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".
qualitative observation and quantitative observation
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."
Qualitative observation is subjective. Quantitative observation is the result of controlled testing procedures with prescribed procedures in place. Quantitative testing is sometimes called empirical testing.

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.
The two kinds of observation are qualitative and quantitative. Qualitative observation involves descriptions and characteristics, such as color or texture, while quantitative observation involves measurements and numerical data, such as length or weight.
