Quantitative observations involve numbers. An example would be the volume of 0.1M HCl needed to neutralise 25 ml of sodium hydroxide solution.
Quantitative information is given in terms of numbers. You would usually count or measure something. If you were observing children, an example would be their heights in metres. For cars, you might measure their speeds, or lengths, or masses, but observing their colours would not be quantitative.

Counting the number of objects in a set
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."
Numerical measurement
Subjective quantitative is when you answer subjectively but through numbers. example... how do you feel about busy shops from a scale of 1-10?
the process of science
Observation is the act of watching something.
Quantitative observation means that your description of what you observedincludes a definite number that you measured.For example:"I saw a really big guy." is not a quantitative observation."I saw a guy who is 8 feet tall." is a quantitative observation.
The word "quantitative" is from the root word quantity. So, a quantitative observation is one that can be quantified or counted. Any time you count or physically measure something, it is a quantitative observation. Since it is your homework you should come up with your own examples :)
An example of a quantitative observation is measuring the temperature of a substance using a thermometer and finding it to be 25 degrees Celsius.
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".
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.
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."
give at least 5 examples of qualitative observation
The opposite is a quantitative observation, such as the weight or length of an object. Quantitative observations have numbers, such as 3 pounds or 5 meters. You would be quantifying or measuring a thing.

A quantitative observation is something that measures a quantity (number), such as the weight of length of an object. Quantitative observations have numbers, such as 3 pounds or 5 meters. The opposite is a qualitative observation, such as something is round or that it is blue. There are no numbers involved, the thing is either round or it's not.
