qualitative observation is the method of identifing a compound such as salt analysis,etc,. and quantitative is the calculation of the amount of a particular compound in a given sample such as asseys..
Think of it this way...
Qualitative- Quality (root word)
Quantitative- Quantity (root word)
Thus, qualitative observation is different from a quantitative one. Here's an example:
Qualitative Observation- I observed a classroom of 30 children for a 3-month period (1 hour/day). I observed their speech pattern as they engaged in oral activities in groups.
(This is an ex. of an observation that is done specifically and for a good time period)
Quantitative Observation- I observed 5 classrooms (a total of 150) children for a period of 2 days (2 hours total). *This kind of observation is based on quantity over quality.
Basically, qualitative data is something that you can feel or observe. (Such as, this cloth is soft, or this thing is heavy.)
Quantitative data, on the other hand, is something that you can measure. (Such as, this cloth is 50 yards long, or this thing weighs 50 kg.)
Hope this helps!
Quantitative observations are observations where some kind of measurement or count is made, so you end up with a number eg weight, height, rate etc.
Qualitative observations are observations which are descriptions, not measurements or counts eg the colour or shape of something.
Generally, in science quantitative results are more useful than qualitative ones. For example it is better to know that a new drug is twice as good as an old one (cures twice as many people, or works twice as fast) , rather than that it is just better.
A quantitative observation is one that is measurable and gives you a numeric, well defined measurement, e.g. the water bath increases in temperature by 3K every second. A qualitative observation is one in which there is no numeric measurement, e.g. the water bath gets hotter with time.

Quantative usually refers to numerical data. Qualitative, on the other hand, generates information using subjective means such as observations and interviews.

The observation that a solid is dissolving in water is qualitative in nature. If you wanted to make this a quantitative observation you would have to measure the quantities involved. For example, I placed 5 grams of NaCl in a beaker of 100 ml of water at a temperature of 20o Celcius, and did not stir, and it dissolved in 30 seconds. You may or may not need that information. If all you want to know is whether salt is soluble in water, the qualitative observation may suit your purposes. But in general, quantitative observations are more informative and lead to greater scientific insights.
It is quantitative.
Qualitative analysis produces a measured result, a set of figures, a graph whereas quantitative analysis produces a description, an 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."
qualitative observation and quantitative observation
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.
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.
Qualitative and Quantitative.
Qualitative refers to what a sample is, while quantitative refers to how much of that materal is present.
Sure. Quantitative observations: Measuring the temperature of water, counting the number of leaves on a plant, recording the weight of an object, timing how long it takes for a pendulum to swing, measuring the length of a book. Qualitative observations: Describing the color of a flower, noting the smell of freshly baked bread, observing the texture of a rock, listening to the sound of chirping birds, feeling the softness of a cotton fabric.
