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..
An observation that does not involve a measurement is considered to be qualitative. This type of observation typically involves descriptions, characteristics, or properties of objects or phenomena rather than numerical values.
A Qualitative Observation is an observation that uses the five senses. sight, smell, hearing, touch, and taste. An example of this would be: "This tree has bright green leaves that have soft bumps on them." The opposite is a quantitative observation, which is measured in numbers, such as the weight or length of an object. For example, 5 pounds or 100 inches. For instance "The stratosphere begins 40 kilometers above the surface of Earth."
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.
ha ha... it could be either. Qualitative would be if you did a taste test to see if the green liquid (hopefully kool-aid) tasted good to different people. Quantitative would be if you measured how much of the green liquid there was. It isn't inherently either one, as qualitative and quantitative describe types of data, rather than things such as colored liquids of unidentified origin.
Toxicity can be both qualitative and quantitative. Qualitative toxicity refers to the presence or absence of harmful effects, while quantitative toxicity involves measuring the degree or severity of the toxic effects. Factors such as dose, exposure duration, and individual susceptibility can influence the quantitative assessment of toxicity.
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.
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.
Qualitative refers to what a sample is, while quantitative refers to how much of that materal is present.
Qualitative and Quantitative.
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.
