If you ran a chemical reaction in, for example a constant flux reaction calorimeter (CFRC) in which was fitted a near infrared (NIR) probe. And the reaction you wished to achieve was A+B=C. There may also be side reactions taking place eg A+B=D. The NIR probe would tell you the amount of C produced and is therefore a quantitative measurement. On the other hand, the enthalpy measurement from the calorimeter would give the total heat of both reactions and is therefore a qualitative measurement of C. Too much or too little heat will indicate that impurities are present, or that conversion is low. Interestingly enough; the optimum yield will be when the difference between the two measurements is a minimum. Thus using a combination of both the quantitative and qualitative data is the best way to achieve optimum yield.

A qualitative question is one that inquires something about its qualities like, characteristics. For ex, If the subject of the question is a spider, some qualitative questions would be, "What color is it, How does the exoskeleton feel? A quantitative question is one that involves quantities, numbers, calculations. For ex, in the same subject, "How many legs does it have, How long is its body, How long do they live?

In Chemistry, quantitative observation would say 13 grams of chemical A were produced in the reaction. Qualitative observation would say the reaction produced a flash of light and a green gooey substance.

Qualitative observation is your teacher observations and insights get from the interviews, talks with your respondents etc..
Quantitative observation is data gathered by means of tests, surveys, questionnaires. In other words you can count the results and present them in charts and diagrams.

Qualitative is something you can't measure - an experience or an observation (from Quality) - such as an opinion
Quantitative can be measured (from Quantity)- such as amount

quantitative is a measurment of amounts(quantity) while qualitative is the detailed analysis of procedures leading to results.

for qualitative, i would say it's hot here in my place...for quantitative...its about 34 degrees Celsius here in my place...

A quantative observation uses numbers. E.g. it takes 10ml of water to dissolve 3g of salt. Whereas a qualative answer would be explaining it without numbers. E.g. when i put salt in water, it dissolves.

Look it up. It's not that hard to find, and it's better than copying someone else's answer to complete your summer school homework.
