What is the difference between quantitative and qualitative observations?
Qualitative refers to what a sample is, while quantitative refers to how much of that material is present. For example, the "squeaky pop test," which involves taking a burning splint and immersing it in a test tube, is a qualitative test. If the gas in the test tube pops, you know you have hydrogen production. In this case, no numbers are being taken - it is only to identify the gas in the test tube. Say you capture the gas released by whatever reaction takes place in the test tube. Measuring the volume of the gas would be the quantitative observation.
