Which one is for measuring qualitative or quantitative?

Answer 1

A qualitative measurement is just that- it measures the quality of something, or rather it's more of a physical observation.

So say you were observing a sunflower.

Yellow would be a qualitative measurement.

The texture of the petals(smooth).

All things that would qualify as sort of observations. Qualitative "measurement" actually uses no numbers at all.

Answer 2

This is a contradiction in terms. If something is qualitative you essentially don't measure it. If you measure, you are doing something quantitative.

An example of the difference is in chemical analysis. Qualitative analysis means to find out what something is, e.g. testing a food with iodine to see if there is starch present. Quantitative analysis measures how much of a substance you have, for instance doing a titration to measure the amount of acid in a solution.

Answer 3

they are measurements that have no numerical value, for example telling when a particular solution turns a different colour. It is often seen as being far less accurate than quantative measurements due to the human error involved.

A qualitative measurement is a type of chemical analysis which determine only the components in a compound or mixture, not the concentration of these components.

Examples: Lactose in milk

- qualitative: determination only of the presence of this sugar in milk, with an adequate test.

- quantitative: determination of the concentration of lactose in milk, expressed in % or g/L.

Answer 4

Qualitative analysis: identification of an element, ion, substance but without an evaluation of the concentration.

Answer 5

Something that can be objectively and definitively measured like distance, mass, or temperature.

Answer 6

- test of chlorine in water

- test of sodium in a mixture by flame test

- test of hydrogen sulphide in a gas mixture

Answer 7
