What is the meaning of quantitative in science?

Quantitative means measuring a quantity – putting a value to something. For example you might measure the rate of a reaction by seeing how many seconds it takes for a change to happen such as a piece of magnesium ribbon to dissolve in acids of different concentrations. Qualitative means without determining a value.
