Quantitative data includes numbers while qualitative data includes descriptions. Since this includes a numerical value it would be considered quantitative.
If we are comparing the densities of water and mercury in a qualitative manner, then we could make a statement such as "mercury is more dense than water". It doesn't specifiyhow muchmore dense.
We tend to classify data as either quantitative or qualitative, but not both as qualitative information can be inferred from the quantitative results. The mass of sample A is 10.0 g; the mass of sample B is 10.0 g. These are quantitative results but they infer that the mass of sample A is bigger than B (qualitative comparison).
