10. a geologist is collecting data from a sample of rock. which of the following is an example of
qualitative, rather than quantitative, data?
o a. a description of the rock's coloring
o b. the percentages of various minerals in the rock
o c. the weight of the rock
o d. a measurement of rock's grain size

A "description of the rock's coloring" is an example of "qualitative", rather than "quantitative data".

Explanation:

Data can be categorized as quantitative data when the data exhibits information that is countable or measurable using certain units or numbers. On the other hand, the data can be called qualitative when it describes characteristics that are not measurable and can only be illustrated in non-statistical form. The size of the rock sample, the percentage of minerals in it, its grain size are all measurable, while the coloring is not."
