19. if a scientist needs to use a large dataset to explore how corn grows in different soils, how would this data be classified?
a. quantitative
b. qualitative
c. descriptive
d. mixed methods

ANSWER:

The correct option is B- Qualitative.

EXPLANATION:

When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.

Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
