Final answer:
The classification of habitats as 'wet' or 'dry' is considered nominal data because they are qualitative categories without a quantitative value and are mutually exclusive. The correct answer to the question is 'Yes'.
Step-by-step explanation:
The classification of habitat types as 'wet' or 'dry' would be considered nominal data because these categories are names that do not have an inherent order. Nominal data are qualitative and used to label variables without a quantitative value.
In the context of the question, there's enough information given to determine the answer. The choice between 'wet' or 'dry' habitats creates mutually exclusive groups, as a habitat can typically be classified as one or the other, but not both simultaneously.
Thus, the correct answer to whether the choice of wet or dry habitats is nominal data would be 'Yes'. This question relates to the concept of data types in scientific research, which is crucial when justifying the selection of data needed to answer scientific questions, such as understanding how organisms respond to changes in their external environment.
