Answer:
population size of red-tailed hawks
Step-by-step explanation:
Data, which is how observations made in an experiment are represented, are of two types namely: quantitative and qualitative data. Qualitative data is the type of data that involves the description of something in an experiment based on quality or trait.
However, on the other hand, QUANTITATIVE DATA has to do with numerical observation i.e. numbers and digits are used to represent an information. For example, in this question, POPULATION SIZE OF RED-RED-TAILED HAWKS, is a quantitative data because it gives a numerical representation (population size) of an information.
