What type of data is identifying where the barnacle is found on the boat? (Quantitative or qualitative). Why?
attashe74 [19]

Answer:

qualitative

Explanation:

<u>Identifying where the barnacle is found of the boat will result in qualitative data, rather than quantitative.</u>

Qualitative data has to do with attributes that cannot be measured but can only be observed, approximated, and characterized, Examples include presence/absence, beautiful/ugly, black/white, etc. On the other hand, quantitative data has to do with attributes that can be measured, such as height, number of leaves, etc.

<em>Identifying where the barnacle is found on the boat has nothing to do with measurement. It only has to do with recording the presence or absence of barnacle in various locations on the boat. Hence, it is qualitative data.</em>
