Final answer:
Emic instruments are not culture-free and are developed to understand a culture from the perspective of the people being researched. Etic instruments, on the other hand, are constructed to measure a particular factor for each nationality.
Step-by-step explanation:
Anthropologists aim to observe and study cultures without bias, and they use two different perspectives to achieve this: emic and etic perspectives. Emic instruments are not culture-free and are developed to understand a culture from the perspective of the people being researched, considering their beliefs and standards. On the other hand, etic instruments are constructed to measure a particular factor for each nationality and may not fully capture the nuances of a specific culture.
