Answer: naturalistic observation
Explanation: Naturalistic observation is a technique used in the study of subjects in their natural habitat without any manipulation or interference from the observer. The aim of naturalistic observation is to describe in detail the behaviour of an organism in their natural setting, situation or habitat.
Conducting a naturalistic observation offers some advantages which include:
I) allowing investigation of behaviours that occur in complex social settings.
II) allowing the researcher to gather qualitative as well as quantitative data and
III) allowing the development of theories based on collected observations etc.
However, it is less useful in studying well-defined hypotheses under precisely specified conditions since they are typically designed not to confirm previously formed hypotheses.
The Egyptians used a weird method to reduce friction by pouring water onto the sand, causing the sand to clump together and make it easier to pull along due to the reason that each individual piece of sand doesn't hold it back. They called this weird technique capillary bridges.
Answer:
option A
Explanation:
The correct answer is option A
A population is under-represented when it is proportionally smaller in a sample than in its population.
For population representation of any community, if the sample size of the population of the community is not in accordance means not in the same ratio as it is actually present then that community is under-represented.
