Which of the following refers to a sampling approach in structured observation whereby a sampled individual is observed for a set period of time?

Correct option is A

Focal sampling is a sampling approach in structured observation where a particular individual (the focal subject) is observed for a set period of time. This method is commonly used in behavioral studies to focus on one individual within a group for detailed observation.
Information Booster
· Focal sampling is a method used in structured observation, where an individual is selected as the focus of observation for a specific, predetermined period. This approach is particularly effective in behavioral research, where detailed and continuous monitoring of a single subject is required to understand their actions and interactions.
· This method allows researchers to:
1. Record detailed behavior patterns of the focal individual.
2. Monitor changes over time, such as responses to stimuli or environmental changes.
3. Avoid bias that can occur when trying to observe multiple individuals simultaneously, ensuring focused and accurate data collection.
Additional Information
· (b) Snowball sampling: Incorrect, as snowball sampling is used for recruiting participants through referrals, not for structured observation.
· (c) Purposive sampling: Incorrect, as this refers to the intentional selection of individuals based on study criteria, not the method of observation.
· (d) Cluster sampling: Incorrect, as cluster sampling involves selecting groups (clusters) rather than individuals for observation.
