What sampling technique and size were used?

Random sampling, 20 chimpanzees Opportunity sampling, 5 chimpanzees paired in mother-child pairs Convenience sampling, 8 pairs Stratified sampling, 10 chimpanzees

Correct Answer:

Opportunity sampling, 5 chimpanzees paired in mother-child pairs

Explanation:

Sampling method is about how participants are chosen. In this study, the researchers used opportunity sampling, selecting chimpanzees that were readily available in the setting rather than drawing from the entire population. They organized the subjects into mother–child pairs, giving five pairs in total. This approach is practical and ethical in animal research, enabling study of maternal relationships with a manageable sample size. A random sample from the whole population would be ideal in theory but isn’t usually feasible in captive or field settings; stratified sampling would require predefined subgroups and a specific sampling plan within them, which isn’t described here.
