sample size
This term is primarily used in scientific, medical, and sociological research to describe the quantity of data points used for analysis. It carries a strong connotation of validity; a small sample size is often viewed as a limitation or a source of potential bias, while a large sample size suggests a more robust and generalizable result.
In professional academic writing, it is typically paired with adjectives like "sufficient," "adequate," or "insufficient" to indicate whether the data set is strong enough to support the study's conclusions. It is a technical term and is rarely used in casual conversation unless discussing a specific study or poll.
