Explanation:

Identify the definition

The question asks for the term that describes a subset of a population used to make predictions about that population.

Evaluate the options

• sample: A sample is a representative subset of a population selected for analysis.
• mean: The mean is a measure of central tendency (average), not a subset.
• cluster: A cluster is a specific type of subgroup used in cluster sampling, but the general term for any subset used for predictions is a sample.
• standard deviation: This is a measure of data dispersion, not a subset.

Select the correct term

The correct term that fits the definition is "sample".

Answer:

• sample. (Correct answer)
• mean.
• cluster.
• standard deviation.
