Terry's average score in basketball is best represented by a ratio measurement. This classification is appropriate because ratio measurements have all the characteristics of interval measurements but also include a true zero point, which allows for the full range of mathematical operations.

In the context of Terry's average score, a score of zero would indicate the complete absence of scoring, which is a meaningful zero in terms of basketball performance. Moreover, scores can be meaningfully compared using multiplication and division, such as stating that Terry scored twice as much as another player, which is only possible with ratio measurements.

This distinguishes it from nominal measurements, which categorize data without a specific order or quantity, ordinal measurements that provide a ranking but lack a defined distance between ranks, and interval measurements that have equal distances between values but do not have a true zero point. Thus, the ratio level of measurement is the most accurate description of Terry's average score.
