True Score

What is True Score?

The true score represents the central tendency of the distribution derived from including all users within a user population. It is often only ascertainable when the user population is relatively small. In most instances, the true score is estimated based on the observed score obtained from a sample of the population.

Why is True Score Important?

  • Accurate Representation: The true score serves as a reliable representation of the central tendency of a user population’s distribution, providing valuable insights into overall performance or behavior.
  • Estimation Benchmark: When direct measurement of the true score is impractical due to large populations, it serves as a benchmark against which observed scores from samples are compared, aiding in inference and estimation.
  • Sample Generalization: By estimating the true score from sample data, researchers can generalize findings to the broader user population, facilitating broader applicability of research outcomes.
