Which of the following is an important advantage of a repeated-measures ANOVA design?

Selecciona una de las siguientes respuestas posibles:

  • A different sample of participants serves in each condition, making it possible to compare different populations

  • Individual differences do not contribute to unsystematic variance

  • A large number of participants is generally required, which provides a better glimpse of the population
