What are the advantages of a Factorial Design?

Selecciona una de las siguientes respuestas posibles:

  • Less time consuming, effective, ethical

An interaction occurs when:

Selecciona una de las siguientes respuestas posibles:

  • One IV interacts with another IV when the effects of one IV are different depending on which level of the other IV is being considered and One IV interacts with another IV when it changes the impact of another IV on the DV

Factorial experiments allow researchers to:

Selecciona una de las siguientes respuestas posibles:

  • Combine each treatment’s main effects to see the overall effect they have in a study

  • Contrast the average of these main effects to determine if the treatment has one effect on one group of participants and another effect on another group of participants

  • A and B.

Explicación

1

Main effect is isolating one factor and examining the effect of this factor on the DV

Selecciona uno de los siguientes:

  • VERDADERO
  • FALSO

Explicación

Pregunta 12 de 14

1

In Factorial designs, you compare one treatment’s main effects with another treatment’s main effects and if one factor differs significantly at discrete levels of the other factor we have an interaction.

Selecciona uno de los siguientes:

  • VERDADERO
  • FALSO

Explicación

Pregunta 13 de 14
