Field and Lawson (2003) reported the effects of giving children aged 7–9 years positive, negative or no information about novel animals (Australian marsupials). This variable was called ‘Infotype’. Each child received all three types of information about different animals. The gender of the child was also examined. The outcome was the time taken for the children to put their hand in a box in which they believed either the positive, negative, or no information animal was housed. Which of the following is the most appropriate method to analyse their data?

Answer choices

  1. One-way independent ANOVA
  2. One-way repeated-measures ANOVA
  3. Two-way mixed ANOVA
  4. Two-way independent ANOVA

Answer: Two-way mixed ANOVA

A researcher tested 40 children aged 6 years.

Answer choices

  1. A repeated-measures design
  2. A matched design
  3. A mixed design
  4. A between-subjects design

Answer: A between-subjects design
