Summers et al (2021) hypothesised that people believe that pain is influenced by socio-economic status (SES); specifically, that low SES individuals are believed to be less sensitive to pain. To test their hypothesis, they had participants read a description of a target person (accompanied by a random photo) that included several cues to SES (education, job, income, neighbourhood) and to estimate target's pain sensitivity to injuries on the Pain Sensitivity Scale. Half of the participants read descriptions of low-SES individuals, and half read descriptions of high-SES individuals. After conducting the original study, they ran a follow-up study to determine whether the effect generalises to medical professionals. They repeated the study, but with two groups of participants - medical professionals and undergraduate students. All other aspects of the study were the same. Which of the following statements is true about this study (select all that apply)? a. Results should be analysed in a factorial ANOVA b. It uses a quasi-experimental design c. It has better internal validity than the original study d. It has better external validity than the original study
