This second RA does not know if the chair in the room is comfortable or uncomfortable. Finally, participants are unaware that the experiment has two different chair conditions. Results showed higher anger scores from participants in the uncomfortable- chair condition than participants in the comfortable-chair condition. An independent-samples t test confirmed this difference to be statistically sig nificant, t(58) = 3.24, p < .05. The results are shown in Figure 1. Figure 1: Results from Veremund's experiment. Mean Anger Responses in a Function of Chair 2. Neither participants nor the interviewer knew what condition each participant was in. What is this design called? Why is it used? 3. Can Veremund conclude that chair comfort caused changes in survey scores? Please answer this question with reference to the three criteria for 3 MacBook Air 2/4 I To answer Questions 2 and 3, please use the information from the follow- ing vignette. Veremund is a quantitative psychologist interested in whether survey re- sponses are affected by physical comfort. He obtains a survey that measures people's disposition to anger. Previous studies have shown that the survey is high in construct validity., Scores on the survey range from 0 to 10, with higher scores indicating greater disposition to anger. Veremund wants to know whether people's responses will be higher if respondents are sitting in an uncomfortable chair compared to a comfortable chair. Veremund recruits 60 participants for his study. They are randomly as- signed to one of two conditions: a comfortable-chair condition and an uncomfortable- chair condition. The two chairs are identical in appearance, but the seat of the uncomfortable chair is considerably harder than the seat of the comfort- able chair. Veremund administers the survey verbally, asking participants to rate their agreement with a number of statements. Veremund interviews each participant through an intercom system; in this way, he is unable to see each participant, know whether they're con- stantly shifting their position, and so on. He does not know whether any given participant he is interviewing is in the comfortable- or uncomfortable- chair condition. Veremund has two research assistants (RAs) helping him with the study. One RA flips a coin before each participant arrives at the lab. If it lands on heads, the uncomfortable chair is placed in the room; if it lands on tails, the comfortable chair is placed in the room. The other RA is 2 MacBook Air F10 OOD 000 F9 F4 F5 F6 F7 F8
