What was the mean age of participants in Dixon et al's study?

  1. 24.5 years

  2. 25.2 years

  3. 26.0 years

  4. 27.3 years

The correct answer is: 25.2 years

The mean age of participants in Dixon et al's study being 25.2 years indicates that this figure represents the average age calculated from the ages of all participants involved in the research. The researchers would have gathered age data from each participant, summed these ages, and then divided by the total number of participants to arrive at this mean. This age information is often relevant in psychological studies because it can provide context regarding the demographic characteristics of the sample, potentially influencing the study's results and their applicability to different populations. Understanding the average age helps readers gauge whether the findings may be more relevant to younger or older individuals and can, therefore, influence the interpretation of the study's implications in real-world settings or future research.
