Step 1
Step 2
Draw a suitable graph to represent the results shown in Table 3.
Answer
A bar chart should be created to illustrate the mean score (out of 7) for the intensity of crying of one-year-olds after their mother leaves them in a playroom. The x-axis should represent the two conditions (Condition A and Condition B), while the y-axis should indicate the mean score for the intensity of crying. Each bar should clearly label its respective condition, and the title should be appropriate for the context.
Step 3
Compare independent groups and matched pairs experimental/research designs as used in child psychology.
Answer
Both independent groups and matched pairs designs involve different participants in each group, but they differ in their methodology.
-
In an independent groups design, participants are randomly assigned to various conditions, which may introduce variability between groups due to individual differences.
-
Conversely, matched pairs designs involve pairing participants based on shared characteristics (like age, gender, or pre-existing abilities), which helps control for potential confounding variables. However, it may be more time-consuming and complex to implement.
In summary, the main similarity is that both designs control groups that differ on measured outcomes, while the key difference lies in how participants are assigned to conditions.
