Step 1
Step 2
Draw a suitable graph to represent the results shown in Table 3.
Answer
A bar chart should be created to display the mean score (out of 7) for the intensity of crying after the mother leaves a one-year-old in a playroom. The x-axis should represent the two conditions (Condition A and Condition B) and the y-axis should indicate the mean score for the intensity of crying. Each bar should be labeled appropriately with the respective mean scores of 5 for Condition A and 3 for Condition B.
Step 3
Briefly describe an independent groups experimental/research design.
Answer
In an independent groups design, different participants are assigned to each condition of the experiment. This means that individuals in one condition are not the same as those in another condition. A significant advantage of this design is that it minimizes the effects of participant variables. However, it requires a larger sample size compared to other designs, as each participant can only partake in one condition.
Step 4
Describe the similarities and differences between independent groups and matched pairs experimental/research designs as used in child psychology.
Answer
Both independent groups and matched pairs designs aim to compare different conditions in an experiment. A key similarity is that both designs utilize different participants in each condition. However, the main difference lies in how participants are assigned: independent groups use completely different participants for each condition, while matched pairs involve pairing individuals based on specific characteristics (e.g., age, ability) and then randomly assigning each member of the pair to different conditions. This reduces variability in results related to participant characteristics in matched pairs designs.
