7. Jason carried out an experiment on the effects of leading questions on the accuracy of eyewitnesses’ recall. He interviewed one group of participants who had five leading questions in their interview (Condition 1). The other group of participants had no leading questions in their interview (Condition 2). Jason’s results are in Table 2. Calculate the mean score for Condition 1 and the mean score for Condition 2 and complete Table 2 with your answers to two decimal places. (b) Describe how Jason could use the findings of his study to improve eyewitness testimony.

Step 1

Calculate the mean score for Condition 1

Answer

To calculate the mean score for Condition 1, we can use the formula for the mean:

$\text{Mean} = \frac{\text{Total of incorrect answers}}{\text{Number of participants}}$

The total number of incorrect answers for Condition 1 is 39. Since there are 12 participants (from the 8 responses provided):

$\text{Mean}_{C1} = \frac{39}{12} = 3.25$

Thus, the mean score for Condition 1 is 3.25.

Step 2

Calculate the mean score for Condition 2

Answer

Similarly, for Condition 2, we again apply the mean formula:

The total number of incorrect answers for Condition 2 is 16, with 12 participants:

$\text{Mean}_{C2} = \frac{16}{12} = 1.33$

Therefore, the mean score for Condition 2 is 1.33.

Answer

Jason's results indicate that leading questions can significantly increase the number of incorrect answers given by witnesses ( Condition 1). To improve eyewitness testimony, Jason could suggest that police officers avoid leading questions during interviews. Instead, they should use open-ended questions which may result in more accurate recall of events by the witnesses.
