An Experiment Was Done to Compare the Effect of Having

question 17

Multiple Choice

An experiment was done to compare the effect of having a conversation via a hands-free mobile phone,having a conversation with an in-car passenger,and no distraction (baseline) on driving accuracy.Twenty participants from two different age groups (18-25 years and 26-40 years) took part.All participants in both age groups took part in all three conditions of the experiment (in counterbalanced order) ,and their driving accuracy was measured by a layperson who remained unaware of the experimental hypothesis. Which of the following sentences is the correct interpretation of the interaction between distraction and age?

• A)The age of the driver almost significantly interacted with the type of distraction,F(2,36)= .36,p = .055.This effect tells us that profile of ratings of driving accuracy across the different types of distraction might have differed in the age groups.
• B)The age of the driver did not significantly interact with the type of distraction,F(2,36)= 1.05,p = .36.This effect tells us that profile of ratings of driving accuracy across the different types of distraction was similar for both age groups.
• C)The age of the driver significantly interacted with the type of distraction,F(2,36)= 45.95,p = .001.This effect tells us that profile of ratings of driving accuracy across the different types of distraction was different in the two age groups.
• D)The interaction between age group and distraction group yielded a large effect.
