An Experiment Was Done to Compare the Effect of Having $\chi$

question 13

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.

• A)The output shows that the assumption of sphericity has been violated, \(\chi\)² (2) = 0.81, p = .17.
• B)The output shows that the assumption of sphericity has been violated, \(\chi\)² (2) = 3.58, p > .05.
• C)The output shows that the assumption of sphericity has been met, \(\chi\)² (2) = 0.81, p > .05.
• D)The output shows that the assumption of sphericity has been met, \(\chi\)²(2) = 3.58, p = .17.
