Experiment 1:
A researcher conducts an experiment to study reflex times and the integration of several sensory processes. In the study, participants have to catch a ball that has been dropped. As an approximation for reflex "speed", researchers measure how far the ball falls before the participant catches it. The data in Table 1 is obtained:
Participant
7. What can be concluded from this data:
A. Reaction time is positively correlated with age and positively correlated with trial number.
B. Reaction time is positively correlated with age and negative correlated with trial number
C. Reaction time is negatively correlated with age and positively correlated with attempt number.
D. Reaction time is negatively correlated with age and negatively correlated with attempt number.
I don't know the answer, and find myself getting confused.
My instructor says the answer is D, but I'm pretty sure it is the exact opposite. Can you explain what your answer choice is?
