Research MethodsI Experimental Brief 1 Dr. Green wishes to test if music has an effect on reaction time. She posits that different types of music will have varying effects on participants that will ultimately affect their reaction time. She has the participants in three conditions; No music, Classical music, and Rock music. In each condition, the participants have to grab a dropped ruler as fast as possible. Dr. Green recorded the average number of centimeters for each participant and recorded the following data. Participant 1 Participant 2 Participant 3 Participant4 No Music 10.5 cm 5.2 cm 7.8 cm 15.1 cm Classical 8.7 cm 5.0 cm 6.2 cm 10.2 cm Rock 11.0 cm 6.1 cm 8.2 cm 16.1 cm a. What are the two variables that are being measured in this study? 2. b. How are both variables operational defined? 1. 2.

Explanation / Answer

a.
1. Effect of music on participants
2. Effect of music on reaction time

b.
1. How fast the participants grab a dropped ruler
2. Average number of centimeters for each participant

c.
1. Are the participants able to solve a given puzzle in specified time limit?
2. The time in which the participants able to solve a given puzzle in three different types of music to measure the reaction time.

d.
No music Mean = 9.65 Median = 9.15
Classical music Mean = 7.525 Median = 7.45
Rock music Mean = 10.35 Median = 9.6

e.
No music Variance = 17.88 SD = 4.23
Classical music Variance = 5.56 SD = 2.36
Rock music Variance = 18.72 SD = 4.33
