Controlled Study Data Set Who: Pendulum What: Number of oscillations When: January 2005 Where: In my apartment Why: To analyze the relationship between the angle at which I start the pendulum and the number of oscillations. How: Using a 30cm long string, a washer, and a protractor, I created my pendulum. My independent variable is the angle at which I released the washer. Then I measured how many oscillations occurred before the washer came to a stop. Number of observations: 7 Variable Names: Angle: The angle at which I released the washer measured in degrees Trial1: Number of oscillations from first trial Trial2: Number of oscillations from second trial Trial3: Number of oscillations from thrid trial With this data set, we can get a association between oscillations and the angle at which the pendulum was released. This can further be analyzed to see what kind of affect gravity is playing in the study.
