What is the best way to record and interpret data from an experiment measuring the distance a car traveled down a ramp from different heights?
A. Measure how far the car travels each time
B. Measure how far the car travels each time and the height of the ramps.
C. Average the distance traveled at all trials at each position.
C - Averaging the data from the trials will give us the best information about how the car traveled at each ramp height.
