Slide 6: Ruler drop. A student holds a ruler between her thumb and index finger, suddenly releases it, and then fast as possible captures it again, measuring the distance it has dropped. The table below shows her results for distance in meters as she repeats it four times. Find her average response time, and the standard deviation. Drop distance (m) Average Response Time: t=.24 seconds 0.28 Standard Deviation: .01 seconds 0.24 0.30 0.31
