Procedure 1. The table below is a data set of an experiment. This is the time it takes a marble to roll down an inclined plane 3 meter long. Distance Time 1 (s) Time 2 (s) Time 3 (s) Time 4 (s) Time 5 (s) 3m 1.5 1.6 1.4 1.7 1.3 2. Plot the graph of these values 3. Find the average of the time you have in your data. 4. The mean or the average of the time is the measured value. Questions 1. Did your time value follows a straight line when plotted? Why not? 2. Why is there a need to get the average of these time values?
