The time it took for each person to catch the ruler is shown in the table. How can you improve this experiment to make the results more reliable?
repeat the test 5 times and then take and average
repeat the test twice
repeat the test once
change the ruler
Choose TWO variables that are most important to control in order to make sure the test is fair?
keep the same temperature
keep the same starting position
keep the same timer
keep the same weight of the ruler
