First you have to have a procedure.Witch is a number of steps that describes how to perform a specific task.Then you do the actual fair test.For example,like we did in class, you can drop two balls at the same time and then you measure the height of how high the ball bounced in centimeters.You have to do this more than once to get the mean data.So you add up all your data then divide by how many numbers there are.For example 20+20=40 then 40/2=20 so 20 would be your mean for one ball then 30+20=50then 50/2=25 so 25 would be your mean for the other ball.Next you subtract 25 by 20 witch is 5.So your conclusion is,on average the ping pong ball bounced 5 centimeters higher than the basket ball.
