Suppose you are testing the relationship between the size of a bowling ball, experience of the bowler, and number of pins knocked over. First, a professional bowls a 5 cm bowling ball and knocks over 1 pin, 3 pins, and 1 pin in 3 different trials. Then, an amateur bowls a 50 cm bowling ball and knocks over 10 pins, 10 pins, and 10 pins in 3 different trials. Thus you conclude that amateur bowlers knock over more pins than professional bowlers. What is wrong with this experiment and what can be done to correct it?

Answer and Explanation:

As the ball size is expanding, it will clear a huge zone so likelihood of hitting increasingly number of pins will increment.

Despite the fact that the expert player is all around polished one, since 5 cm measurement is little he lost to the beginner player as his ball is extremely huge with 50 cm.

All together to have reasonable trial the size of ball ought to be same for the two players.
