Which number of drops happened most often?

• 3

• 11-20

• 17

• 21-30

What was our hypothesis in the drops on coin experiment?

• The 10 kurus coin would hold more drops because it is larger

• The 5 & 10 kurus coins would hold the same number of drops

• The 5 kurus coin would hold more drops because it is smaller

What question did we ask after seeing the average number of drops was the same on each coin?

• Were the size of drops changing?

• Did the 5 kurus really hold the same number of drops.

• Was this a fair test if more than one thing changed?

• All of these
