This graph has a negative trend because the different pumpkins have different height, mostly regular sized pumpkins while some students brought tall ones

Circumference

This graph has no trend since more rubber bands would be needed if there is a smaller circumference because of the rubber bands not stretching far, would of build enough pressure for the pumpkin to explode

The internal diameter has no trend because like the diameter of the pumpkins, they share the same size and shape in the inside

The rind graph has no trend, no matter how much rubber bands you use, the rind thickness doesn’t really change, but depends on the size of the pumpkin
