Question

Favorite Skittles Flavor?

A poll sampled 93 people, asking them their favorite skittle flavor by color (green, orange, purple, red, or yellow). A separate poll sampled 113 people, again asking them their favorite skittle flavor, but rather than by color they asked by the actual flavor (lime, orange, grape, strawberry, and lemon, respectively). The table below shows the results from both polls. Does the way people choose their favorite Skittles type, by color or flavor, appear to be related to which type is chosen?

	Green (Lime)	Orange	Purple (Grape)	Red (Strawberry)	Yellow (Lemon)
Color	26	13	20	18	16
Flavor	18	21	25	36	13
