A factorial experiment was conducted to understand the impact of 4 inputs on the flex rate of a product in pounds per inch (the response variable). The goal was to increase the flex rate of the product. The inputs are: Factor A: Formulation (formulation 1 or formulation 2), Factor B: Cycle time ( 15 seconds or 25 seconds), Factor C: Pressure ( 300 psi or 375 psi) and Factor D: Temperature ( 110 degrees F or 130 degrees F).

Factor A	Factor B	Factor C	Factor D	Response
1	15	300	110	71
2	15	300	110	73
1	25	300	110	74
2	25	300	110	76
1	15	375	110	78
2	15	375	110	78
1	25	375	110	77
2	25	375	110	79
1	15	300	130	70
2	15	300	130	71
1	25	300	130	75
2	25	300	130	75
1	15	375	130	78
2	15	375	130	78
1	25	375	130	74
