A fractional factorial experiment is designed at 2 levels for 8 factors with a maximum of only 128 runs possible. This could be a

OPTIONS

• Quarter Fractional Factorial Design
• Screening Design
• Half fractional Factorial Design
• Resolution IV design

ANSWER

HALF FRACTIONAL FACTORIAL DESIGN

EXPLANATION

For 8 factors and 2 levels, full factorial experiment would have resulted in 256 runs, so here with 128 runs, Half fractional Factorial Design is correct.
