Exam 13: Experimental Design

Predict the outcome of the confirmation run for a four factor larger-the-better experiment with an overall average of 18 for the data below: A B C D Level 1 20 15 25 18 Level 2 10 13 19 14

Given the following ANOVA determine the percent contribution at the 0.05 level for F table values of 1/2 = 18.5, 1/3 = 10.1, and 1/4 = 7.71. Source df SS 1 10 1 110 1 175 1 20 1 80

Using inferior-grade, low cost components, and raw materials in the design process is referred to as:

A range or band that the true value is presumed to occur is referred to as a(an):

Repetition is defined as:

Six samples of a quality characteristic give an average of 5.0 and a variance of 0.4. If the loss is $8.00 at a characteristic value of 6.0, what is the loss equation for smaller- the-better? What is the average loss?

The concept of signal to noise was developed by:

A technique to compare the F value of the factor/level with a F distribution value is called:

A new process is developed to reduce the number of defects. Three tests are made with results of 2, 4, and 1 defects. Determine the S/N and compare with a dB value for the existing process of -1.356.

Given three two-level factors and two suspected interactions, determine the degrees of freedom and the OA?

A balanced experiment is efficient-it is called:

The process of selectively upgrading components to eliminate excessive variation is called:

Taguchi's loss function:

The t test is used when:

A simple method of working with interactions is:

The primary goal(s) of a designed experiment are(is) to:
