Question

Design a full-factorial experiment.* Use one response and at least 2 factors, each factor with at least 2 levels.

a. Describe the response and factor variables (e.g., what type of data are they, what are their levels or value ranges).

b. What is the unit of observation?

c. Describe the population, the sampling technique (how will you ensure random selection of units), and the sample and cell (treatment combinations) sizes.

d. Will you have replications or repetitions?

e. Are there any blocking factors?

f. Graphically show the design and explain it (similar to pages VII 81-86).

g. How will you ensure random assignment of units to the treatment groups?

h. How will you ensure random order of experimental runs?

i. What are the environmental or noise factors?

Answer #1

Here we are designing 2^{4} full factorial
experiment.

Here, Response = 0 and 1

factor variables = A, B, C, D

**Example
:**- suppose our experiment is to determine the
effect of a special diet and drug on cholesterol level.

=> let , A = drug effect

B = special diet

hence we are havinf 4 possible combination.

A_{0}B_{0} = A group without drug and without
diet.

A_{1}B_{0}= A group with drug and without
diet.

A_{0}B_{1}=A group without drug and with
diet.

A_{1}B_{1}=A group with drug and with diet.

a) here response = 0 and 1 and factor A anb B

c) the sample selection is simple random sampling with replications. the 2 treatments are A and B.

the treatment combinations are 4.

d) we have replications. we are using SRS with repitation.

Tom designed a complete factorial experiment with 2 factors. One
factor had 4 levels, the other had 5 levels. For each combination
of levels of factors, there were 6 replicates.
A) In the ANOVA table associated with this design, what
were the degrees of freedom of the interaction?
a. 7
b. 12
c. 20
d. 24
e. 30
B) Suppose we want to test the significance of the main
effect of the factor with 4 levels. What is the distribution...

6.Question 6
What is said to occur when the effect of one input factor on the
output depends on the level of another input factor?
1 point
Factors
Blocking
ANOVA
Interaction
7.Question 7
When performing analysis of variance for a single factor
experiment, which of the following is a required assumption?
1 point
Means are equal
Errors are equal
Variances are equal
Sample sizes are equal
8.Question 8
What test statistic is used for ANOVA?
1 point
Chi-square

The foundation of experimental design comes from agriculture.
Here is a typical experiment. You want to study the effect of two
fertilizers, sulfate of ammonia and superphosphate, on the yield of
Brussels sprouts. Each fertilizer is used at four levels: 0, 30,
60, and 90 pounds per acre.
a/ Describe the response variable
b/ Describe the treatments. How many levels for each
treatment?
c/ List a complete set of treatment combinations. Arrange your
list in table form
d/ Suppose you...

A drug made by Company A is used to promote growth in chickens
is being compared to two different generic competitors made by
Companies B & C. The drug at its intended dose can be delivered
to the birds in either feed or in water. Eight different rooms each
containing at least 7 floor pens were used for the study and fifty
1-day-old chicks were placed into each pen on the same day for each
room. Each of the 6...
