Exercise 2.5 [22 factorial design]

EXERCISE 2.5

1. Below is given the plan and yields of 22-factorial experiment involving 2 factors N and S each at two levels 0 and 1. Analyse the design.

2. The following data are obtained from a 22 factorial experiment blocked 3 times. Evaluate the sum of squares for all factorial effect by the contrast method. Draw conclusion.

3. The following data are obtained from a 22 factorial experiment replicated three times. Evaluate the sum of squares for all factorial effects by contrast method. Draw conclusions.

4. Given the following observations for two factors A & B at two levels To compute the main effects and analyse the variance.lude

5. From the following data, evaluate the sum of squares of all factorial effects by contrast method and draw conclusions using 0.05 level of S significance.

6. The following data represents the results of a 22 factorial design with 2 factors and 2 levels each with four replications. Analyse the data for response.
