A Pharma company is designing an experiment to test 4 different tablet’s ingredients to reduce dissolution time. Each ingredient will be tested at 10 mg and 30 mg. Factors and levels respectively are as follows...

In DOE terminology, the variation that occurs in the response variable beyond that accounted for by the factors is called as...
- Error
- Result
- Setting
- Treatment
This is the simple effect of a factor on a dependent variable. It is the effect of the factor alone averaged across the levels of other factors.
- Main effect
- Interaction effect
- Response
- Result
This is the variation among the differences between means for different levels of one factor over different levels of the other factor.
- Interaction effect
- Response
- Main effect
- Result
Which of the following terms best describes an interaction effect?
- The effect of one independent variable depends on the level of another independent variable.
- The effect of one independent variable on the dependent variable.
- Eliminating any differential influence is of extraneous variables.
- Sequencing effect that occurs from the order in which the treatment conditions are administered.
In an experiment, testing the effect of age on efficiency, the researcher tests three samples of students, A (18-20 yrs), B(25-28) and C (30-32). Each group also comprises 10 men and 10 women. There is a prediction to be made, that women in Group B are more efficient than men in Group A. What kind of effect is being predicted?
- Interaction effect
- Main effect
- Interaction effect and main effect both
- Two main effects
The principle disadvantage of fractional factorial experiment is (that)...
- effects are confounded.
- experimental error is high.
- robustness.
- measurements are less precise.
In resolution III fractional factorial design, main effects are confounded with...
- two factors interaction.
- one factor interaction .
- three factor interaction .
- four factor interaction.
In resolution V fractional factorial design, main effects are confounded with...
- four factor interaction.
- one factor interaction.
- three factor interaction.
- two factors interaction.
It occurs when using fractional factorial designs when factors or interactions are not distinguishable from one another. It is known as what?
- Confounding
- Interaction
- Resolution
- Replication
An experiment has 7 factors with 2 levels each. The experiment has 8 runs. This experiment design is called...
- Fractional factorial design
- Full factorial design
- Half factorial design
- Interaction
Which of the following is possible in a factorial design with two independent variables?
- All of the mentioned are possible.
- There is only one main effect present.
- There are two main effects present
- There are two main effects and an interaction effect present.
It is very cumbersome and involvement of time and money is more if numbers of experiments are more (say 243) for full factorial. What will you do to overcome this difficulty?
- Either of the previous two options can be exercised.
- Try to reduce the factors and levels by process knowledge.
- Conduct a fraction factorial experiment rather than a full factorial experiment.
- Cannot take chances, need to carry out all experiments.
A systematic series of tests in which various input variables are directly manipulated and the effects on the output variables are observed. It is called as...
- DOE
- ANOVA
- Trial and error
- Response
An oil company is designing an experiment to test 3 different oil ingredients to increase the oil viscosity. Each oil ingredient will be tested at 2 levels. Factors and levels and experiment run on full factorial DOE respectively are as follows...

- 6, 3 and 2
- 2,3 and 6
In DOE, when entire set of experiment runs are repeated it is called as...
- Replication
- Repetitions
- Randomization
- Precision
In DOE, repetition of one run of an experiment is called as...
- Repetition
- Replication
- Randomization
- Precision
A farmer is designing an experiment to test 3 different types of seeds of wheat to increase its crop yield; We can say quality of seeds and yield respectively as...
- Independent and dependent variables
- Dependent and independent variables
