Design of Experiments Quiz with Answers

• If an interaction effect in a factorial design is significant the main effects of the factors involved in that interaction may be difficult to interpret.
• Factorial experiments cannot be used to detect the presence of interaction.
• An interaction term in a factorial model with quantitative factors introduces curvature in the response surface representation of the results.
• A factorial experiment can be run as an RCBD by assigning the runs from each replicate to separate blocks.
• One of the ANOVA assumptions is that treatments have:
• For ANOVA we assume that treatments are applied to the experimental units:
• One factor ANOVA means, there is only:
• For one factor ANOVA, the model contains:
• Single-factor ANOVA is also called:
• In a fixed effect model:
• In a random effect model:
• The treatment effect is associated with:
• If the experiment were to be repeated and the same set of treatments would be included, we choose:
• The experimenter is interested in treatment means only. The model used is called:
• A fixed effect model is used when the effect of —————– is assumed to be fixed during the experiment.
• A researcher is interested in measuring the rate of production of five particular machines. The model will be a:
• To compare the IQ level of five students a series of tests is planned and IQ is computed based on their results. The model will be:
• If the treatments in a particular experiment are a random sample from a large population of similar treatments. we choose:
• If the experimenter is interested in the variation among treatment means not the treatment means themselves. The model used is called:
• In a random effects model ————- are randomly chosen from a large population.
