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.

Design of Experiments Quiz Questions with Answers

• Why is randomization an important aspect of conducting a designed experiment?
• Why would an agricultural field trial require a different experimental strategy than a typical industrial experiment?
• Sir Ronald A. Fisher is regarded as the modern pioneer of designed experiments because
• The analysis of variance treats the factor as if it were qualitative even if it is a continuous variable such as temperature.
• The Fisher LSD procedure used to compare pairs of treatment means following an ANOVA is extremely conservative.
• If a single-factor experiment has a continuous factor with $a$ levels and a polynomial of degree $a – 1$ is fit to the data the error sum of squares for the polynomial model will be identical to the error sum of squares that resulted from the standard ANOVA.
• In a single-factor random effects experiment we assume that the levels of the factor are selected at random from an infinitely large population of possible levels.
• When comparing more than two population means at the same time we should not use:
• In an independent samples t-test two samples:
• When population variance is unknown and sample sizes are small we can estimate the variance by
• To apply the t-test, two samples must be:
• The t-test is used when:
• Paired samples are:
• A paired samples t-test is also called:
• Paired samples t-test utilizes degree of freedom:
• In case of pairing, samples are usually taken from:
• Basic ANOVA measures ————— source/s of variation
• ANOVA is suitable to compare —————- means
• In ANOVA we use
• For the validity of different inferential tools we assume that errors have:
