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:
