What does ANOVA stand for?

• Analysis of Value

• AssessmeNt of Validity

• Analysis of Variance

• Assessment of New Variability

It is the ratio of the mean squares treatment to the mean squares error

• F-stat

• t-stat

• chi-square

• r

The larger the F-statistic, the greater the variation between sample means relative to the variation within the samples.

• True

• t-test

• Pearson's r

If the groups come from a single population (e.g., measuring before and after an experimental treatment), perform a __________ t-test.

If there is one group being compared against a standard value (e.g., comparing the acidity of a liquid to a neutral pH of 7), perform a __________ t-test.

If |t stat| < t crit, reject the H0.

• True

• False

If |F stat| > F crit, reject the H0.

• True
