Question

Which of the following will lead to a larger calculated F ratio (all else remaining constant)?

		larger variances within each of the samples.
		reduced separation of the population means.
		larger sample sizes.
		a larger alpha level.

A researcher who uses the chi-square test and wants to obtain statistically significant results would like the squared differences between the observed frequencies and the expected frequencies to add up to:

		zero
		1.0
		as large a number as possible
		N

In the two-group case, the F ratio for the one-way ANOVA equals:

		the square-root of the corresponding t value.
		the square of the corresponding t value.
		one-half of the corresponding t value.
		twice the corresponding t value.

In a one-way ANOVA, eta squared is:

		an unbiased estimate of omega-squared.
		the proportion of variance in your samples accounted for by group membership.
		SSbet divided by SSw.
		all of the above.
