Which combination of factors is most likely to produce a significant value for an independent-measures t statistic?

One sample has a variance of s2 = 10 and a second sample has a variance of s2 = 6.  If the two samples have the same number of scores, what is the pooled variance for the two samples?

In analysis of variance, what is a factor?

An independent-measures study comparing two treatment conditions produces a t statistic with df = 18.  If the two samples are the same size (n1 = n2), how many participants were in each of the samples?

For a two-factor study with 2 levels of factor A, 2 levels of factor B, and a separate sample of 10 participants in each treatment condition, what is dfwithin treatments?

A researcher studies the number of dogs in an average household in Wisconsin. The number of dogs is an example of a(n) _________ variable.
