If between-groups variance is large, then we have observed

a) experimenter effects.

b) large systematic variance.

c) large differences due to confounds.

d) possibly both large systematic variance and large differences due to confounds.

QUESTION 3

  1. The larger the F-ratio, the greater the chance that

    a) a mistake has been made in the computation.

    b) there are large systematic effects present.

    c) the experimental manipulation probably did not have the predicted effects.

    d) the between-groups variation is no larger than would be expected by chance and no larger than the within-groups variance.

Answer #1

1. The correct answer is Option A. If between-groups variance is large, then we have observed experimenter effects.

2. The correct answer is Option D. The larger the F-ratio, the greater the chance that the between-groups variation is no larger than would be expected by chance and no larger than the within-groups variance.

    Article Summary: Through the act of touching someone, we communicate a variety of intentions, ranging from love or sexual desire to dominance or aggression. The authors of the study review results of previous research on interpersonal touch, showing, for example, that an innocuous touch of another person can have positive effects, such as increasing ratings of liking a person. There also appear to be differences both in the way that males and females touch one another and in how they...
