Q: 1a) With which of the following is the error term in an F test most closely asso

Solution: 1a) b) within-group variance F test — is calculated by dividing the between group variance by the within group variance. 1b) b) between-groups variability and error variability From abalysis of variance also we used to measure variabilty b/w groups and error variabilty. 1c) b) mistakenly performed and F test instead of a T-test

Question

1a) With which of the following is the error term in an F test most closely associated?

a) between group variance (was wrong answer)

b) within-group variance

c) main effect

d) interaction

1b) In a between subjects experiment with one or more IVs, what are the two sources of variability in the DV scores (i.e., the two reasons why scores in our data differ from one another)?

a) individual differences and extraneous variables

b) between-groups variability and error variability

c) error variability and measurement errors (was wrong answer)

d) how participants are assigned to groups and the number of IV's

1c) If you read F(3,28) = 4.16, p = .009 in a results section of a journal article, what can you conclude the researcher did?

a) rejected the null hypothesis

b) mistakenly performed and F test instead of a T-test

c) mistakenly swapped degrees of freedom numerator for denominator (was wrong answer)

d) failed to reject the null hypothesis

Explanation / Answer

Solution:

1a) b) within-group variance
F test — is calculated by dividing the between group variance by the within group variance.

1b) b) between-groups variability and error variability
From abalysis of variance also we used to measure variabilty b/w groups and error variabilty.

1c) b) mistakenly performed and F test instead of a T-test
