Question

Question 1

PART A)

We have 678 observations with two IVs, education and partyid, and one numerical DV. Education is measured with 5 levels/groups and partyid includes 3 levels/groups. Fill in the appropriate degrees of freedom for each effect/variance component below.

ENTER DFs AS INTEGERS.

Variance component	Degrees of Freedom
education
partyid
education:partyid
residuals
total

PART B)

Fill in the blanks in the ANOVA table below. You have enough information to make these calculations.

ROUND ALL ANSWERS (EXCEPT DF) TO ONE DECIMAL PLACE - DF SHOULD BE INTEGERS

SOURCE	df	SS	MS	F
Factor A		778.5	259.5
Factor B	4	3529.2		10.2
Interaction	12	6850.8	570.9
Residuals		6920.0	86.5
TOTAL	99

PART C)

Referring to the ANOVA table you completed in the previous question, given a critical F-value of 2.49, is Factor B statistically significant?

a) Yes

b) No

Answer 1

Ans1

PART A)

Variance component	Degrees of Freedom
education	4
partyid	2
education:partyid	8
residuals	678-15 = 663
total	677

PART B)

Fill in the blanks in the ANOVA table below. You have enough information to make these calculations.

ROUND ALL ANSWERS (EXCEPT DF) TO ONE DECIMAL PLACE - DF SHOULD BE INTEGERS

Factor B	4	3529.2	882.3	10.2
Interaction	12	6850.8	570.9	10.10
Residuals	80	6920.0	86.5
TOTAL	99

PART C)

given a critical F-value of 2.49 yes Factor B is statistically significant

a) Yes
