Submit your answers to the following questions using the
ANOVA source table below. The table depicts a two-way ANOVA in which
gender has two groups (male and female), marital status has three
groups (married, single never married, divorced), and the means refer
to happiness scores (n = 100):

  1. What are the independent variables and their levels? What is the dependent variable?
  2. State all null hypotheses associated with independent variables and their interaction? Also suggest alternate hypotheses?
  3. What are the degrees of freedom for 1) gender, 2)
    marital status, 3) interaction between gender and marital status, and
    4) error or within variance?
  4. Calculate the mean square for 1) gender, 2) marital
    status, 3) interaction between gender and marital status, and 4) error
    or within variance.
  5. Calculate the F ratio for 1) gender, 2) marital status, and 3) interaction between gender and marital status.
  6. Identify the critical Fs at alpha = .05 for 1) gender, 2) marital status, and 3) interaction between gender and marital status.
  7. If alpha is set at .05, what conclusions can you make?
Source Sum of Squares (degrees of freedom [df]) Mean Square Fobt. Fcrit.
Gender 68.15 ? ? ? ?
Marital Status 127.37 ? ? ? ?
Gender * Marital Status (A x B) 41.90 ? ? ? ?
Error (Within) 864.82 ? ? NA NA
Total 1102.24 99 NA NA NA

Please Note: The table that you see in
the assignment has been slightly modified from the one presented in the
module notes since it is beyond the scope of this unit to have students
calculate p values. Instead you are asked to calculate the F value and
compare it to the critical F value to determine whether the test is
significant or not.
