The dependent variable is "Negat" (how many time the mother gives negative feedback to her child during the data collection protocol)

The IVs are the (mother's treatment status) and (child's age group)

1. What are the three effects in this factorial design?

2. Complete the factorial analysis and fill in the table below (don't forget he marginal means). Type the means for each combination of variables in each cell and the marginal means for each main effect.

Mother's Treatment Status

No Treatment                Treatment

Child's Age

2-3 years old

4-5 years old

3. Find the results of the test of the interaction:

F = _______  df = ____, ______  p = _______  MSe __________  

Is there an interaction ??? _____________

If appropriate, show the pattern of the interaction - use simple effects of Mother's Treatment Status for each Age

4. Use <, >, or = to show the pattern of the simple effect of Treatment Status for 2-3 year olds

5. Use <, >, or = to show the pattern of the simple effect of Treatment Status for 4-5 year olds

6. Is the pattern of the simple effect of Child's Age Group different for 18-27 & 28-35 year old mothers?

Write up the interaction results below - be sure to follow the example in the spss handout.

Find the results for the test of the Main effect of Treatment Status

F = ________  df = ____, _____   p = ________ MSe ____________

 Is there a main effect ??? _____________

If appropriate, check if the main effect of Treatment Status is descriptive or misleading ...

• Use <, >, or = to show the pattern of the simple effect of Treatment Status for 2-3 year olds
• Use <, >, or = to show the pattern of the simple effect of Treatment Status for 4-5 year olds
• So, is the pattern of the simple effect of Treatment Status different for 2-3 & 4-5 year olds?
• So, is the main effect of Treatment Status descriptive or misleading?

Write up the main effects results below (including whether it is descriptive or misleading) - be sure to follow the example in the spss handout.

Find the results for the test of the Main effect of Child's Age

F = ________  df = ____, _____   p = ________ MSe ____________

 Is there a main effect ??? _____________

If appropriate, check if the main effect of Child's Age is descriptive or misleading ...

• Use <, >, or = to show the pattern of the simple effect of Child's Age for mothers who have received no treatment
• Use <, >, or = to show the pattern of the simple effect of Child's Age for mothers who have received treatment
• Is the pattern of the simple effect of Child's Age different for those who received and did not receive treatment?
• So, is the main effect of Child's Age descriptive or misleading?

Write up the main effects results below (including whether it is descriptive or misleading) - be sure to follow the example in the spss handout.
