Read the paper, Significance of gender and age in African American
children’s response to parental victimization. Then complete the
following questions.
1. What is the research question? What are the independent and dependent variables, and decide their types.
2. Is it important to know the review board approval to conduct this research was obtained?
Do you think we should have a review board approval to conduct our last class experiment (Coke vs. Pepsi)? Why or why not?
3. The researchers state that they used a “convenience sample”. How you
understand the sampling method and what do you think will affect the
conclusion. What suggestion you can make to improve the experiment
design?
4. In your opinion, does the use of a control group make
this study an experiment study? Note: an experiment study controls
variables to a much larger degree than an observational study.
5.
The researchers use a three way ANOVA to analyze internalizing and
externalizing score. Do they discuss the interaction effect?
Draw a
two way ANOVA design plot (the mean plot you draw in class) to discuss
whether there seems to be any interaction effects of gender and age.
For example, the following tables is taken from table 1 in the paper and lists means of
External and internal scores for the exposure group.
Exposure group, internal score means
age group
6 to 8 years old
9-12 years old
gender
female
12.86
20.86
male
12.13
11.13
Â
Exposure group, external score means
age group
6 to 8 years old
9-12 years old
gender
female
8
5.57
male
14.88
23
Does
the two way ANVOA mean plot suggest interaction for the exposure group?
Describe why you think there could be or could not be interaction
effects.
