1. How many subjects?  How were they selected?

2. What general population are these subjects representative of?

3. 42% of the subjects in the sample display symptoms of depression.  The
   newspaper article says, "The finding strengthens the popular belief ...".
   But what if 42% of the mothers of children of other ages--or nonmothers--
   display symptoms of depression?  (To address this issue, the report 
   presents results from comparison groups--comparable women who are not
   mothers of two-year-olds.  Where in the article are comparison groups
   mentioned?  What are the groups and what are their depression rates?)

4. If you could do a study of one more comparison group, what would that
   group be?

5. The numbers in Table 2 are presented to 3 decimal places.  For practical
   purposes, would it be OK to use just 2 decimal places?  What about 1
   decimal place?

6. A big thing in the report that is not mentioned in the article is a
   comparison of rates of depression among different groups of mothers of
   two-year-olds.  If you could add another paragraph to the Science News
   article to cover this topic, what would you say?

7. If you had to remove three sentences from the Science News article, what
   would they be?  Why?
