Question

An intervention program with mothers of low birth weight infants (LBW). It is often difficult to recognize signals from LBW infants, and the program offered training in this domain. One group of mothers received instructions on responding to subtle signals of LBW infants while another group did not receive such instruction. A third group of mothers of normal birth weight infants served as a control group. The mothers were also divided by education level-high school education or less and more than high school education.

How many independent variables are there?

What type of analysis should be performed?

Answer Choices:

3 x 2 ANOVA
