Suppose a researcher conducts a two-factor study comparing two treatments (I and II) for college graduates versus adults with no college experience. The structure of the study is shown in the following matrix.
Treatment
I. College graduate..
II. No college.
a. If the results show that college graduates have higher scores than the no-college adults in treatment I and equivalent scores in treatment II. is it likely that there will be a main effect for the education factor? Is it likely that there will be an interaction?
b. If the results show that college graduates have higher scores than the no-college adults in treatment I and lower scores than the no-college adults in treatment II, is it likely that there will be a main effect for the education factor? Is it likely that there will be an interaction?

- The data set hemorrhage.sav contains a sample of 100 low birth weight infants born in Boston, Massachusetts. Germinal matrix hemorrhage (gmh) is a dichotomos variable that coded as 1 if the baby had a hemorrhage and 0 if the baby did not have a hemorrhage. You wish to know if head circumference, systolic blood pressure (sbp), and gender predicts hemorrhage. (See the attached Image) 1. What are the null and alternative hypotheses for this analysis? (hint: there should be 4 sets) 2. Is the model as a whole significant?

The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables affected total help if he rejects the null hypothesis. Below is the data set followed by the results:arrow_forwardA researcher wants to see if gender and/or income affect the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help.
