If a researcher reported an effect size (Cohen’s d)  comparing the difference between males and females on mathematics of -.01, what would be your interpretation of the size of the effect?

Describe the source of measurement validity evidence–Content Validity– from the Standards of Educational and Psychological Measurement. Describe the steps in conducting content validation of a data collection measure.

A researcher was interested in comparing the job satisfaction of male and female elementary school principals.   50 male principals and 50 female principals were randomly selected and were administered a 20 item job satisfaction questionnaire (Cronbach alpha = .001).  The responses to the questionnaire were combined to form an overall job satisfaction score. Evaluate the Cronbach’s alpha of .001.  

 List the independent variable(s) and dependent variable(s). Student shyness and hand-raising during class discussion

 List the independent variable(s) and dependent variable(s).   High school grade point average (GPA) as a predictor of students’ intention to attend college

A researcher is interested in determining the effectiveness of 2 methods of teaching fractions: Method A, visual models, and Method B, a number line approach.  40 students were randomly assigned to each method.  A 10-item fraction test is administered at the end of 8 weeks.   Identify the dependent variable.
