Gender: female; 1 male=0 EnrollmentStatus: 0 - Not General Education; 1 General Education Students CSR Participant: 1 -Taught by a teacher who was part of the comprehensive school reform professional development experience; 0- taught by a teacher who was NOT part of the comprehensive school reform professional development experience Reading score: Reading assessment score STATISTICS QUESTIONS Question 1: What is the impact of gender on writing vocabulary? Question 2: What is the relative impact of gender and enrollment status on writing vocabulary? Question 3: How well does the linear combination of variables in Output 3 explain writing vocabulary? Question 4: Based on your answers to Questions 1 2, and 3; what are your recommendations to the school principal?

Regression: First, choose any metric variable as the dependent variable and then choose any three other metric variables as independent variables. HOWEVER, this process must be repeated until you find a model that produces a significant F-calc (p-value (sig) <.05). Thus, you may have to sort through several combinations of dependent and independent variables before finding a combination that produces a significant F-calc. This is actually quite easy to do in SPSS using the drop down menus as shown in...

10. In Exercise 6, we examined the relationship between years of education and hours of television watched per day. We saw that as education increases, hours of television viewing decreases. The number of children a family has could also affect how much television is viewed per day. Having children may lead to more shared and supervised viewing and thus increases the number of viewing hours. The following SPSS output displays the relationship between television viewing (measured in hours per day)...

Suppose a researcher RW decides to give his nine participants a series of 50 photographs. He asks the participants to rank order (from 1-50) how well-dressed the individuals in the photograph were and to rank order (from 1-50) how intelligent they thought the individuals in the photograph were. One of the photographs was of a well known actor. The well-dressed rankings and the intelligence rankings for this one photo are as follows.
