Under what research circumstances does one make a directional hypothesis in the real world of research? What is Homogeneity of Variance? Explain what Levene's test on SPSS does. Define and give an example of Matched Samples Define and give an example of Repeated Samples Next are the Computationals: Make sure you do all the steps needed and don't forget to label your steps! Remember if you reject H0 you will need 7 steps but if you retain H0 only need 5 steps. Independent T-test: Do people who complete college have a higher salary than those who drop out after one year? We start with 10 people enrolled in college. Some dropped out (conveniently for us it was 5 people). A year after completing college or dropping out of school we ask the participants to report their salaries per year. The data is below (it is in thousands such that 50 =50,000 but use the 50, 70, etc. for calculations). What can we conclude? College degree data: 50, 70, 30, 50, 50. College dropout data: 30, 20, 30, 0, 10 Dependent T: Two matched groups of sixth graders were given Form A and Form B of an intelligence test. The data obtained is below. Assume the researcher predicted the scores on Form B of the test would be higher than Form A. What can the researcher conclude? Data Form A (X1) Form B (X2) 9 10 12 14 15 13 10 7 11 7 15 12 8 9 9 12 7 6 10 14
