7. Judge and Cable (2010) demonstrated a positive relationship between weight and income for a group of men. The following data are similar to those obtained in the study. The weight is measured in kg and the monthly income is measured in 1,000,000KRW. Based on the data given in the table below, can you conclude that weight and income have a significant relationship? Perform a correlation analysis at α = 0.05.

problem 9 presented data showing a positive relationship between weight and income for a sample of professional men. however weight was coded in five categories that could be viewed as an ordinal scale rather than an interval or ratio scale. if so, a spearman correlation is more appropriate than a pearson correlation. convert the weights and the incomes into ranks and compute the spearman correlation for the scores in problem 9. Weight (x) : 4 5 3 2 1 3...
6. A researcher wishes to test the effect of early discharge of cardiac patients on their ability to cope at home. The researcher administers the coping scale to 10 cardiac patients who were discharged early and 10 patients who stayed in the hospital for a longer period of time. Higher scores indicate better coping. Based on the data given in the table below, can you conclude that early discharge has an effect on cardiac patients’ on ability to cope at...

SPSS Homework 1 Instructions: Review and One-Way ANOVAs (40 points) Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups. Problem Set 2: Pearson’s correlation (7 pts) Research Scenario: Is there a positive relationship between...
