14. In a study investigating freshman weight gain, the researchers also looked at gender differences in weight (Kasparek, Corwin, Valois, Sargent, & Mor- ris, 2008). Using self-reported heights and weights, Ded they computed the Body Mass Index (BMI) for each student. Based on the BMI scores, the students were classified as either desirable weight or overweight. When the students were further classified by gender, the researchers found results similar to the frequencies in the following table: Desirable Weight Overweight Males 74 46 Females 62 18 a. Do the data indicate that the proportion of over- weight men is significantly different from the pro- portion of overweight women? Test with a = b. Compute the phi-coefficient to measure the strength of the relationship. c. Write a sentence demonstrating how the outcome of the hypothesis test and the measure of effect size would be reported in a journal article. .05. 15. Research results suggest that IQ scores for boys are more variable than IQ scores for girls (Arden & Plomin, 2006). A typical study looking at 10-year-old
