_ In a correlational study, two methods were utilized to compute percent body fat among athletes. A total of 16 athletes were measured using ultrasound and x- rays. The results were as follows: Athlete X-Ray Ultrasound 1 5.00 4.?5 2 100 3.75 3 9.25 9.00 4 12.00 11.75 5 1125 17.00 6 29.50 2?.50 7 5.50 6.50 8 6.00 6.75 9 8.00 8.?5 10 8.50 9.50 11 9.25 9.50 12 11.00 12.00 13 12.00 12.25 14 14-00 15.50 15 17.00 18.00 16 18.00 18.25 Since the sample size is too small, we cannot assume a normal distribution. Used the Wilcoxon Signed Rank Test to determine if there is a signicant difference between the two methods in determining body fat.
