Distortion in the Pearson product moment correlation due to a restricted number of scale points is evaluated in two ways. First, a simulation of the bivariate normal distribution is used to estimate the effects of varying the number of scale points on the product moment correlation. This procedure demonstrates a substantial amount of information loss. Second, other correlation coefficients and some methods to correct for this loss are discussed and related to the simulation data.

Context: Health care professions have replaced traditional multiple choice tests or essays with structured and practical, performance-based examinations with the hope of eliminating rater bias and measuring clinical competence. Objective: To establish the validity and reliability of the Standardized Orthopedic Assessment Tool (SOAT) as a measure of clinical competence of orthopaedic injury evaluation. Design: Descriptive laboratory study. Setting: University. Patients or Other Participants: A total of 60 undergraduate students and 11 raters from 3 Canadian universities and 1 standardized patient. Intervention(s): Students were required to complete a 30-minute musculoskeletal evaluation in 1 of 2 randomly assigned mock scenarios involving the knee (second-degree medial collateral ligament sprain) or the shoulder (third-degree supraspinatus muscle strain). Main Outcome Measure(s): We measured interreliability with an intraclass correlation coefficient (ICC) (2,k) and stability of the tool with standard error of measurement and confidence intervals. Agreement was measured using Bland-Altman plots. Concurrent validity was measured using a Pearson product moment correlation coefficient whereby the raters' global rating of a student was matched to the cumulative mean grade score. Results: The ICCs were 0.75 and 0.82 for the shoulder and knee cases, respectively. Bland-Altman plots indicated no systematic bias between raters. In addition, Pearson product moment correlation analysis demonstrated a strong relationship between the overall cumulative mean grade score and the global rating score of the examinees' performances. Conclusions: This study demonstrated good interrater reliability of the SOAT with a standard error of measurement that indicated very modest stability, strong agreement between raters, and correlation indicative of concurrent validity.

The aim of this study is to investigate the relationship between strength, flexibility and balance parameters of male basketball players with performance dimension. Sixteen elite basketball players participated in the study voluntarily. Leg and back strength, flexibility and static and dynamic balance parameters of the participants were examined. Pearson Product Moment Correlation Coefficient method was used to determine the relationship between performance values obtained from strength, flexibility and balance parameters. As a result of the analysis of the data obtained; between LS and BS (r = 0.676 p < 0.01), SBRL and SBB (r = 0.787 p < 0.01), SBLL and SBB and SBRL (r = 0.688 p < 0.01, r = 0.791 p < 0.01), DBB and SBB and SBRL (r = 0.775 p < 0.01, r = 0.752 p < 0.01), DBRL and SBB, SBRL, SBLL and DBB (r = 0.800 p < 0.01, r = 0.694 p < 0.01, r = 0.707 p < 0.01, r = 0.874 p < 0.01), DBLL and SBB and SBRL (r = 0.765 p < 0.01, r = 0.652 p < 0.01) are high related. Whiler there was a moderate relationship between DBB and SBLL(r = 0.610 p < 0.05), DBRL and SBRL, DBB and DBRL (r = 0.588 p < 0.05, r = 0.589 p < 0.05, r = 0.566 p < 0.05), there were no relationship between FLX and LS and BS(r = 0.430 p > 0.05, r = 0.155 p > 0.05), SDİ SBB and LS, BS and FLX (r = 0.341 p > 0.05, r = 0.388 p > 0.05, r = 0.274 p > Z0.05), SDSA SBRL and LS, BS and FLX (r = 0.103 p > 0.05, r = 0.347 p > 0.05, r = 0.167 p > 0.05), SBLL and LS, BS ve FLX (r = -0.027 p > 0.05, r = 0.237 p > 0.05, r = 0.022 p > 0.05), DBB and LS, BS ve FLX (r = 0.211 p > 0.05, r = 0.306 p > 0.05, r = 0.268 p > 0.05), DBRL and LS, BS and FLX (r = 0.268 p > 0.05, r = 0.433 p > 0.05, r = 0.281 p > 0.05), DBLL and LS, BS and FLX (r = 0.136 p > 0.05, r = 0.137 p > 0.05, r = 0.164 p > 0.05). As a result, it is thought that the basketball players’ performance will be increased by paying attention to the content of training programs due to the sudden direction change actions of basketball, which are related to strength, flexibility and balance parameters of male basketball players.
